Is Your Work Van Letting You Down?
If you’re driving a 1999-2002 Chevy Express 2500, you know it’s a workhorse. But when the Powertrain Control Module (PCM) starts to fail, that reliable workhorse can become a major headache. Are you experiencing strange, intermittent issues like stalling at stoplights, harsh or delayed transmission shifts, a persistent check engine light, or even a no-start condition that leaves you stranded? These aren’t just minor annoyances; they’re classic signs of a failing PCM, the central computer of your vehicle.
Real-World Diagnosis: The Ghost in the Machine
“A customer’s 2001 Express 2500 came into my shop last month with a problem that was driving him crazy. It would run fine for days, then suddenly start shifting hard and the engine would stumble. He’d already replaced the throttle position sensor and the mass airflow sensor, but the problems persisted. After hooking up my high-level scanner, I noticed the data stream from the PCM was dropping out intermittently. This is a textbook case of internal circuit board failure, often caused by years of heat and vibration. We replaced his PCM with one of our pre-programmed units, and the van has been running perfectly ever since. It wasn’t a bad sensor; it was the brain telling the sensors the wrong thing.”
