Is Your Saturn VUE Running Rough or Not Starting?
The Engine Control Module (ECM), often called the engine computer, is the central command center of your 2008-2010 Saturn VUE. It meticulously manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When this critical component begins to fail, it can cause a cascade of frustrating and seemingly unrelated issues, leaving you stranded and facing a confusing diagnosis. If you’re dealing with an intermittent no-start condition, poor fuel economy, or a persistent Check Engine Light, a faulty ECM is a likely culprit.
From the Diagnostic Bay
We had a 2009 Saturn VUE with the 3.6L engine come into the shop with a complaint of intermittent stalling at stoplights and a general lack of power. The owner had already replaced the spark plugs and a coil pack with no improvement. Our initial scan showed a handful of communication error codes with other modules, which is a classic red flag for an ECM issue. After verifying power and ground to the module were solid, we connected a scope and saw a noisy 5-volt reference signal. We swapped in a pre-programmed ECM, and the VUE ran perfectly. The owner was thrilled to have his reliable daily driver back without wasting more money on unnecessary parts.
Symptoms of a Failing Engine Control Module

- ✔ Complete no-start or hard-starting conditions
- ✔ Noticeable decrease in fuel efficiency
- ✔ Poor engine performance, including rough idling and lack of acceleration

Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This is the primary benefit of our service. We program the Engine Control Module to your vehicle’s specific VIN before we ship it. It will arrive ready for installation with no additional programming 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. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your insurance and registration documents.
Where is the ECM located on a 2008-2010 Saturn VUE?
The location can vary slightly based on the engine. For the 2.4L engine, it’s typically on the right-hand (passenger side) firewall. For the 3.6L engine, it is often found in the engine compartment as well. Always consult a repair manual for your specific model to confirm the exact location before beginning work.

This module is a direct replacement for several GM service numbers. Please check the list of interchangeable numbers provided in our description (12590032, 12602044, 12605843, etc.). If your number is on that list, this part is a correct replacement for your vehicle.
Will this fix my Check Engine Light?
If the Check Engine Light and associated codes are caused by a faulty ECM, then yes, this part will resolve the issue. It is always recommended to have a proper diagnosis performed by a qualified technician to confirm the ECM is the root cause of the problem before ordering.
