  • Our Throttle Position sensors are made by implementing a proprietary sliding contact technology, based on multiple precious metal contacts riding on polymer thick film resisters to offer a longer working life than competitor sensors on the market today. Each of our sensors is provided with integral rotor bearings and return springs which allow for easy installation when compared to the spring-less designs currently available in the aftermarket, which rely on worn throttle body bearings and return springs to set the correct output voltage. Our sensors maintain specific installed outputs to match the OE rather than using adjustable, consolidated designs. Engine management systems require reliable connections in order for sensors to reach the optimum performance level. We manufacture our sensors to ensure that both external and internal connections remain reliable in order to maintain these requirements through the product life. Each sensor that we offer endures rigorous end of line testing which involves many thousands of data points to validate output voltages and to ensure that each part meets linearity specifications that are expected by the engine management system in your vehicle.

96 Saturn s1 - idle problems

Showing 4 out of 4 Posts
Question From juniorinky on 96 Saturn s1 - idle problems

I am working on a 96 Saturn s1. whenever I shift gears the idle won't drop. it will eventually drop but I will already be in the next gear. I took the throttle body off and cleaned it up really good. it was really nasty. there are no vacuum leaks it idles perfect at 750 rpm. no hesitation and no miss. I am at a loss. I am thinking either the throttle positioning sensor or the maf sensor. but I don't want to buy parts just to throw on it. any help will be greatly appreciated.f

Response From Discretesignals

Check the coolant temperature sensor. See if it is cracked.

Response From juniorinky Top Rated Answer

Thanks.That is what it was.I noticed that it was running a little cooler than normal. but I never thought about the coolant sensor I replaced it and everything is fine now thanks. the temperature gauge showed a little cooler than normal but I thought that was just maybe the way they ran.My truck gauge shows right in the middle and this runs about quarter of the guage.Installed a thermostat and it reads in the middle of the guage.Really dont know if it was the thermostat being stuck open or the sensor though but replaced both.

Response From Hammer Time

That's why you need an good scan tool to monitor all the sensor data so you can look for things like that.

1995 satur died last night will not start

Question From tnpa on 1995 satur died last night will not start

My son was driving his 1995 saturn SL2 home from work last night. It died suddenly. Did not make any noise, has a full tank of gas, weather cold (12 degrees), and now will not start. He says it makes a whining noise and then quits. Any ideas?

Response From Tom Greenleaf

A guess you don't want to hear: Cold might have been the straw to allow a neglected rubber timing belt to break. Engine would sound funny or interferrence engines damage valves or more and may not crank over

Hope not,

T

Response From tnpa

Thanks for the advice, but the saturn has a timing chain. Suppose it could have broken, but my son says no noise, no nothing. It just died and coasted to a stop. No service engine lite either. Still baffeled

"He says it makes a whining noise and then quits. Any ideas? "

Does that mean it cranks and makes a whining noise but doesn't start? It is true that real chains don't usually just up and break. I find they give more symptoms even if they are the problem.

So just when does this noise happen and does the engine crank/turn at all? If you look at regular belts the engine is turning - need to know that,

Response From tnpa

I suggested that he try to jump start it thinking the battery might be weak. After this attempt it makes no noise at all. The key turns and now there is no noise. Acts like the starter solenoid may be gone, but this does not explain the sudden loss of power before. Sorry for the explanation being iffy. Working through this over the phone. Car is at my son's house.

Response From Tom Greenleaf

Ok: Has the car lost all electrical power? That would shut the car down. You're right - the solonoid is just the connection to the starter. Battery cables at all ends must be clean and tight, a jump may still be needed as the battery could be down now and if it starts up check the charging volltage, and condition of battery itself. they can short out inside - more likely when older. How old is it?

If the engine was trying to stay on and then died. You flooded the engine, give it gas while starting it, To clear it, I have a 95 Saturn, in the cold it did that cause the Throttle Position Sensor, and both Temperature Sensors needed changing. Get aftermarket parts, the ones from the dealership are garbage. If the engine gets too hot, its time to do the thermostat, and waterpump. Very easy job.

Question From saturn nightmare on 2001 Saturn SC2 Transmission Trouble. Please Help.

