Is Your GM Truck or Van Running Rough?
If your 2001-2002 GMC 3500, or another compatible GM vehicle, is suffering from inconsistent performance, a persistent check engine light, or other frustrating electronic issues, a failing Powertrain Control Module (PCM) could be the culprit. As the central computer for your engine and transmission, the PCM is responsible for managing everything from fuel injection and ignition timing to transmission shift points. When it fails, the symptoms can be widespread and difficult to diagnose, often leading to wasted time and money replacing perfectly good sensors.
From the Diagnostic Bay
We once had a 2002 Silverado 2500 in the shop that had its owner pulling his hair out. The truck would randomly stall at red lights and had a terrible hesitation under acceleration. The owner had already replaced the throttle position sensor, mass airflow sensor, and even the fuel pump based on various forum suggestions. After hooking up our scanner and seeing erratic data streams that made no sense, we suspected the PCM. We swapped in a pre-programmed module, and the truck immediately ran like it just rolled off the factory floor. It’s a classic case where the ‘brain’ was the problem, not the parts it was controlling.
Symptoms of a Failing Powertrain Control Module
- ✔ Persistent Check Engine Light (CEL) with various or no specific codes.
- ✔ Engine stalling, stumbling, or hesitating unexpectedly.
- ✔ Rough idling or misfires.
- ✔ Poor fuel economy.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass emissions testing.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
