Well, couple of days ago I came right here with a 1391 code (often the computer cannot see the camera or crank shaft sensing unit setting) but ultimately it was not one of them however the ECU Computer and I need to change it. I Called the dealership as well as it costs 634$ CAD + taxes so concerning 735 canadian bucks. There are a lot of premises in the gas shot as well as computer system wiring harnesses because of this. Check Engine lights can be found in orange, yellow or amber, depending on the supplier. Each sensing unit as well as every device controlled by the computer system needs a great ground.
I talked to my dealership yesterday, as well as they informed me GM put out a bullitin on cng cavaliers up throught 1999 to place a boot over the computer. When a modification is done on one of our autos, the program that the ECU was running ends up contravening exactly what is currently taking place in the engine.
Ultimately, if the Breakdown Indicator or Check Engine light comes back on after the PCM has been changed, it suggests there's still an issue with the lorry - not the PCM (thinking the code is not one for an internal PCM fault, in which instance the PCM would be saying it is damaged).
A damaged ECU can trigger issues when shifting gears in a transmission, or cause sudden jerking or stopping that resembles transmission issues. The spark inc plug seals the combustion chamber and also gives a gab for a trigger to jump across and also initiates burning in your engine.
