O2 Sensor

Showing 2 out of 2 Posts
Question From Guest on O2 Sensor

Hello,

I have received labor estimates of $250 to $300 to replace an O2 sensor in a 2003 Mitsubishi Gallant, 2.4L engine. My layman's research indicates that this is way too high for what's involved. Am I right or wrong?

Thanks,
Joe

How many esimates do you have? If you have a few then you'll probably find your converging on what the market will charge, hence its what you'd have to pay to have someone do it regardless of the difficulty.

Mitsubishi Eclipse stall/idle

Showing 5 out of 5 Posts
Question From skylerbite23 on Mitsubishi Eclipse stall/idle

2003 Mitsubish Eclpise idle/stall?
I have a 2003 Mit Eclipse RS. Automatic. 90K miles. 2.4L 16 Valve. Car started stalling during deceleration and stop signs. Only would happen while foot not on accelerator. Took to my mechanic. Got 2 Codes. Misfire and Bad O2 Sensor.
Mechanic suggested follow the misfire. Replaced all plugs, electrical box, wires, tune up, oil change $360 later did same thing. Next got second opinion. This mechanic cleaned throttle body and IAC. $120 dollars later same problem. Finally, took to Mitsubishi. They suggested always follow the computer and replace O2 Sensor. $175 later still idles poor. Feels like gonna stall but doesn't. Don't know what to do or where to take next. Thats 3 mechanics NO ROOT cause. Everyone treating symptoms not some tricky cause. Read that only other cause could be small hose that you can only tell is bad when its opened up but seems like long shot.
Anyone have/fixed problem like this please let me know.
(Since 02 sensor change runs better untill A/C turned on
and SES light has come back on)
Please help!!!!
Thanks, Sky

Other Info- 6 months ago- Replaced radiator, therm, all belts $725
4 months ago New battery and housing

Response From skylerbite23

Thanks for quick ideas. The IAC and throttle body were cleaned not replaced. The idle bounced around after that up and down. Unplugged neg battery to reset it. Then it died no idle hold but runs great while driving. Thats when i took to Mitsubishi. the tech took me back and had my "bad" 02 sensor off and had car hooked up to some kind of bypass. The engine was humming great in idle. Showed me on hood suppose to idle between 600-800 RPMs. Thats why I replaced sensor. Could i need to turn the idle UP? I dont know how to do much with cars so maybe ill take it back to Mitsubishi ask them to do it. I brought up 3 mechanics cause on researching this issue ive read some valve may be stuck open. IAC motor fried. MAS bad.. Im just running out of cash. Figured one would say Ahh thats the problem. The SES light is back on after AC turn on and idle dipped. Ill bet its another misfire cause sounds again like its on 2 cylinders. Car runs and idles fine til AC goes on then idle drops. Round and round i go. Anyone know of a Dr House like mechanic in the tampa, Fl area.

Response From Tom Greenleaf Top Rated Answer

I don't know of any regulars here in Tampa - many in FL but not there.

Again - idle should dip (perhaps a second or two) with A/C - there's the clue too for IAC troubles,

T (off line for some time now - good luck)

Response From Tom Greenleaf

3 mechanics and still not right? Mitsu dealer even. Dealer doesn't mean the tech was finding it. SES on again so you need codes read yet again. It just can't hold a proper idle it seems which is greatly the IAC and clean may not be enough it may need to be replaced or was all that cleaning done properly enough? Can't know if 3 mechanics are failing.

Turning on A/C is a fair extra load on engine and if idle can't compensate then it would idle too low and set a code. Codes don't say exactly what to do or replace just what it sees. You can unplug something and get a code that doesn't tell anyone that circuit XYZ is unplugged just that, that is the area of the problem to chase down.

You may need mechanic #4. Does it start up cold and hold a fair idle? Probably not so IMO that IAC either gets wrong info or is bad OR needs all cleaned up again which shouldn't be the world to do.

