pcm

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 /...

Hello all. I wanted to gauge opinions. I had some issues a year ago where the jeep just wouldn't crank (turn key, nothing happened). I thought it was the starter, which I replaced but it continued happening. Then within the last few weeks my jeep started stalling randomly. It only happens after...

I've had my 99 Sport torn apart for about 4 months with no battery. I did the big 3 upgrade, a stereo install, fixed some broken wires and replaced my oil sending unit. If you recall i was also the one that had the PCM willed with oil. I washed it with alcohol and let it dry for a few days. and...

@Igoo65, @Jerry Bransford, whomever else...- I would PM you about this thread but I don't see that feature on this forum. YES, I've read through numerous posts here and on other forums. My situation seems to be bit different, I've tried to provide exhaustive data up front so someone can "walk...

Hi, I'll try to keep this short. Last June (2019), my tj started having some issues starting here and there, but each time it would eventually start after trying 3-5 times and/or waiting 10-15 minutes. The mechanic I had look at it at the time said that the fuel pump and filter were about to go...

It is frustrating that the TJ is so vulnerable to problems with its 'computer'. It seems to me that a computer represents the antithesis of what a Jeep is supposed to be. Rugged, utilitarian, able to be repaired in the field with blood, sweat and duct tape. I would like to be able to brag that...

Good day! New to the forum and I have seen a lot of great information posted here. My wife has a 2006 LJ auto with the 42RLE with about 111,000 miles on it. The check engine light came on yesterday after it got started and had a strange idle. got the P1604 code from the self diagnosing we are...

Gales Banks Power has discontinued the Sidewinder turbo kit. Bank's states they will continue to offer tech and parts support. Source inside Banks states that the pre-2005 installations were having trouble passing smog tests and could require new programing and/or equipment along with CARB...

I know that many Jeep TJ owners have seen my automotive YouTube Ozzstar videos on air conditioning repair, rear axle differential, shocks and transmission shifting issues. I would like to simplify the hard shifting problem that the '05-'06 model can experience. Trouble codes such as P1603...

Hey I just received a brand new PCM for our 2005 Jeep Wrangler Sport Got it from Wranglerfix in Florida Very very Happy with the part!!! Jeep runs smoother and shifts smoother!! Mark from Wranglerfix talks to you personally He literally talked to me for an hour about my TJ Very very happy!!!

I hooked an older battery charger up to my Jeep. I tried to start it with the charger still on. The whole Jeep hummed like a swarm of bees. I fried the PMC-ECU. I took me forever to find the right computer for my '97. I put the new one on. The Jeep would turn over and stay running for a second...
