Signs & Symptoms of a Failing ECU/ECM! (Engine Control Unit or Engine Control Module)

[@GotitGamingCommentary]

Got a decently interesting story here. 2013 Ford Fusion se with a 1.6 cylinder SE. Brought car to ford dealer to get two tires replaced, they replaced the two tires and a wheel speed sensor they said was faulty. Fast forward a week, car throws 7 different codes while driving 30 mph on a two minute drive, Coolant overheat P1299, steering fault, abs/traction control fault, evap issue, U0131 and U1035. To try to fix the easiest first, I replaced the battery (5 years old) and the Coolant Temp Sensor, because online they said if there was coolant in the harness it could cause the short. Fast forwards another week, all the codes pop back up and it goes into limp again. At this point I brought it back top the dealership, they told me they think they need to replace the coolant temp sensor and the pigtail to the sensor. Which befuttled me because I just put a new one in a week ago. I called them to tell them this and they said it could be do to a cheap part (My part was OEM). Fast forward to this week, Traction contol/ABS error, P1450 EVAP, U1035 and U0131 popped up again. My thoughts are all bringing me to a computer issue because after I clear the codes, it runs smoothly for days and hundreds of miles. The car has been taken care of and hasn't had any issues since the Electric Steering Collum was replaced a year ago from failing. Any ideas would be great, thanks!

My 2012 Honda accord was diagnosed with the u1055 code ECM and the lights are popping up for the TCS, ABS and handbrake light. What do I check and have to fix, to get those light to go away? Can I drive, without issues?

[@monicatheshyone3985]

I’m driving the shit out of my car. There is nothing wrong with it, just the lights that are still on.

[@sierraproduction6581]

I believe my ecu/ecm is failing on my 18’ camaro throwing all those codes and giving a list of faulty sensors. Is it better to replace ecu first rather than going down the list and fixing all the list of codes? Ive replaced a couple of the codes like spark plugs, 2 ignition coils, and has fixed the misfires. now giving oil pressure fault sensor. And still idling rough

[@8020Media]

S - If it was up to us, we would change sensors first as they tend to be cheaper. Keep us updated.

[@OCtheG]

@@8020MediaCorrect! Bad signal input can kill an ECM, the hard faults should be rectified first before trashing a new computer with the same issues.

I was getting an electrical burnt smell in the car. With an ALT overcharging, this fried many things in the system.

Ive got 23 fault codes. 2017 vw golf tsi 1.4L Ranging from misfires in cylinders 1 and 2, starter motor issues (car starts fine first) As well as the steering angle sensor

I recently messed up my truck (2003 Silverado 1500) I connected my light bars positive wire to get power and connected it to my f/pmp relay and while I was doing it my truck shut off and ever since no crank , no start then I moved around the fuses and it starts but the dash doesn’t work and it says low power , when I go to turn off the truck it doesn’t turn off the engine keeps running for a minute then turns off . Any suggestions?

[@8020Media]

E - Are you getting any engine codes?

[@ericjimenez6886]

@@8020Media the dash wasn’t working I got my truck back to running good took it to the dealership

[@ericjimenez6886]

@@8020Media turns out the reason the truck didn’t want to crank and start was because I put to much pressure in the fuel lines and needed to bleed it out got it back from the dealership running but still electrical problems I checked under the hood and a ground was disconnected from the battery. I plugged it back in and good to go my fault for not noticing the obvious

I got a 91 Ford f350 7.5 i have replaced almost everything but it still misfires. Could my PCM be a problem?

my 1993 corvette is showing a code 44 that means 02 sensor or running lean. 02 sensor with many other items have been changed on this vehicle. To list would be to long, but I still get H44 code and the vehicle runs good. Sometimes on idle at red light a little rough and light will come on then the light will go off but vehicle runs good. Changed prom in ecm thinking that would help still showing H44 code. Some times on the idle runs fine sent the ECM out last winter to SAI Electronics in IL and they said there was no problem. Cannot figure why this code continues to come up H44 is left bank 02 sensor. Both have been changed along with the cats to new magna flow cats. Many other items have been changed on the vehicle but continue to get code 44 with check engine light. At wits end

My car engine runs just fine but in the last few years when I’ve gone out to start up it like misfires and the engine light is flashing becomes undrivable. I go inside wait 10 minutes and start it up and it runs just fine. It’s done like three or four times in the last few years.

D - Sorry to hear this.. Are you getting any engine codes?

[@jerryshadley8977]

Check your spark plug wires/boots for any damage if so replace them, also check your spark plugs for any noticeable damage an if there is replace them. If that doesn't work an ya have one on you use a scanner tool to try and see if any codes shows up.

For some reason the check engine light does not come on at all on my car, I have a ‘77 porsche 924 and it does not come on despite my car misfiring constantly. Cant even accelerate/ step on the gas without it misfiring and the car wants to cut off and is sputtering. Any ideas on what it could be?

[@8020Media]

Z - Have you checked for engine codes? This is usually the best place to start for diagnosing.

what would cause a fuel pump to shut off, i have a 2006 ford f150 4.6 it starts fine runs for like 2 minutes then idles down and stalls. the on board system tells me to check gauges, everything seems ok. then i try to star it from that point and it just cranks, no start, but if i turn the ign key to off and it will repeat the run and stall, i took the plug off the fuel pump driver module .and jumped the 2 outer wires and it starts and stays running. can not figure what is going on any suggestions!