Even you could do a careful "wiggle" test at idle if it will on assorted vacuum items and wiring connections and if anything changes point that out to a mechanic as it seems you have a clue but don't do your own work,

2000 Mit Diamante codes 0173, 0170 & 0421

Showing 2 out of 13 Posts | Show 11 Hidden Posts
Question From comnavguy on 2000 Mit Diamante codes 0173, 0170 & 0421

This 2000 Mitsubishi Diamante with 137K miles won't pass inspection.

Code P0170 fuel trim malfunction Bank 1
Code P0173 fuel trim malfunction Bank 2
Code P0421 warm up catalyst below threshold Bank 1

What is this, and what repairs are required?

Thanks.

Response From Hammer Time

Your probably going to need a scan tool here. The codes are pretty generic and only indicate that the fuel is either too far rich or too far lean. It doesn't tell you which so you have to determine that with the scan data. You also have to look at all the sensor data for a cause like the temp sensors both intake and coolant, MAF and the MAP sensor.

The 421 is probably an early sign of a failing converter.

Response From comnavguy

I hope this is not a duplicate. I was composing a reply and the space went blank except for a few words???

It was: Tell me about a scan tool. Who is most likely to have one?

And, what is bank 1 and bank 2 on a single exhaust vs a dual exhaust car; single catalytic converter vs two ?

A scan tool is a basic computer interface tool. Most shops have one. Bank one will be the side of the engine where #1 cylinder is.

Response From comnavguy Top Rated Answer

Will this scan tool tell us exactly which sensor is bad and if the catalytic converter is bad or not?

How can the O2 sensors be tested?

Response From Sidom

Like HT mentioned, this one would require a scanner and you would have to be able to interpret the fuel trims that could cause them to go out of range..... Normally you'll get P0171 & P0174 or P0172 & P0175 codes, the 1st are lean bank codes & latter, rich bank codes, these ones don't even break that down for you. The banks refer to each side of the engine. A 4 cyl will only have bank 1.

So right now you don't know if you have lean codes or rich codes...... 1st step would be to look at the fuel trims and find out.....positive trims would be lean, negative trims, rich...... Lean codes could be be your air intake tube from the air cleaner off, hose off, split in it, it could have a vacuum leak, exhaust leak, all that stuff you could do a visual on. HT mentioned a few things that could set rich codes.....

With those codes, there is just too many things it could be, it needs to be narrowed way down..........But like I said, do a basic look over & look for something obviously broken, off, or hissing noise (vacuum leak)


Damn dude.....How many cars do you have..............lol

Response From comnavguy

I DO have an Actron CP 9180, and have scanned this vehicle. But what oh what does it all mean?

ST FTRM1 14% (Short term-fuel trim ratio bank1)

LT FTRM1 12.5% (long term-fuel trim. Air to fuel ratio bank 1)

ST FTRM2 11.7%

LT FTRM2 12.5%

O2S11 .14 Volts to .74 volts

O2S12 .06 V to .32 volts

and there are lots of other readings which mean just as much to me.

Translation, PLEASE?

As for all the cars...I am retired and one of my neighbors caught me working on my car one day, asked me if I could help him, and it's snowballed from there. I am the go-to-guy for friends and neighbors with "problem" cars. Sometimes it's fun and keeps me out of the street. I'm down to 2 personal cars, just having sold an 89 Olds, 92 Merc and a 91 Sedan DeVille.

Thanks and Happy and safe 4th

Response From Sidom

As HT said those don't look to bad at all, skewed slightly lean but not to bad but both banks are towards the lean side....

Before you clear the codes, do you have access to freeze frame data? If so post that up.

Get someone to drive for you and go for a spin. See what the trims do at high speed, see if they get closer to the zero or single digit range...


Yea working in the driveway can always be a hazard.......

Personally I always try to set something on fire every so often, beat stuff with a big hammer, cuss uncontrollably and every so often chase one of the grandkids around with a ratchet....
For some reason, neighbors requesting advise or repairs really isn't a problem for me......

Response From comnavguy

My scan does have a freeze function. Tonight I'll try to run the tests suggested, freeze the data and post it.

Where and how does one adjust the trim functions with the computer actually doing the trimming? I'll have this car tonight for long enough to run it through some paces - highway and surface streets.

Thanks for the help so far.

