Restore Your Envoy’s Performance and Reliability
Is your 2006 GMC Envoy giving you headaches? Unpredictable stalling, a persistent check engine light, or rough running can point directly to a failing Powertrain Control Module (PCM). This isn’t just an inconvenience; it’s a critical issue that affects your vehicle’s safety, fuel economy, and overall drivability. Stop guessing and replace the core of your engine’s management system with a solution designed for a perfect fit and function.
Common Symptoms of a Failing PCM & Your Solution
If you’re experiencing any of the following, a faulty engine computer is the likely culprit:
- Check Engine Light: Especially with diagnostic trouble codes (DTCs) like P0601, P0602, P0606, or other internal processor errors.
- Engine Stalling or No-Start: The engine may crank but refuse to start, or it might stall intermittently while driving.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel efficiency.
- Erratic Shifting: The transmission may shift harshly, late, or not at all, as the PCM also controls transmission functions.
- Communication Errors: Your mechanic’s scan tool may be unable to communicate with the PCM.
This Powertrain Control Module is the definitive solution. We take the guesswork out of the repair by pre-programming it specifically for your vehicle using your VIN. This ensures that it has the correct calibration and the latest software updates from GM, making the installation process as simple as possible. This is the quality repair your vehicle deserves, designed to get you back on the road with confidence.

An Expert’s Note: From over 20 years in the shop, I’ve seen countless vehicles with mysterious issues that all traced back to the PCM. Simply swapping a used computer from a junkyard won’t work on these modern vehicles due to anti-theft systems and specific vehicle calibrations. Our process of programming this 2006 GMC Envoy PCM to your exact VIN is what makes it a true, reliable fix. We ensure the module we send you is not just a replacement, but the correct one for your specific vehicle, loaded with the latest GM software for peak operation.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This module comes fully programmed to the VIN you provide. The only step you may need to perform is a simple security relearn procedure, which can be done without any special tools. We provide easy-to-follow instructions for this process.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential.
Is this the right part for my vehicle?
This 2006 GMC Envoy PCM is compatible with a wide range of GM trucks and SUVs from 2004-2006. Please review the detailed fitment list and cross-reference the part numbers in the description to ensure it matches your specific application. If you are unsure, please contact us with your VIN before ordering.
What is the security relearn procedure?
For most GM vehicles of this era, it’s a simple key-on/key-off sequence. Typically, you turn the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeat this cycle three times. This allows your vehicle’s anti-theft system to recognize the new PCM.
Will this fix my check engine light?
This module will resolve any check engine light and performance issues directly caused by a failing PCM. However, if the light is on due to other problems (like a bad oxygen sensor or catalytic converter), those issues will still need to be addressed separately.
