Restore Your Envoy’s Performance and Reliability
Is your GMC Envoy suffering from frustrating engine issues like stalling, poor fuel economy, intermittent starting, or a persistent Check Engine light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your engine’s performance. Don’t let a faulty computer keep you off the road. This professionally programmed Engine Control Module is the definitive solution to restore your SUV’s power, efficiency, and dependability.
Common Symptoms & Your Solution
A failing ECM can cause a wide range of confusing and difficult-to-diagnose problems. If you’re experiencing any of the following, a replacement module is often the answer:
- Unexplained Check Engine Light (with codes like P0601, P0606, or other internal processor faults)
- Engine stalling or shutting off while driving
- Severe hesitation or stumbling during acceleration
- Noticeable decrease in fuel mileage
- Transmission shifting erratically or harshly
- Complete no-start condition where the engine cranks but won’t fire

We take the guesswork out of the equation by pre-programming the unit to your vehicle’s specific Vehicle Identification Number (VIN), ensuring it works seamlessly with all your Envoy’s systems right out of the box.

An Expert’s Note on VIN Programming
“Why is VIN programming so critical? In modern vehicles like your Envoy, the ECM is the hub of a complex network. It doesn’t just manage the engine; it communicates with the transmission controller, the anti-theft system (PassLock/VATS), the instrument cluster, and more. Without programming specific to your VIN, these systems won’t recognize each other, leading to a no-start condition or a dashboard full of warning lights. Our process ensures this digital ‘handshake’ happens perfectly, making your installation as simple as changing a battery.”
Take control of your repair and get your vehicle running right. By providing us with your VIN at checkout, you ensure you receive a perfectly matched and updated programmed 2007-2009 GMC Envoy engine control module. It’s the smartest, most reliable way to solve complex electronic issues and get back to driving with confidence.
Frequently Asked Questions
Do I need to do any additional programming or flashing myself?
Absolutely not. This module is sold as a ‘plug-and-play’ solution. We handle all the programming to your specific VIN before it ships, so you can install it and start your vehicle without any extra steps.
Where is the ECM located on my 2007-2009 GMC Envoy?
On the GMC Envoy and its platform mates (like the Trailblazer and Saab 9-7x), the ECM is typically located on the driver’s side (LH) of the engine compartment, mounted to the engine itself or the inner fender.
How do I provide my VIN for programming?
After you complete your purchase, you can add your 17-digit VIN to the order notes or reply to your order confirmation email. We cannot ship your part until we have this information to ensure correct programming.
My original part number is different. Will this still work?
Yes, it will. GM uses many different service numbers for the same computer over its production life. As long as your vehicle’s year, make, and model are on the compatibility list, our VIN programming process ensures this module will function correctly as a replacement for any of the listed interchangeable service numbers.
Will this fix my Check Engine Light?
If the Check Engine Light is on due to an internal fault within the original ECM (like code P0601), then this replacement module will solve the problem. However, if the light is on for another reason (e.g., a bad oxygen sensor or a loose gas cap), you will still need to address that separate issue.
