Excellent video -- Thanks!

12 years later this has saved me. THANK YOU !

🙏🏾🙏🏾🙏🏾

Is the first connextor on the header for the voltage regulator side a ground?

My 96 XJ keeps randomly dying. Gonna have to try this! TY.

Good work dud. Thanks a bunch for the insights , knowledge is wisdom.....thanks dud

THANK YOU SO MUCH! This fixed it. I soldered in those few spots and put it back together. you saved me 300 dollars for a new one! Just a bad solder can ruin everything.

I started to pour boiling water on my PCM and it starts up every time

Ive been trying to fix my 1996 jeep grand cherokee 4.0 for about 6 months now I've replaced the crank shaft sensor, cam shaft sensor, ignition coil, purge valve, fuel filter, idle air valve, and a full tune up. It runs like a champ but just dies sometimes at random times like at an idle, driving straight, turning. If im going over 40 most of the time it will back fire then die. Then normally takes a little while to get running again once I was stuck for 30 minutes. Im not very knowledgeable in mechanics and everything I have done has been from videos and reading forms. This was kinda my last resort but I got hit with a foot of snow so this morning I tried this method as well as shorting the screws, something I saw on another video, and it fired right up! Just took it to the mountains for a 2 hour snow romp. I could not have had the confidence with out this detailed video thank you.

I really hope this is my problem. I bought a 96 limited 5.2L for my stepdaughter because she wanted a 4wd SUV. It's been nothing but problems since. I drive it no issues she drives it and it randomly starts backfiring, chugging as she says and has no power. Then I drive it again all good! New alternator 2 year old battery and system tests good but sometimes it says good battery - recharge. I'm assuming the pcm voltage regulator is randomly disconnecting. Ordered new computer before seeing this video but for $200 I'm hoping this fixes it.

Got a 2012 dodge advenger I put a voltage regulator on car to by pass the charging system to computer.Still have problems and cant get new pcm for it.The part is obsolete. What do I need to do.

thank you so much for the info I have a 2002 Jeep Grand Cherokee Laredo every things fine when driving But when jeep is in park about a minute goes by it stalls out Starts right back up after though

Thank you sir!

HEY JEEPERS,, WOULD THIS BE THE SAME FOR A WRANGLER 4 CYL ? THANKS!!

Thanks man. Haave a 98 Jeep Grand Cherokee I tried this and it seemed to work. Thanks for sharing your knowledge and saving me $$

2:57 On the left of the board in that shot is an IGBT that fires the ignition coil. It supplies a ground to the ignition coil to fire it and that ground is looped through a shunt resistor so the computer can see the current which is analyzed by the adc next to it.

What website did you buy the sensor from.

This worked on my 96 now runs like a top 4wd. Drove 835 miles from Oklahoma to Indiana. Averaged 18.5 mpg @ an average speed between 75 to 80 mph.

I have a 1997 Jeep ZJ 5.2 with a different PCM marked 417AB. I have no idea how to open this unit as it looks different than the one in the video.. Need help!

Great Job, I fixed the problem by using Electronics Cleaner spray (available at parts store) and spraying on all connections on the main cable. Did not have to remove it. remove all cables, spray both the Cable assembly connectors and also the pins inside the housing. Allow a good time to dry or blow out with air. The cleaner is an evaporant, so will dry quickly. plug everything back together and try it out. If this does not work, then maybe a connection internal is oxidized or broken as he indicates in the video. Folks....keep in mind this is just a deeper fix if the external sensors have been proven "OK".

I have been having this problem for a year!! I bought a cheap eBay sensor. I kept getting a misfire. Thank you!

great video - am gonna put the cheep (15$) one in but if i have trouble def gonna swap that out

I know this video is old but I really need a question answered. My PCM does not have that board in the back cover. Is an

dont do it yourself , my screw fell into the waiting transmission big 2x2 inch hole right above the top hope on the crankcase sensor . if you do it yourself you better have small hands on a good universal socket with a magnet. i couldnt get screw of my transmission makes a awful noise the repair made me have to contemplate selling my truck. i may do a video on it

How did your jeep start acting? I can drive it for about 30 mins then on acceleration I loose power an wants to stall when giving more acceleration . What do you suggest?

Dude, How did you soldering? its dificult for the dissipator.

