pcm

Greetings, new member here. I have a 1997 TJ that I bought new in January of 1997. It now has about 125,000 miles and has always been a great and dependable vehicle. The other day I tried to start it and I noticed the the CEL did not come on when I turned the key but instead the Check Gauges...

2002 4.0 manual stalled while wife was driving ☹️. Fuel gauge shows empty and won’t restart. I was thinking fuel pump died. Engine spins when attempting to start. Dropped tank - still 1/2 full of gas. When I apply 12V to electric connector at tank, pump sprays gas. I checked continuity of power...

Starting a thread to discuss/investigate some intermittent engine stumbling/staggering issues I've noticed after I bought this TJ with regards to possible compatibility issues with having a PCM from a TJ with an Automatic As per @RMETeeJay 's suggestion I've started a new thread here to post...

Starting to get a bit frustrated with trouble-shooting so hoping maybe someone has come across a similar/same issue that may have a suggestion or two on anything else to test prior to opening up the wallet :-) Purchased a 2005 TJ SE, 4.0 back in december via facebook marketplace and issues...

I THINK THIS IS MY SECOND POST AND I HAVE BEEN LOOKING AROUND QUITE ABIT ABOUT THIS ON THIS FORUM AND OTHERS. I have 2005 Rubicon 2 door inline 6 100k miles had her since 2018 automatic 42rle been getting CA emissions 4 o2 sensors : Current Issue p0031 p0037 p0051 and p0057 . I had these...

I drive a Jeep TJ 2006, Auto Trans. So I have had my Jeep around 3 months in that time I have been fighting issues with my transmission / Limp Mode. (Maybe my PCM I was hoping @Wranglerfix might offer some advice.) So I after about 1 hour of driving at night much cooler on the downshift around...

Long shot but I have these parts from an 01 xj I parted out. Jeep ran well, It was a 4.0l automatic. Figured if someone here wanted to retrofit a SKIM system to their 00-01 xj they could find this useful. Not sure if it will work on TJs of the same year. Looking for $200 shipped or best offer.

So I believe I found my issue is that my pcm is wrong. My tj is an 02 and the pcm was out of an '00, it physically plugged in but was getting no bus. does anyone know if an 03 will work in my 02? Both jeep and pcm are non skim and I would only have to wait until tomorrow for this one rather...

Okay, I'm super new to this so bear with me... I have a 2003 Jeep Wrangler Sahara. Well, my daughter has. Anyhow, she launched a rod through the block. This was due to some problem that caused the check engine light to come on. Long story short... New motor is in and same problem: The Jeep...

1st Time Post-er, Having some trouble with my 2005 TJ, Automatic 4.0L. 66k miles on her, and has been running great until recently... Driving home one afternoon, cruising at 45 mph (2200RPM), all of sudden RPMs jump to 3000 and the ol' money indicator lamp turns on. She limps home, and that's...

So I have a friend who I'm trying to help out. So far I've replaced the oil pressure sender, but I don't believe that's the issue for as the single wire going into the white connector, not the black connector at the PCM. The black connector is where the oil is. The gray and white connectors are...

A few weeks after purchase, this Jeep just died while driving. None of the gauges would work, wouldn't crank, etc. Had PCM replaced and it worked fine for a bit. Then suddenly, it strands us in the middle of nowhere in the Bighorn Mountains of WY...and it acted just the same - died while...

Hey yall! This is my first post so any advise on a better post would be great! I’ve been roaming this forum since I’ve bought the jeep and it’s been great so I decided to make an account! Anyways, I bought a 05 lj a few months back and it has been a great experience so far. Just until I ran...

So i made a post about this last fall, but i haven't found the issue yet and it seems to be getting worse. Im currently getting code P0031, P0037, P0051, P0613, P0700, P1604. These are all 4 O2 sensor heater codes, two transmission controller codes, and a PCM code. I'm also getting occasional...

The following parts are from a 2000 TJ 4.0, Manual, 110,000 miles when removed. All parts were in great working order when removed, and stored in garage. If you have any questions, let me know. These parts are located in Eastern Washington and OBO. If you need an item shipped we can discuss...

I've got a 97 Tj 2.5l. I just swapped out my injectors to some 19lb four holes. Got everything installed, fired up and ran amazingly smooth. Went down the road and noticed after about a 1/4 throttle the jeep kind of fell on it's face. Seemed awfully sluggish. Would clear up and gain power as I...

My ecm blew and I can’t find a used one or a new one within an affordable price. Would a ECM ECU Engine Computer Unit 2006 Chrysler PT Cruiser M/T 2.4L | P05033427AG work? it’s the same engine and transmission and the ecm looks identical and even the plugs are the same. I just have no clue if...

My battery was showing low on the voltmeter after driving a while. I would recharge the battery and drive for half an hour and it would shoot back to about 9 again. I got the battery tested at O’Reillys and they said the battery was fine but the computer they used said that the volt regulator...

99 TJ 4.0 manual. I seem to be losing communication from the Cam sensor/distributor pick up to the ECU. The jeep dies when coming to a stop or once letting off the gas to stop. I lose all gauges and get the No Bus code on the dash. i tracked down the sensor causing the issue to the cam /...
