Is Your GM Truck or SUV Acting Up? It Could Be The Brains of the Operation.
If you’re dealing with a 2001-2002 Sierra 1500 that’s developed a mind of its ownโstalling for no reason, shifting erratically, or throwing a confusing array of check engine light codesโyou’re likely getting frustrated. You’ve probably checked the battery, tested sensors, and maybe even considered a fuel pump. But often, the real culprit is the one component orchestrating everything: the Powertrain Control Module (PCM).
As the central computer for your engine and transmission, a failing PCM can cause some of the most baffling and intermittent issues I see in my shop. After two decades of diagnosing these vehicles, the symptoms become second nature, but for an owner, it can be a nightmare.
Common Symptoms of a Failing GM PCM
A faulty PCM doesn’t always fail completely. It often starts with small, annoying problems that grow worse over time. If your vehicle is experiencing any of the following, your PCM is a primary suspect:
- โ Unexplained Check Engine Light (CEL) illumination
- โ Engine stalling, stumbling, or rough idling
- โ Harsh or delayed transmission shifting
- โ Complete no-start or intermittent starting condition
- โ Loss of communication with your OBD-II scan tool
- โ Multiple unrelated diagnostic trouble codes (DTCs)
- โ Poor fuel economy
