Symptoms of a Failing ECM ECU PCM going bad (Failed Car Engine Control Module Explained U1000)

[@anitahendrix7573]

Yup!!! My 2017 suburban had at first a lot of life's go on the panel took to a local mechanic and he fixed some chewed wires and connectors. Seemed to be OK for two days then wouldn't start had it towed to dealer had more chewed wires and it must have blown out the PCM they fixed all and it is now fine. Found out it was rabbits chewing so put a fence around car. So far so good.

[@CARoutszong]

This was amazing! Thank you for taking the time to throughly explain it all.

Just had to order a plug snd play ecm from solo auto ecm in Miami. I had no wide open throttle after 2nd. Many new sensors with replaced harnesses were reading very high. The transmission computer couldn't communicate with the ecm.. new one came in today for a pt cruiser with a summit racing built motor and high performance built a604 transmission

[@both90]

Everything going on with my durango is pointing to the tcm after i had cleaned old throttle body and then change to a new one.. only thing that making me think other wise is the gage cluster turning off but radio and everything else working fine… does ecu control p Dash power too?

[@santogironmoreno6670]

Brother thank you for your explanation I appreciate

[@Airsoftfrreak96]

I am taking a shot in the dark and just assume i have a bad ECU. I have replaced all ignition related parts and now the car runs fine and in closed loop, but the same two codes keep popping up, no matter how many times i erase them. P0321 and P1361 on my 95 park avenue. It took me a month to come up with a way to diagnose the car, finally i found TunerProRT and made a homemade aldl 16 pin cable. Its really hard to get this car diagnosed here in Spain as no one knows what a buick is

I have a 2015 Nissan Versa Note that was throwing a P0138 (Bank 1 Sensor 2 High Voltage) and check engine light. The exhaust system was old, rusted and leaking everywhere. I replace the entire exhaust system (intake manifold back) except I didn't replace the o2 sensors (yeah pretty dumb I know) and the P0138 & CE light did not go away. With the new exhaust system, I tested the downstream o2 sensor and got poor readings (showing it was bad), so I replaced it and the P0138 code went away. But after testing the old o2 sensor/wiring & replacing the o2 sensor, the car wouldn't start (it turned over but would not fire up). I found a blown 20A fuse marked 'ECM' in the engine compartment fuse box (next to the battery), replaced it and the car fired right up, but it still shows CE light and U0100. The car runs fine so what could be causing the U0100 code?

[@Chunographx]

Great breakdown and explanation of ECM , I’m having trouble with starting the engine, of a Chevy 2012 equinox, my scanner says #78E then beneath that it says 78a and 78b I looked it up and it has something to do with relays and fuses, do you have a video or can you make a video on this code no other video makes sense to me

[@Ricky07070909]

Interesting to know all this! Do you t hink after a timing belt change (and cleanup), that why would an error "83 ECU Failure information: PGM-FI Relation Failure" suddenly appear? battery has almost 4 years too.. I've been scratching my head on this one and can't find the answer..

[@Chunographx]

He doesn’t reply to any questions 😢 i scrolled through comments and I found nothing

[@Shukura496]

Hi thanks for your videos. I having issues with my 2023 honda civic, Cluster blackout and engine cranking but not running... checked all fuses and all good... any idea what should i check??? Thanks

[@ruizrandyrr]

Would that cause the car to have issues with acceleration bogg out then harsh shift with acceleration returning to normal and continuing

[@swimwithcoachraven1532]

One mechanic took out the oil pump and installed it that was how everything started. No power when riding and had all the symptoms. Egg smell, misfiring and the jerk. Then after mechanics took out the transmission clean some parts and put it back it fired up like a new machine. 6 months later it happened again. Now it at limp mode. Hopefully it’s the ecu as I have only tried changing position sensor and the air intake control module

[@GerardHamusonde]

5:32 I have 3s engine releasing fuel on all the four injectors at once without following the firing order. Am stuck.

[@LeahWanga-ki5xk]

Where are u located I have ford figo 2012 model with same problem

[@Mishka_DaHusky]

Mine gives no codes at all, bad surging issues under engine load, bad fuel economy, random misfires. But the no codes cost me thousands in repairs before I knew it what my ecm

[@cognac8297]

Did you fix it

[@rec1015]

I got the same problem with mine, and no codes also. How did you find out that it was the ECM?

[@cognac8297]

@rec1015 it was always the map sensor.

[@rampage_45]

My wife's Nissan went into limp mode. The following lights are: Check Engine, TCS, SLIP. The following codes are: P2138, P0653, P0451 and P1726. The Nissan dealership stated that it was the catalytic converter, however Firestone stated that it was the ECM. Need some advice my man.....

Comprehensive list of admissible faulty situations that could fry a pcm.

[@WitnesstothefaithnMD]

my 2006 ford focus starts hard only at the first start of the day - it sputters and may stall. Subsequent starts are fine though.Could this be an ECM issue?We've checked fuel pump, cleaned injectors and spark plugs were recently replaced. the check engine light is persistently on regardless of fixing the issue the codes were indicating last year.

