o2 sensor on '95 jeep

Showing 4 out of 4 Posts
Question From completelyhis on o2 sensor on '95 jeep

My o2 sensor on my '95 jeep keeps faulting. when i hook up the code reader it says something about high voltage something or other (sorry, don't have the code reader with me, and my memory is worthless).

i replaced the sensor, but it keeps happening. any suggestions as to what to look for?

Response From way2old

See if you can get the exact code numbers and post back. There are too many variables on the O2 sensors. Vacuum leaks, too much fuel, not enough fuel, exhaust leak, exhaust restrictions, MAF or MAP reading wrong, bad wiring, bad connections. These are just a few of the things that can cause an O2 code.

Response From completelyhis Top Rated Answer

The exact code is

21
Oxygen sensor bank 1 position 1 shorted to high voltage


I just replaced this sensor about 2 weeks prior to the code showing up. I notice a foul smell in the exhaust, plus it seems to be putting out a nasty blackness (dang, new muffler and cat. conv too!!)

The check engine light comes on/off intermittantly, the engine runs much worse when the check engine light is on, so I do think it is a "real" problem.

Response From dave284

JUST A NOTE , I HAD A KIA WITH SAME PROBLEM AFTER REPLACING 02 SENSOR THIRD TIME , I REALIZED SOME OF THE AFTER MARKET PARTS DON'T WORK ,THE OEM DID THE TRICK

Question From EMT418 on 94 Jeep won't stay running

94 Jeep won't stay running Edit | Quote | Reply a 94 Jeep Grand Cherokee sport is giving me a headache. I have checked and tried everything. It will start and run for about 2 minutes then spit and sputter and shut off. It will crank over, but will not start until it sits for awhile and then it will shut off again. I have spark, I have 40 psi fuel pressure, I changed the rotor and distrib cap. Any help?

Response From kiefer Top Rated Answer

hmm hows your compression?... your cold start injector could be sticking open or your o2 sensor is plugged up and giving a rich reading to your ecu once it comes of the loop relay and checks the sensors?

Question From Guest on code for jeep liberty

2006 jeep liberty, 3.7engine, 87,000miles

check engine light went but now is off.

just pulled code p2098 can anyone tell me what this is.



thanks john

Response From Hammer Time Top Rated Answer

I had a Chrysler vehicle not long ago with that code that drove me crazy. The first think to look at is the downstream O/2 sensor itself. If the sensor is not the problem, then the exhaust system has to be examined very closely. Chrysler has an internal memo about cracks in the catalytic converter that causes this code. They tend to split right along the seam weld but you have to look very closely and possible pressurize the exhaust system to find it.

Response From Guest

thanks for the replies, where would the downstream o2 sensor be located. also now that the check engine light went off could this have been just a hiccup, or is there a problem.

thanks again guys

Response From Hammer Time

There are no such things as hiccups in computer systems. The problem occurred at one time and will likely occur again.

The sensor in question here is marked #4 in the pic.

Response From Guest

thanks for the very detailed responses
greatly appreciated.....john

Response From Sidom

In a nutshell that is a rear fuel trim lean code.......

That is a 2 trip fault code (meaning the vehicle has to be driven twice under the corrrect conditions to set)

Three passing trips will turn the light off by itself but code will be stored........

Jeep Mystery Starting Problem

Showing 2 out of 9 Posts | Show 7 Hidden Posts
Question From mdelay on Jeep Mystery Starting Problem

1993 Jeep Grand Cherokee 4.0L Unsure on mileage.

Jeep is at the mechanic shop because it would not start. It had a split wire in the wiring harness. It has a new header, ignition coil, cps, distributor, fuel injectors, computer, and many other parts. Timing was off, but is now set. The mechanic is able to get it started only with the #1 spark plug out. Any ideas?

Response From nickwarner

Doesn't make much sense. Has he done a compression test yet?

Response From Hammer Time

I'd also look for something that may be causing crossfires like the firing order or cracked distributor cap.