I am having trouble with my 2001 Saturn SC2. The transmission is slow to shift into reverse. It drives in 1st, revs to 5000 RPM and shifts to 2nd, same to 3rd.Then it stays in 1st(possibly a limp mode. I replaced the tranny and the new one is doing the exact same thing. Please help if possible. Thank you

You replaced it with a new tranny or wrecking yard tranny??

Did you pull codes to see if there were any stored tranny codes?

Response From saturn nightmare Top Rated Answer

I replaced it with a junkyard tranny and it has the same problem exactly as the original tranny. 3 codes P0732, P0733, P0734. Slow to shift into reverse, Goes into 1st fine revs before shifting to 2nd, revs before shifting to 3rd, then stays in first until you shut car off and restart. Genesis scanner reads these codes under engine/PCM but scanner will not read under transmission it says check that ignition is on, connection is good, etc. I find it hard to believe that I have 2 transmissions with the exact same failure. I allready replaced the throttle position sensor, did not fix it.

Help. 2002 Saturn L200 slipping gears

Question From GrilledCS on Help. 2002 Saturn L200 slipping gears

Hello,

2002 Saturn L200 automatic 4 cyl. 2.5l app. 110,000 miles

On Monday, driving to work, I noticed my car was slipping gears and when I would push on the gas at around 50MPH I would have to floor it to get up to 60MPH. I pulled off and went to the same repair shop I've been using for years.

I was told that I needed a new catalytic converter because mine was clogged. So, I got the new cat converter and new 02 sensors. ($1000). The next day (yesterday) the car isn't driving very well thudding when I put it into drive and still slipping gears. Then my battery and check engine light come on. I go back to the repair shop. My serpentine belt had broken and some wires were damaged as well The shop replaced the serpentine belt, pulley, etc and wires free of charge. But the car is still slamming into drive and slipping gears. The mechanic checked my transmission fluid and it wasn't too dirty. Also, he didn't get any codes for the transmission on the code reader, but the check engine light won't go off. At this point, the shop was closing for the day and I was told to try back with them at my next availability.

I've used this shop for some time and believe them to be honest and they've been cooperative about helping me. I asked them if they were sure it was the catalytic converter initially and they said it was because they had checked the exhaust flow. The garage doesn't seem to know what the problem is.

How can a catalytic converter, a serpentine belt and (possibly, let's hope not) a transmission all go south on the very same day?

From doing my own research (and I'm not a mechanic, even in the driveway sense), I'm wondering if the real culprit is the throttle position sensor (TPS). Anyway, anyone who can lend some insight, it would be appreciated.

Response From Sidom

Some things are easier than others to nail down online..... This problem is tough with out being able to drive it.

As far as the problems, it sounds like they had slowly be going out for a while and are starting to fail now.... The belt breaking had probably be cracking for a while before breaking. Converters are the same, unless you have a severe drivability problem, it takes a little while to take them out.

Sounds like you have a good shop for most of you needs but some shops don't cover every area. If they don't do tranny work you may want to take it to a tranny shop and get a second opinion. From what you posted, it sounds like you may have a tranny problem & mechanical problems won't show up on a scanner but I can't drive this car so I don't want to start 2nd guessing your tech.....

Response From GrilledCS Top Rated Answer

Thank you very much for your reply.

You're correct on the serpentine belt. I'd gone to the same shop regarding a squealing only four months ago. As I mentioned, my impression is that this shop is sympathetic to its customers. They told me in September that they were going to replace the serpentine belt, the pulley, and the tensioner. When they told me the price, I guess they noticed that I winced at the cost.

From there, I think they said to themselves "This guy's a regular customer. Let's try and help him out". The mechanic then re-emerged from the garage and said, basically, "From what I can tell, you just need the tensioner." So, they replaced that.

The squealing recently returned. Because I'd just replaced the tensioner, I chalked it up to wet winter conditions. I then started noticing a difference in power. The car just didn't feel right. So, I said to myself, "Okay. I'll have it checked it when I get a chance." The car was not slamming into drive or slipping gears at that point, which was only a few days ago.

Since all of these things are going wrong within 36 hours, I have to conclude that they're all somehow related. It's simply too unlikely that a serpentine belt would break, the catalytic converter would get clogged, and the transmission would start having problems all in less than 36 hours.

