Restore Your Envoy’s Reliability and Performance
Is your GMC Envoy suffering from frustrating and unpredictable issues like a persistent check engine light, rough idling, stalling, or poor fuel economy? These are classic signs of a failing Engine Control Module (ECM), the critical computer that manages your vehicle’s engine performance. Don’t let a faulty ECM keep you off the road. This pre-programmed engine computer is the definitive, hassle-free solution to restore your vehicle’s original performance and your peace of mind.
Common Symptoms & Your Solution
A failing ECM can cause a wide range of problems that can be difficult to diagnose. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Persistent Check Engine Light (CEL) with codes like P0601, P0606, or other communication errors.
- Unexplained drops in fuel efficiency.
- Engine stalling, stuttering, or misfiring.
- Difficulty starting the vehicle.
- Poor or hesitant acceleration.
- Erratic transmission shifting.
This module is the solution. We take the guesswork out of the repair by programming this exact 2007-2009 GMC Envoy Engine Control Module to your vehicle’s unique Vehicle Identification Number (VIN) before it ships. This ensures it works seamlessly with your specific configuration right out of the box.

Expert Insight: The Critical Role of VIN Programming
Think of the VIN as your vehicle’s DNA. Simply installing a used ECM from another vehicle without proper programming is like performing an organ transplant with the wrong blood type—it will be rejected. The security systems (like anti-theft) and specific component calibrations are all tied to the original VIN. Our professional programming service ensures that this new ‘brain’ is a perfect match for your vehicle’s body, preventing compatibility issues and ensuring all systems operate exactly as the manufacturer intended. This is the key difference between a quick fix and a correct, long-lasting repair for your 2007-2009 GMC Envoy Engine Control Module.
Frequently Asked Questions
What do I need to do after I purchase?
After you place your order, you must provide us with your vehicle’s 17-digit VIN. We cannot program or ship your module without it. You can typically add this in the order notes or send it to us via email with your order number.
Is this installation truly plug-and-play?
For most vehicles, yes. Because we pre-program the module, it is ready to be installed. However, in some GM vehicles, a security relearn procedure (also known as a CASE relearn or anti-theft relearn) may be required after installation. This is a simple procedure that can often be done without special tools and instructions can be readily found online for your specific model.
Will this fix my check engine light?
If the check engine light and associated diagnostic trouble codes (DTCs) are being caused by a faulty ECM, then this part will resolve the issue. It is crucial to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering a replacement 2007-2009 GMC Envoy Engine Control Module.
Where can I find my VIN?
Your Vehicle Identification Number (VIN) is located on a small plate on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Does this part fit vehicles other than the GMC Envoy?
Yes. This ECM is compatible with a very wide range of GM vehicles from makes like Chevrolet, Buick, Cadillac, Pontiac, Saturn, and more. Please review the detailed fitment list on this page to confirm it matches your specific year, make, and model.
