PCM's do rarely go bad, but it usually is a no-start when they do. Clear it and see during what conditions it comes back. It is a code where there is probably a threshold value, so you can't really pinpoint when it happens unless you have a cheap little scanner plugged in and see when you get a pending code, or freeze frame codes. Unfortunately it's one of those stupid vague codes that could be many things. It could likely be a random ass code, however if it's happened frequently enough to set the check engine light.
How do your grounds look? Always worth cleaning your grounds. The battery ground goes to the chassis, then to the tranny, there is one on the passenger side near alternator, and a couple other ones coming out of the harness and grounding on the core support.
