Are you battling a persistent check engine light, experiencing sudden stalling, rough idling, or a noticeable drop in fuel economy in your vehicle?

Frequently Asked Questions
What is VIN programming and why do I need it?
VIN programming is the process of loading your car’s specific software and security information onto the ECM. This is crucial for it to communicate correctly with your engine, transmission, anti-theft system, and other modules. Our service handles this for you, so the part is ready to install upon arrival.
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 your part until we receive this information, as it is essential for the programming process.
Is this part difficult to install?
For someone with moderate mechanical skill, replacing an ECM is typically straightforward. It usually involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module to swap in the new one. However, we always recommend consulting a repair manual for your specific vehicle or seeking help from a qualified mechanic if you are unsure.
Will this fix my check engine light?
If the check engine light is on due to an internal fault in your old ECM (like error code P0601), this replacement module is the correct fix. After installation, you will need to clear the codes with a standard OBD2 scanner to turn off the light.
Does this fit vehicles other than the 2008-2009 Impala?
Yes. This 2008-2009 Impala Engine Control Module is a genuine GM part that is interchangeable with numerous service numbers and fits a very wide range of GM cars, trucks, and SUVs. Please review the detailed fitment list on this page to confirm compatibility with your specific make, model, and engine.
What 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 our support team will be ready to assist you.
