Is your 1998 Chevrolet Venture or other compatible GM vehicle suffering from perplexing engine issues? A faulty Powertrain Control Module (PCM) is often the culprit behind problems like a persistent check engine light, poor fuel economy, erratic shifting, or even a no-start condition. The PCM is the central computer of your vehicle, managing everything from fuel injection and ignition timing to transmission shift points. When it fails, the entire system’s performance suffers. This replacement Powertrain Control Module, service number 9357034, is the definitive solution to restore your vehicle’s original performance and reliability.
We take the guesswork and hassle out of the replacement process. Unlike a generic module from a parts store or salvage yard, this unit is specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN). This critical step ensures that the module has the correct software and calibrations for your specific engine, transmission, and emissions equipment. By providing us with your VIN after purchase, you receive a part that is ready for installation right out of the box, eliminating the need for an expensive trip to the dealership for programming.

Before replacing your PCM, it’s a wise diagnostic step to verify all power and ground connections to the module. A corroded ground wire or a loose connection at the battery terminal can mimic PCM failure symptoms. Use a multimeter to check for stable voltage at the PCM connector pins and ensure all ground straps from the engine to the chassis are clean and tight. This can save you from replacing a perfectly good part.