Since I now know that the first problem was the serpentine belt, I'm led to believe that this was somehow the major culprit regarding the other problems. Since wires were damaged by the serpentine belt, I'm thinking that other components may have been harmed by the serpentine belt failure. I've read that parts of the serpentine belt can fly off and cause engine damage before the belt actually breaks.

I'm currently driving the car. Between gears, it now drives beautifully. Also, the transmission doesn't slam when I put it into reverse. It only slams when I put it into drive. If I ensure that I'm at a full stop and gently shift into drive, it won't slam at all. But it still slips gears, except when I'm in (I believe) fifth gear and going over 45 or 50 mph. Then it drives smoothly.

I asked my garage how they determined that the catalytic converter failed, and they told me immediately and sincerely that they checked the exhaust flow. However, I don't think that anyone ever actually eye-balled the cat converter itself. Also, I don't think the check engine light came on when I was having the acceleration problems that caused me to go to the garage, but it might have without me noticing it. (Nonetheless, I've learned not to have great faith in "check engine" lights)

I'm not a mechanic, but I'm trying to be logical about the whole thing.

Whatcha think?

Response From nickwarner

first off, thank you for trying to look at this problem informed and not blame the last guy who worked on your car. You are rare in this world and us mechanics appreciate you. It does seem unusual that all these items happened in a very short time, but you haven't had reason to doubt this shop before. Honestly, an exhaust flow test is more accurate than an eyeball at a cat any day. If you had replaced the tensioner, belt and idler pulley together you could've saved the belt snapping and taking out wires. I don't replace the tensioner and leave the old belt behind. Just asking for trouble, which you now see. It came back to haunt you. I wouldn't consider this anything more than a coincidence for the timing that it chose to fail. It was bound to happen. Also, this is an 8 year old car that in my opinion was poorly designed and not made to do more than sell for cheap and barely outlast the warranty. To have a transmission on the way out is not a surprise in the least, and neither is your clogged cat. If anything, the cat neutered your engine for a while, gradually, to not make enough power to show the flaws in your transmission. Now that its fixed, all the problems are made apparent. They may seem to happen all at once, but are not related. Best of luck to you in your repairs. I would do as suggested, and have a shop specializing in transmissions look it over.

Saturn SL2

Question From fatshady on Saturn SL2

This 96 SL2 (165,000) has the dohc setup with a 5 speed. we did some work on it a while back and left the intake air temperature sensor unplugged and it ran terrible till we found that (through a scan at autozone) and stuck it back on. Though much better the car still intermittantly stumbles. It is a little hard to start but always will with full static throttle. Lays a little blue cloud each time it starts from cold. It tries to die when idling during the first minute or so, then drives normally most of the time. Occasionally, and without warning even after warmed up, it will stumble when revving to take off from a stop. During the times that it is showing this symptom, it can be revved up with the right touch on the accelerator, but cuts out at 4K or so rpms and then catches again immediately, over and over. After a tantrum like this it goes again like everthing is fine. I have now driven it enough to burn a tank that had Lucas fuel system cleaner in it. It is still just not quite acceptable to turn back over to my daughter. The engine light has stayed off since we reconnected the IAT sensor. What should we do next?
Before my daughter bought this car we drove some other saturns that had automatics. in 2 separate cars i put them in reverse and backed up as fast as i thought prudent to see how it would act. both cars cut out at a certain speed like 15mph, and we talked to a tranny shop who told us not to buy either car. Since then i have talked to a mechanic about this who said that it was a design feature to prevent a car from going too fast in reverse and was nothing to do with a faulty tranny. I bring this up because when the car is in this cutout mode it acts very similarly to what those automatics did.

Response From DanD Top Rated Answer

Sorry I didn’t get back to you over on Venturi’s site, I kind of forgot about it, as your post was in the “introduce yourself” forum.
You may need to check things like fuel pressure and volume while it’s doing its thing, it would also be handy to now what the scan data is while the car is acting up. You may have a sensor that is beginning to fail but is still within its perimeters and not setting a code.
You’d be amazed what a TPS (Throttle Position Sensor) can do if it jumps from .5 of a volt to lets say 3.5 volts, the poor computer thinks you just jumped on the throttle and throws a whack of fuel at the engine, causing it to flood out.
Now I’m not saying it’s the TPS but just using it as an example, because the computer knows that around .5 of a volt is closed throttle and at 4.5 volts is wide open. Anything in between is normal for the computer to see, depending on where your foot is on the throttle. It’s a variable resistor something like a dimmer switch in your house that can turn your lights in a room from full bright to dim.
Sorry but you may need to go to someone that has a good understanding of the system and can properly interpret scan data, scanners are used for more then just reading codes.
Dan.

