i don't believe how that can even happen. its plugged in. even if you poured oil yourself over the connectors while its plugged in i would have a hard time believing it would get int here. so if you have an oil leak lets say, the chances that the oil flys around the engine bay and magically finds its way to the pcm, then INTO the the connectors it cant happen.
you would have to notice oil on the outside on the connectors for this to have any chance of happening.....do you?
i hope i dont come off as a dick, but i just cant wrap my brain our this.
