Is Your Truck or SUV Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than an unreliable vehicle. If your Envoy, Trailblazer, or Colorado is suffering from bizarre electrical issues, stalling unexpectedly, or simply won’t start, a failing Powertrain Control Module (PCM) is often the culprit. This critical component is the brain of your engine, and when it fails, it can cause a cascade of problems that are difficult to diagnose. Stop throwing parts at the problem and get the definitive solution that restores your vehicle’s dependability and performance.
Common Symptoms & Your Solution
A faulty engine computer can manifest in numerous ways. If you’re experiencing any of the following, this pre-programmed module is the solution you need:
- Persistent Check Engine Light (CEL) with communication-related codes (e.g., P0601, P0606).
- Engine stalling or cutting out while driving.
- Harsh or erratic shifting from the automatic transmission.
- Complete no-start condition where the engine cranks but won’t fire.
- Noticeable decrease in fuel economy and poor engine performance.
- Inability for a scan tool to communicate with the PCM.

Expert Insight: The Intermittent Stall Mystery
We once worked with a customer whose 2007 Trailblazer would stall randomly at red lights. Two different shops couldn’t find the issue because it never acted up for them. They suspected a fuel pump, then a sensor, but nothing worked. The real issue was the original PCM’s internal processor overheating. Once they installed our pre-programmed 2007-2008 Envoy PCM 19210067, the problem vanished instantly. It’s a classic example of how a faulty computer can mimic other mechanical failures, making a direct-fit, programmed solution the smartest repair.

Frequently Asked Questions
Do I need to have this computer programmed?
No. The main benefit of our service is that we program the unit for you before it ships. Simply provide your vehicle’s VIN during or after checkout, and it will arrive ready for a plug-and-play installation.
What information do you need from me?
We only need your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to flash the module with the exact software and calibrations your specific vehicle requires.
Is this part difficult to install?
For someone with basic mechanical skills, installation is typically straightforward. The PCM is usually located in the engine bay. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to swap in the new one. We always recommend consulting a repair manual for your specific model.
Will I need to perform a security relearn procedure?
Yes, on most GM vehicles of this era, you will need to perform a simple security relearn after installation. This procedure, often called the “Passlock Relearn,” typically involves cycling the ignition key and can be done in your driveway in about 30 minutes without any special tools.
Will this fix my check engine light?
If the check engine light and performance issues are being caused by a faulty PCM, then this part will resolve those issues. It is crucial to have your vehicle properly diagnosed to confirm the PCM is the point of failure before ordering.
How does the one-year warranty work?
This unit is backed by our one-year replacement warranty. In the unlikely event of a failure within one year of the purchase date, we will provide a replacement unit.