Response From fatshady

Thank you. That makes sense. It really acts to me like a control system/sensor/interpretation problem and though i hate to involve a professional and pay money i have to admit that there are times when i am glad they are available. These modern systems don't always respond well to a bigger hammer or let some air out of the tires.
Meanwhile i brought home a fuel filter that i figure is a maintenance item anyway and it will keep me busy while I am processing my mechanical limitations. Actually, I think I'll poke around a little more and see if i can get the car to flinch somewhere.

Response From Tom Greenleaf

You mentioned you left a wire off the air cleaner and used some fuel solvent. Dan mentioned the TPS which can cause all kinds of trouble. For the price I'd consider a new set of plugs too. Just a thought, - T

Response From fatshady

I think a real mechanic could sometimes be disgusted by the guys like me who hit on a suspicion and buy a part and stick it on without really knowing what is the cause of the problem. Like a competent doctor, a good mechanic with equipment and knowhow can (usually) pinpoint the diagnosis and fix what is really the matter without replacing much of what is under the hood every time. This is the essence of a good practice. The shadetree tinker comes along and gets his car fixed eventually, sometimes suddenly, but without the finesse that a real artist can muster and it is just less inspiring- less pure. I apologize that I am in the latter camp. I say that with deference to and respect for the masters who generously share their understanding and enthusiasm, as on this site. This help is invaluable. Even so, I am pretty sure that I am way ahead of the game using natural curiosity and the experience that has been forced upon me through the slings and arrows of outrageous fortune for the last 30 or so years being a DIYer.
I replaced the plugs, cables, and coil packs last week, and the fuel filter this week. A TPS is only 21 bucks and I may go for that next. I have a test procedure for it in the Haynes manual but for the time and money I'd just as soon put a new one on there and know its done. I'll let you know what happens.

Response From fatshady

I put a new TPS on last night. It was more difficult than expected as the 2 little star fasteners that hold it on are backed right up to the firewall. For the time and money I might have been better off finding the VOM and running through the check procedure after all.
No change in behavior. It revs to about 4200 then cuts out and drops to 4000 or so and back up, cuts again, over and over.

Response From motorheadII

Just a thought. What you're describing could be the normal function of the rev limiter that is programmed into most ECMs.

Response From fatshady

Hmm. That sounds like a possible explanation for the cutting out at high rev. Perhaps it would be the same function but at a lower rpm when in reverse. I did finally run the check on the IAT sensor. I got to thinking that even though i had it disconnected for a little while and that was a significant problem, it still could be going out. Seems to change resistance smoothly within the right values. I may just need to drive the car a little more. Maybe bring it in to work for a few days and see what happens.

Response From fatshady


I have driven the saturn to work the last 2 days (15 miles each way) and it has not stumbled or whimpered in any way. When I checked the IAT sensor a couple of nights ago i looked at the connection more closely before sticking it back on. it looked like it might be possible to reverse the plug orientation. Is that possible, and would the sensor act differently if the polarity were reversed? It had the right control voltage (5v) and it looked like a little shoulder inside the plug might be slightly rotated to prevent wrong connection. the plug is pretty small and a little deformed by now so I couldn't be sure about it. I would be pretty happy if that is all it is. I plan to drive it a couple more days before giving it back to the kids.

Response From fatshady

So here is the final outcome. the car was not fixed in november as i was hoping, but it was not needed as my daughter went overseas and is still in germany. the car has been sitting parked until i found time to get it fixed and sell it for her. we took it to a guy that works on a lot of saturns and he found the real problem-the coolant temperature sensor. it was telling the main computer that it was cold all the time, hence the too rich mixture and the stalling after warmup. the cutting out at 4200 rpm and kicking back in at 4000 is normal. it has a high-rev sensor to protect the engine. well, thats the story. maybe it will help someone else. thanks for all the help offered here.

Response From DanD

I’m not sure what else to suggest, with out getting under the hood with you and doing some actual testing. Other then going back to the basics and looking for vacuum leaks, sort of that it maybe time to throw your hands up and take it in.
Sorry.
Dan.
