Restore Your Envoy’s Performance and Reliability
Is your 2007, 2008, or 2009 GMC Envoy running rough, stalling unexpectedly, or displaying a stubborn check engine light? A failing Engine Control Module (ECM) is often the hidden culprit behind these frustrating and complex issues. This pre-programmed ECM is the definitive, hassle-free solution to restore your vehicle’s brain, getting you back on the road with confidence and peace of mind.
Common Symptoms & Your Direct Solution
A faulty ECM can cause a wide range of problems that are often misdiagnosed, leading to costly and unnecessary repairs. If you’re experiencing issues like poor acceleration, decreased fuel economy, erratic shifting, or a no-start condition, your engine computer may be to blame. Common diagnostic trouble codes (DTCs) like P0601, P0602, or P0606 often point directly to an internal module failure. Instead of chasing symptoms, this unit fixes the core problem. We take the guesswork out of the repair by programming this 2007-2009 GMC Envoy ECM specifically to your vehicle’s VIN before it ships.

Frequently Asked Questions
Do I need to do any additional programming myself?
No. We program the module to the VIN you provide before shipping. In most cases, it is a simple plug-and-play installation. Some vehicles may require a security relearn procedure, which is a simple process that can be done without any special tools.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the part until we receive this information, as the programming is essential for the part to function in your vehicle.
What is the difference between an ECM, ECU, and PCM?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the computer controlling engine functions. PCM (Powertrain Control Module) usually controls both the engine and the transmission. For your vehicle, this part serves as the primary brain for the powertrain.
Will this fix my specific problem?
This ECM will fix problems directly caused by a failing engine computer. While we cannot diagnose your vehicle remotely, symptoms like a no-start condition, communication error codes (like P0601), and erratic engine behavior are very common indicators of ECM failure.
Is this a brand new part?
This is a high-quality, tested, and guaranteed functional component that has been expertly prepared for your vehicle. Each unit is programmed with the latest software and verified to be in excellent working condition.
What happens if I have an issue after installation?
Your purchase is protected. This unit is backed by our one-year replacement warranty. If you encounter any issues with the module itself, please contact us, and we will be happy to assist you.
