p0132 p0138 & P0121
Went through the answers. Still having problems.
The problem started with my 2000 TJ 4.0 (German model) running rough sometimes when warmed up.
Received p0138 and p0132. Replaces both O2 sensors by Bosch universal parts.
Problem still there. A mechanics in FL recommended to change the TPS. After I changed it I also got a P0121. First I thought the part might be broken. Changed it a second time P0121 still there. With the old TPS I still get P0138 and 0132 but no P0121.
The problem of running rough got worse with the new TPS.
Now we will go into the wiring. Any recommendations?

|csala027||Oh ok, well thank you , you saved me about 30 bucks. I can buy the part for 25 bucks and a guy said for 50 he can install it for me|
|09-26-2013 01:55 PM|
why what? the socket? it can be done with a 7/8 wrench and no need for it.
|09-26-2013 01:48 PM|
|csala027||May I ask why? Sorry I'm new, trying to learn everything I can.|

|Big Sarge||If only one is bad that is fine. you do not need the socket. I personally think they are a huge waste of money.|

It's 25 for the ntk brand do I need to buy a socket as well?
Also I can afford to install 1 o2 sensor and my jeep is a v6 is that ok? Or do I need to change our both sensors?
|09-26-2013 01:32 PM|
rockauto is the cheapest, price sounds off though!! Make sure that you use the NTK brand or you will experience problems. I have a thread that was moved to the general discussion area that has a discount code for rockauto.
|09-26-2013 01:29 PM|
|csala027||Know a cheap place to buy the part? Rock auto is 22 and AutoZone is 40.|

|csala027||is the o2 sensor bank 1 sensor 1 an upstream?|

OK, been following these threads replaced my 02 sensor, bank on, sensor 2 per the PO138 code according to the diagram above. The Check engine light went out, it does seem to be running better, but still feels like running on 5.5 cylinders. This is a new 4.0 crate engine in a 2000 TJ. Without a CE light I'm not pulling any codes, so I'm wondering if it just needs miles to clear up, or how to find whats causing the continued problem

Ready to change downstram o2 sensor, but it's too tight 0.o
Hey thanks a lot for your helps guys, I changed my o2 sensor, just need the downstream one now.

|homiegx||I went and got the socket. Came off easy with it. Old one def looked spent.|

If you have heard of any that have bent, they were of incredible poor quality. It may be cheaper in the long run to buy a quality O2 sensor socket. If you damage the sensor you may need to being it to a shop so they can get it out for you. Plus if you have it and have another sensor crap out on you, you're set.
I'd let you borrow one of mine if you lived close by.

|homiegx||Yes bank 1 sensor 2 is one I'm trying to replace but the wrench won't slide on the sensor with the space that is available to turn the wrench between the skid plate and the muffler|

I went from the bottom. You were talking about downstream sensors right? Crawl under behind the front tire and look up and you can see both downstream sensors.
The one closest to you is Bank 2, Sensor 2. Closest to front bumper is bank 1, sensor 2.
I had to change bank 2 sensor 2. It was still tight. I could only get 1/4 turn at a time, if that, but eventually it came loose.
Haven't tried to get at bank 1 sensor 2 yet, but I would think go underneath in front of the front tire. It was more on the foreward side of the cat if I remember.

I ended up having to put an adjustable wrench on it. If you happen to have an open end that is the right size, this would be preferable to an adjustable.
Also you should be able to get a specialized wrench at autozone or something. It looks like a closed end wrench, but with a slot in the end so you can slide it over the wires.
Either way though, you might save yourself some trouble by spraying some break free on it first and letting it soak for a while before you try to unscrew it. Those things get seized up and take a lot of force to get them going, last thing you want to do is break it.

Please tell me,
-Were there any pre-failure signs?
-Were you getting more than 13 mpg
-What are you getting now?
-Did your fuel economy increase?

|homiegx||Ran into a little snag, how did y'all change the sensor after the cat? I can't seem to get the wrench to fit over the ridges on the sensor with the space that is given between the skid plate and the muffler?|
|04-10-2013 05:51 PM|
|homiegx||Thanks for info. Was about to just leave it over night from what I've read somewhere else|
|04-10-2013 05:50 PM|
|homiegx||Ok thank you|

|viperx6x9x||I am not sure how long to disconnect the battery exactly, but it will clear the codes. I just took mine to advance auto. they are not allowed to clear it for you, but you can check out the reader from them and do it yourself. Not very difficult. Plug it into the OBD2 port, turn your key to accessory, and follow the menu's.|
|04-10-2013 07:29 AM|
|homiegx||I'm about to change my O2 sensor. The CEL was off, I have read that disconnecting battery for like 30 minutes will wipe code is that correct or do I have to take to auto store and have them wipe it?|
|03-29-2013 03:33 AM|
I had a different O2 code, I will have to dig up the number when i get home. But the code printout said "Heater Condition sensor 2". The weird thing is the light was on for 2 days, and then went away before I had a chance to start troubleshooting. It has been a few days now and it hasn't come back. If it's the downsteam sensor, either the sensor is bad or the cat is bad right? But if the cat was bad then the CEL wouldn't just go away you would think. Loose connection on the downstream sensor maybe?
Somebody mentioned the crank shaft sensor, can that be related in any way? The PO said he heard a ticking noise (i have yet to hear it myself yet) and the mechanic said it was the crank shaft sensor.

|03-28-2013 05:08 PM|
|homiegx||But even if the ECU is stuck In loop when the light is off which I'm assuming the o2 sensor is working during that point, how would a new one get it out of the loop?|
