Restore Your Truck’s Performance and Reliability
Is your 2002 GMC Envoy, Chevy Trailblazer, or Oldsmobile Bravada giving you headaches? If you’re dealing with frustrating issues like sudden stalling, a rough or unpredictable idle, poor fuel mileage, or a Check Engine Light that just won’t go away, a failing Powertrain Control Module (PCM) is often the culprit. Don’t let a faulty engine computer keep your reliable SUV off the road. This is the direct, professional-grade solution to get your vehicle running smoothly and efficiently again, restoring the performance you depend on.

- Engine stalling or cutting out while driving

Expert Insight from the Garage
After more than two decades working on these trucks, I’ve seen countless owners chase their tails replacing sensors and parts, only to find the root problem was the PCM all along. A common mistake is buying a used computer from a salvage yard. While it might seem cheaper, those units are not programmed for your specific vehicle and its options. This leads to anti-theft system lockouts, transmission issues, and persistent error codes. Getting a professionally programmed 2002 GMC Envoy PCM from the start is the single most effective way to ensure a correct and lasting repair, saving you from future headaches and wasted money.
Frequently Asked Questions
Is this PCM truly plug-and-play?
Yes, for the most part. We program the module to your vehicle’s VIN before shipping, which handles all the complex software calibration. Once installed, you may need to perform a simple security relearn procedure (often called a VATS or Passlock relearn), which takes about 30 minutes and does not require any special tools. We can provide instructions for this simple process.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program and ship your part without it. You can find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard visible through the windshield.
Will this computer fit my 2002 Chevy Trailblazer?
Absolutely. This PCM is compatible with the 2002 GMC Envoy, Envoy XL, Chevrolet Trailblazer, Trailblazer EXT, and Oldsmobile Bravada, as long as your original part number is listed. The internal software is what matters, and we program it specifically for your make and model using your VIN.
Will this fix my specific check engine light codes?
This programmed 2002 GMC Envoy PCM is the direct solution for internal processor failure codes like P0601 and P0606. It can also resolve a wide range of other codes that are triggered by a faulty computer. However, it is always best to have your vehicle properly diagnosed to ensure the PCM is the source of the problem and not a separate sensor or wiring issue.
What if I order the wrong part?
We strongly recommend matching one of the part numbers listed (19210066, 12571178, 12576463, etc.) from your original computer. By providing us with your VIN, we perform an additional check to ensure you receive the correct, compatible hardware for your vehicle, minimizing the chance of errors.