I just did this solder trick myself on my 98 GC with the 4.0 and surprisingly it fired right up. Felt like doing a jig I was so thrilled but I'm sure the neighbors would have called the men with the straight jackets on me.

Where is the pcm at?

Good job man I know what took for before tear it apart

Wanting to know if there is a certain fuse I need to change that controls the lighter,and if so,where is it at?

What if the connector pad looks like it's peeling up? Ima splash some sodder around and hope for the best.

Thank you for the info. Good to know about the pins and magnet values.. Jeez though, I can find an aftermarket sensor for 15 bucks.. Mopar wants 80. Oh well. Get what you pay for.

My 96 jeep grand cherokee v6 4.0liter engine my jeep hiccups when its idling an when i put it in reverse then push on the break itll stall out but also when i start to drive it itll feel like itll start bucking i changed my ecu my spark plug wires an im stumped i cant figure it out does anyone have any fix to this problem???????????????????

hey i junt want to ask, i have a 96 jeep grand cherokee and i have a same problem, i need your help how to fix my ECU, i been try to fix but still not work's please help me

Thank you very much. This is a very helpful information about the PCM. Great video!

Hi all, A big THANKS to you all for posting your videos on UA-cam or your comments on the countless forums to help people out with their problems. I'm posting this to possibly help others out there that may need it, because I found that everyone had slightly different issues around the stalling problem. Mine was different also. I have a 1996 Jeep Cherokee that had a stalling issue. It's fixed now, but I'll let you briefly know what happened. My Jeep was fine when it was a cold or cool temperature but would always stall when it got to a normal heated operational temperature and stopped at lights or backed up traffic at idle. It wouldn't start for at least another 30 minutes until it had cooled enough. I then realised it was always in D-drive when it stalled, so I tried flicking it to neutral every time I was stopped and it wouldn't stall until I got to my destination and tried to start it straight away. Again i would have to wait for it to cool and then it would start. After stalling I checked the diagnosis codes by turning the ignition to the 2nd position 6 times and waiting for the codes to flash. That told me to replace the coolant temperature sensor, the crankshaft positon sensor, take it to a mechanic for diagnosis and the completed diagnosis code 55. I disconnected the ground battery terminal from battery and started with the cheapest of options which was the coolant temperature sensor. After replacing the coolant temperature sensor and connecting the battery, I then checked the stalling issue by driving around for an hour and leaving it in drive and it stalled and wouldn't start for 30 minutes. I then decided on the crankshaft option so I disconnected the ground battery terminal, changed the crankshaft position sensor and tested it also by driving around for an hour and leaving it in drive and it didn't stall. Problem fixed. I then checked the diagnosis codes again and no codes came up, besides the code for less than 50 key starts since the battery was last disconnected and the completed diagnosis code 55. Regards Kurtis

do you remove sticker on bottom of sensor

What's a "pretty solid PCM" vs a not-so-solid PCM? If it's prone to failure, it's not solid!

Great vid, Thank's for the info, I appreciated the demo ,

Great Information. Thanks

katasztrofa a sok duma!!

The PCM on mine 1996 Grand Cherokee 5.2 has a different model PCM, this wont work for all the them

I have a 2000 jeep grand Cherokee 4.7 and my pcm is totally different than the one on this video

help guys how do we remove the glue the board is glued and im unnable to take it off

Thanks for the video and info. I think I'm going to pick up a spare at the yard before removing and cracking it open.

Gotta have some Ninja soldering skills for this, que no?

Thank you

Looking for info about the issue on my jeep I found your vid. I did the same welding on all the pins my jeep is been working with out dying for about 2 weeks now, now I have to replace the catalytic

WAIT A SEC,. HERE WHAT U MEAN BY A TEMPER RESISTANT SCREW.....? CAN U GET THEM OUT W/ A REGULAR SCREW DRIVER ( POWER OR NON POWER ... )....?

Awesome, man. I replaced the crank and cam sensor. $120. Then the alternator went out. $110. I have a 96 GCL. Ready to shoot it. It cut out on me last night 3 miles from home. Threw a P0351 for the coil. Pulled it back home and it cranked up. WTF? Saw your vid. Soldered all the connections. My turn signals work now. So does my horn-previously disconnected for alarm related issues? Running great now. Will update if change.