Hope you guys had as good a 4th as I.

Response From Hammer Time

That's not what he was referring to. Most scan tools will freeze frame all the sensor data at the moment a code was set and store it for later use so the tech can see what was going on when the code set.

Response From comnavguy

The owner has put this car and problem on the back burner. The car is parked until she gets some money.

When she gets the money, we are going to do more troubleshooting.

Thanks for the help so far.

Response From Hammer Time

Your fuel trims aren't really out of the norm as the code would have us expecting. You might want to clear out all the codes and drive the car and watch what those fuel trim reading do. See if they start a trend going positive or negative and whether it sets the codes again. It may take more than one trip to set the codes.

You have a long term trim and a short term trim for both banks. Those readings are telling you just how much the computer has had to adapt to conditions in the engine so your watching for the computer having to work to overcome something either too rich or too lean, depending which direction those readings are moving. Right now yours are slightly positive on both banks but well within the range of adjustment and staying fairly even.

2001 Mitsubishi Mirage Turnsover but will not start.

Question From mfenix13 on 2001 Mitsubishi Mirage Turnsover but will not start.

My vehicle info:
2001 Mitsubishi mirage DE Coupe
1.5L Engine
Manual Transmission
170,000+ Miles
The Problem:
About 4 months ago there were heavy rains where I live and I ran into high water and my car shut off. I let it sit overnight and it started right up the next day. 2 months later the battery went dead, then the alternator died as well. I fixed those issues and about 2 weeks ago I started having starting issues. They are intermittent. The car turns over but will not start. I have to try over and over and over again before it finally starts after about 10 minutes. Once it starts, the vehicle is fine. It runs smooth and it does not cut off, nor are there any signs that anything is wrong. Once its off I can start it back up, most of the time. Today it started in the morning but it sounded like it wanted to cut off, I hit the gas and it started to idle smoothly and it stayed on without me having to hold the gas down. I drove it to work with no problems. When I got off it started but immediately cut off, I can't even hit the gas, it just shuts off.
What I've done:
I've installed new: battery(2mos ago), alternator(2mos ago), sparkplugs, wireset, distributor cap(2wks ago) . The problem started before I replaced the sparkplugs, wireset and dist cap(thats why I replaced them). My check engine light was on since before the high water incident, I just never got around to checking it(yea I know, dumb move). Today I borrowed a scan tool and got back 2 codes P403, and P421. I looked the codes up: P403 Exhaust Gas Recirculation Circuit Malfunction and P421 Warm up catalyst efficiency below threshold. Tomorrow I'm going to test the EGR Solenoid and the O2 sensors, could this be causing my problems? What else could it be or what else should I check?

Response From speed

could his problem with starting be trouble with the starter not engaging or the distributor?

Response From Sidom

If the starter wasn't engaging it would be a no crank condition.

As far as the dist, that could definitely be a problem but I've found it's sometimes best to eliminate the easiest & cheapest stuff 1st....... A throttle body cleaning is really something that needs to be done whether you are having problems or not.....

Response From speed

thanks for giving me info also im still learing lots of stuff as im still in school but hope to be a mechanic
the only reason i always think of starters is cuz i thought thats where the spark comes from to the distributor even and then to the plugs? would you correct me cuz the way you say its not the situation

Response From lesonli Top Rated Answer

spark is generated from the ignition coil, goes into the distributor and, as the rotor turns inside, the spark is distributed to each plug. Some cars have no distributors just high energy coils and a thing we call pcm or computers put simply. And some cars don't have starters, they have cranks, big hills, or in my case, rubberbands. just messin w/ya

Response From Sidom

If you are just have this problem at idle I would start off with some maintenance. Clean the throttle body with some throttle body cleaner and a little brush (be sure to open the throttle all the way), then run it & give it some shots down the throat to see if that helps it idle a little better.

The 2 codes you got really should be causing your problem, the cat code is just the cat taking too long to set off, probably on it's way out and while an egr problem could cause some of those conditions, I have seen this problem on Mits, more than likely just a position sensor but and easy check would be to disconnect the valve while it's running good & see if the problem disappears....