Response From Discretesignals

Check for plugged exhaust system or cat? Maybe taking the plug out allows the exhaust gasses to pass through #1 exhaust valve. (WAG)

Response From mdelay

We bought it not running, the previous owner said he thought that it was a fuel problem. After having someone take a look at it, they discovered the ECU was not communicating to the car. Took it to the dealership to have it "flashed", since previous owner said he replaced it. They said it was not able to be flashed because it was bad. They replaced the Crank Sensor, and Distributor, and new ECU. It was running, but had a terrible exhaust leak. Didn't drive it because the leak was horrible. Got the header replaced, now it won't start again. Found wiring harness to have some wires melted together. Replaced wiring harness. Replaced the fuel injectors, new plugs, wires, ignition coil, new battery, and another Crank Sensor. Still nothing. Someone suggested the timing may have been thrown off. Had a new timing chain/belt put on it. Still nothing. Took it into the mechanic shop and found a wire in the wiring harness was not connected, but still nothing, ran a new ground (which he said helped).

Response From Hammer Time

Most likely that melted wiring is what ruined the first computer and may have done it again. Computers don't just die of old age, they are killed by something.

Response From mdelay Top Rated Answer

Final report is a clogged catalytic converter. Unplugged o2 sensor and it starts with # 1 plug in.

Response From Hammer Time

0/2 sensor Unplugged or removed?

Response From mdelay

Removed

Wet Weather Jeep Problem

Question From redlaredo on Wet Weather Jeep Problem

I have a 91 cherokee laredo, 260k+, 4.0, straight 6 automatic, 4wd. It runs fine outside a few quirks, but when there is a heavy rain or i drive through puddle, the engine will sputter for the next couple of hours. it will still run, but acceleration is difficult. any advice?

Response From Tom Greenleaf Top Rated Answer

The first likely problem items are the high voltage items like plugs, wires, cap, rotor and coil(s).. Sometimes you can see them "arcing" when dark or perhaps plain sight now. Note: The longer you run an engine that is misfiring for any reason the harder it is on you convert(s) up to killing them and o2 sensors,

T

Response From redlaredo

i dont understand...what plugs, wires, caps, rotars, coils are you talking about and what is wrong with them? what do you mean arcing? are you saying those things are getting wet and therefore causing some kind of problem?

Response From Tom Greenleaf

Electricity just naturally seeks the easiest way to ground. In car's ignition system the high voltage of the items metioned need to insulate that charge to fire the spark plugs. If it doesn't get there or leaks between any errantly it won't fire properly or sometimes at all.

All but about distilled water conducts electricity. Ever see the warnings about using electric things in or near water even at home?

Temporarily spraying some WD-40 (water displacement is what the WD stands for) can correct the problem especially in near invisable cracks or carbon traces on any of those parts.

The dampness could be affecting something else electrical. The most sensitive is the ignition and it's components,

T

Response From redlaredo

i appreciate your advice and insight, but im not really sure about what your telling me to do. just spray some wd40 on some stuff? spray it on what/where? if that is the temporary solution, whats the long term solution. if i wanted to take it off-road im afraid id have some trouble with it stalling and/or possibly dying after getting wet+

Response From Tom Greenleaf

WD-40 is a maybe for a temp fix and just might as it seems to correct when dry again.

You would spray on distributor cap, coil tower(s) and along spark plug wires. It's flammable so best done with cooler engine and don't aim at hot exhaust parts especially.

That is as old as the product by brand but sold as "wire drier" still I think under assorted brands. For the most part the brand WD-40 won't hurt anything - can't speak for others.

The fix is to replace the items that have the faults. No patch I know of will last,

T

Response From redlaredo

how do i know which part(s) are causing the problem?

Response From Tom Greenleaf

If it is jumping electricity out of a wire or between them or at the cap you may see it as a spark. When you have the problem you could just spray one item at a time and the one(s) that make it correct the problem should be replaced. If you find a plug wire that has a spot rubbing thru or something like that on a budget you can get just one wire.

The other way to find WHICH item is causing it is to spray plain salt (table) water on suspect parts when it's running well and the one(s) that make it repeat the problem may show right up for you.

It may not be the high voltage ignition stuff at all and could be wiring to some other sensor usually at a plug/connector that is weak or making a poor connection.

You said you can get this problem right away from hitting a puddle so anything that might get wet from that is highly suspect. Many vehciles won't wet the engine much or at all with ordinary puddles.

If you want my guess on which part right now I'd blame the distributor cap. They get hairline cracks sometimes from being shocked with cold water on a hot brittle plastic part and will behave when dry again and misbehave when wet again.

Note: Problems when moisture is the trigger are almost always electrical and not mechanical problems,
