Expert Insight from the Shop Floor
“We see these late-90s GM trucks all the time. A classic symptom of a failing PCM is a cluster of seemingly unrelated trouble codes. The owner might replace an O2 sensor or a MAP sensor, but the light comes back. That’s because the computer itself is providing faulty data. Installing a fresh, correctly Programmed 09355699 PCM is like giving your engine a clean slate. It ensures the entire system—from fuel injectors to transmission solenoids—operates in perfect harmony, just like it did the day it left the factory.”
