Restore Your Saturn’s Performance and Reliability
Is your 2007 Saturn Aura suffering from frustrating and unpredictable issues like stalling, poor acceleration, or a persistent check engine light?

A Technician’s Perspective: As a mechanic with over 20 years on the floor, I’ve seen the chaos a ‘one-size-fits-all’ module can cause. They often create new, more confusing problems. That’s why programming to the VIN is non-negotiable. It ensures the ECM knows everything about your specific vehicleโfrom the transmission type to the emissions equipment. Ordering a pre-programmed 2007 Saturn Aura programmed ECM 12597121 is the single best way to ensure a successful, long-lasting repair.

Frequently Asked Questions
Do I need to take this to a dealer for programming?
Absolutely not. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. It arrives ready to be installed, saving you time and the high cost of dealership programming services.
What information do you need from me?
After you place your order, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot program or ship your ECM without it. The VIN is typically found on your driver’s side dashboard (visible through the windshield) or on the driver’s door jamb sticker.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM (common diagnostic codes include P0601, P0606), then this part will solve the problem. However, it’s crucial to ensure a proper diagnosis has been performed, as other sensors or wiring issues can also trigger a check engine light.
Is this a difficult part to install myself?
For someone with basic mechanical skills and tools, replacing an ECM is generally straightforward. On the 2007 Saturn Aura, it is located on the right-hand (passenger side) firewall. While the physical swap is simple, some vehicles may require a security relearn procedure (often called a ‘key relearn’) to sync the new ECM with your keys. This procedure is simple and can be done without special tools.
Is this compatible with other vehicles?
Yes, this specific ECM, the E38 controller, was used across a wide range of 2007 GM vehicles, including trucks, SUVs, and other sedans. While this listing is focused on the 2007 Saturn Aura programmed ECM 12597121, the part itself fits many models. Our VIN programming ensures it works perfectly for your specific application.
