I have my cars PCM computer with a faulty ignition circuit. It is a 4 cylinder engine, and there are two output pins that fire two coils for four cylinders.
I have located two MOSFETS on the board. I suspect its a MOSFET or a smaller IC further back up the line.
1. What is the likely hood of the fet working most of the time and then every few seconds faulting.? ( there is no bad burnt smell or any obvious signs of failure on the board)
2. What is the chance that it may be an ic further up the line that is faulty?
Also the MOSFET is a 52887. Can not seem to find a spec sheet on it.
