Restore Peak Performance to Your GM Vehicle
Is your 2007 Saturn Aura, Chevy Malibu, or GMC Sierra running rough, stalling unexpectedly, or displaying a persistent Check Engine Light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine performance, fuel economy, and emissions. A faulty ECM can lead to a cascade of frustrating and potentially damaging issues. This replacement Engine Control Module, part number 19210738, is the definitive solution to restore your vehicle’s reliability and drivability.
Unlike generic modules that require expensive trips to the dealership for programming, this ECM arrives at your door fully programmed to your specific vehicle. We use your Vehicle Identification Number (VIN) to flash the module with the latest, most stable software updates directly from GM. This ensures perfect communication between the ECM and all other vehicle systems, providing a seamless, plug-and-play installation experience.
Common Symptoms of a Failing Engine Control Module
- ✔ Persistent and often inexplicable Check Engine Light (CEL).
- ✔ Engine stalling, sputtering, or misfiring, especially under load.
- ✔ Noticeable decrease in fuel economy.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass state emissions inspections.
- ✔ Communication errors with diagnostic scan tools.
From the Diagnostic Bay
We had a 2007 Chevy Impala come into the shop with an issue that had stumped two other mechanics. The car would run perfectly for about 15 minutes and then suddenly stall, refusing to restart for at least half an hour. There were no consistent trouble codes, just a history of random communication faults. After checking all the usual suspects—fuel pump, crank sensor, wiring harnesses—we focused on the ECM. We noticed that the module was getting excessively hot. On a hunch, we used a heat gun to gently warm the original ECM, and sure enough, the car stalled within minutes. We installed one of our VIN-programmed modules, and the problem was solved instantly. It’s a perfect example of how heat-related internal failure in an ECM can create ghost-like problems that are otherwise impossible to diagnose.

Installation and Setup
While professional installation is always recommended, swapping the ECM is often a straightforward process for the experienced DIY mechanic. The module is typically located in the engine bay, either on the firewall or near the battery. The key steps involve disconnecting the vehicle’s battery, carefully unplugging the wiring harnesses from the old module, unbolting it, and then installing the new one in the reverse order. Once the new, pre-programmed module is installed and the battery is reconnected, your vehicle is ready to go. In some cases, a security or crank relearn procedure may be necessary, which can be performed with many high-level scan tools.
Frequently Asked Questions
Do I need to do any additional programming after installation?
No. We program the module with the latest GM software using the VIN you provide. This makes it a plug-and-play installation. In some rare cases, a CASE (Crankshaft Angle Sensor Error) relearn may be needed, but no further flashing is required.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function.
Is this a new or used part?
This is a high-quality, tested, and guaranteed functional part sourced from a recycled vehicle. Each module is inspected and then programmed specifically for your vehicle.
What if my original part number is not on your list?
The part numbers listed (12589297, 12597121, 12603892, 19210738) are the most common compatible numbers. If your number is different, please contact us with your VIN. We can verify compatibility and ensure you receive the correct module for your vehicle.
Where is the ECM located on my 2007 Saturn Aura?
On the 2007 Saturn Aura, the Engine Control Module is typically located on the right-hand (passenger side) of the firewall in the engine compartment. Location can vary on other compatible models, so always verify before beginning work.