[@iceman997799]

I got no check eng light on but have 40 codes I wipe the codes and they come back right away. Eng does start but takes it a few key turns to get it to start and runs rough at idle. I have checked all the connections but thinking due to the computer saying injector1-4 have no signal but the eng is running. 2000 grand am 2.4L

[@Fran-yg4jp]

Can a bad ECU cause 02 errors, misfires, and black smoke out of exhaust when stomp on accelerator, and would it cause rich to lean ?

[@shaunDmond]

fran did you find out if it was it? i have the same issues

[@Fran-yg4jp]

@@shaunDmond I almost sure it is my o2's I proved it by unplugging my 02 and all at 450 mv from scanner readings and also checking power and ground, I also checked with 02 plugged in 2 wires same color proper voltage coming to 02 sensors. I also got a a lot of good information from Scanner Danner. He has a lot of really good videos and excellent forum. nothing against anyone on this channel , just really god information from Scanner Danner

[@jaedonwolf]

That sounds like bad catalytic converters

[@MrEdtheraiderfan]

I have a 2006 MBZ s500 and my car stalls while driving. Sometimes it will not start up, especially when it's hot out. There are no codes when it happens. I was running live data one time with my scanner and the car stalled and no code popped up. Could that be my ecu?

[@bigbusiness6903]

2012 Ram 2500 ST, Crew Cab 4 Full-Size Doors, Four-Wheel Drive, 5.7L V8 Gas- where can I buy the ECM ECU PCM ?? Which one is used in my truck ? And where is it located?

[@ekrikakemebradikumor7331]

I got it. ❤

[@Mya9268]

I have a 2014 Ford Escape I have to jump it everyday with a portable Jumstart box it’ll drive fine then I turn it off let it sit for 4 hours and it dies again ! Lights don’t turn on nothing it’s completely dead just got a new battery last week so it’s not the battery and when I turn my car off it says system off to save battery please help me someone please !!!!!!!!

[@destonsmith8618]

98 Ford mustang 3.8. Snan tool reading ECT 165 cold. New sensor still same problem.

[@Top5AutoRepairs]

Engine running cold possibly due to stuck open thermostat or cooling fan running all the time.

I need ur help

[@jomarfernandez1483]

I got an p0207 circuit open on cylinder 7 but i only got a 4 cylinder engine how did that happen?

[@Hardcorediver44]

My 2006 Saturn Vue 3.5 shows no codes. But the car will crank but not start. It's happened 4 times. Prior to this there was one night the wife came home and the engine bay smelled of burned electrical. There are no codes. The car will just randomly not start.

[@walterhawes7217]

Thank you!

[@camlobesvtec]

I have an Acura on e85 with the tank topped off. Sat for a little over a month, made sure positive and negative were connected properly. Tried to jump it and would not start. Starter is working , but no fuel pump sound. The battery was completely dead when I tried to jump start it. Fuel pump and ecm fuses are good plus new battery. Please help, any input would help. Trouble code was P1035 . HHEEEEEELLLPP!!!! LOL

[@Elcompa452]

Get a new ecm

[@mkultravibes7763]

Mine was fine until I drove over a large puddle of water . Could this be the cause .2012 Camry

[@Blazerows]

Same with mine but I was able to drive about 1 hour afterwards. Then drove the next day. The day after that it died. Started and stalled and shacked fairly hard. Then intermittently cranking and fuel pump continuously running. And no communication with the obd2 port. I think it could be pcm but anything is possible

[@tyrachel]

Great

[@chvnse]

so here is my issue, my maf code came up and then went away and then i was having misfires, they come and go, when at a light or stop sign the van will surge, and now today all my dash lights are on and flickering. Would it be correct to think my ecm is bad?

[@robo9466]

yo having same issue currently lmk what u found out bro

[@ronaldrovnazaire3250]

Well I have an infinity G25. It won't start the lights turn on the headlights nothing else come on. Is it that the BCM?

[@mcdonaldmotorsportsmcdonal9056]

I have 13” G37 doing the same thing no crank no rotation just clicks? Headlights work wipers stereo etc

[@damonhymel4746]

Could a bad PCM cause the fuse to blow? I have all these issues besides the codes, but sometimes it blows the fuse too

[@Top5AutoRepairs]

Yes if there is a short

[@rolandorodriguez8359]

Mine come with all lights in the dash board come on including the eyesight light the codes p2004 p2005 I erase them and they come back

[@01..........]

I have a c0298 P1120 Wire was damaged and replaced. I erased codes works fine. I turn off vehicle and the codes will appear again.. I erased codes again. Works perfectly. Turn off and back on again and codes reaper

[@netteJulia-kt4ki]

i have ecm code but literally it's been on for months and no problems i drive it back and forth an hour to work an hour home

[@rogerlittreal642]

took my car to meineke. they wanted $2700. I bought the part online for $260 and a dealer to install for $300. be careful.

[@rogeliorosales5073]

Mine is trowing codepo300 and my spark plugs smell like gas
