As a technician, I’ve seen countless mid-2000s GM vehicles plagued by ECM issues. These modules, often located in harsh engine bay environments, are prone to failure over time from heat and vibration. Many people try a used part from a salvage yard, only to find out it still needs to be programmed by a dealer—a costly and inconvenient extra step. Our solution bypasses that headache completely. By providing us with your VIN, you receive a dependable 2007 Impala Engine Control Module 19210738 that has been professionally programmed and is ready for a simple installation, getting you back to a reliable daily driver without the extra hassle.
Frequently Asked Questions
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN, or add it to the ‘notes’ section during checkout. We cannot ship your part until we receive this information.
Will I need to do anything else after installing this ECM?
In most cases, you will need to perform a simple security relearn procedure (also known as a CASE relearn or anti-theft relearn). This procedure can typically be done without any special tools and involves a sequence of key turns. Instructions are widely available online for your specific model.
Is this a brand new part?
This is a high-quality, inspected, and tested replacement part that is guaranteed to perform to OEM standards. Each unit is verified before being programmed and shipped.
Will this module fit vehicles other than a 2007 Impala?
Yes. This ECM is compatible with a wide array of 2006-2008 GM cars, trucks, and SUVs. Please see the detailed fitment list on this page to confirm it is the correct part for your specific vehicle and engine option. The 2007 Impala Engine Control Module 19210738 is one of the most common applications.
Will this fix my car’s problem for sure?
If your vehicle’s issues have been correctly diagnosed as a faulty ECM, this part will resolve them. However, it will not fix problems caused by other failed components like sensors, wiring, or mechanical parts. We always recommend a proper diagnosis by a qualified technician.
