Restore Peak Performance to Your Saturn Aura
Is your 2008 or 2009 Saturn Aura running rough, stalling unexpectedly, or displaying a persistent check engine light? These are common indicators of a failing Engine Control Module (ECM), the central computer responsible for managing 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 ECM, part number 12629019, is the definitive solution to get your vehicle back on the road and running like new.
Expert Pro Tip
Before replacing your ECM, always perform a full battery and charging system test. A weak battery or faulty alternator can cause low voltage conditions that mimic ECM failure. Also, inspect the main engine ground straps for corrosion or looseness. A poor ground connection is a common and often overlooked cause of erratic electronic behavior.
Symptoms of a Failing 2008-2009 Aura ECM
- âś” Check Engine Light: The most common symptom, often with codes related to sensors, communication errors (U-codes), or processor faults.
- âś” Engine Stalling or Misfiring: The engine may stall intermittently, misfire, or run very poorly as the ECM fails to properly control spark and fuel.
- âś” No-Start Condition: A completely failed ECM can prevent the engine from starting at all by not activating the fuel pump or ignition coils.
- âś” Poor Fuel Economy: Inefficient engine operation due to incorrect fuel and air calculations from a failing module will noticeably decrease your MPG.
- âś” Transmission Shifting Problems: The ECM works with the Transmission Control Module (TCM). A faulty ECM can send incorrect data, leading to harsh shifting or getting stuck in gear.
- âś” Inconsistent Performance: You might experience hesitation during acceleration, rough idling, or a general lack of power.

Frequently Asked Questions
Do I need to do anything after installing this ECM?
Yes. While we program the module to your VIN, you will need to perform a security relearn procedure (also known as a key relearn or anti-theft relearn). This process syncs the new ECM with your vehicle’s existing keys and security system. It typically involves a series of key cycles and can be done without special tools. We include instructions to guide you through this simple process.
How do I provide my VIN?
After completing your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module until we receive this information. Please ensure the VIN is accurate to avoid any compatibility issues.
Is this a guaranteed fix for my vehicle’s problems?
This ECM will fix issues directly caused by a faulty engine computer. However, it’s crucial to have your vehicle properly diagnosed. Problems like a bad sensor, wiring issue, or a failing fuel pump can present similar symptoms. This part is the solution for a confirmed bad 2008-2009 Aura ECM.
Will this ECM have the latest software?
Yes. We flash each module with the latest GM-certified software updates available for your specific VIN. This ensures your vehicle benefits from any improvements in performance, emissions, and drivability that the manufacturer has released since your car was new.
Where is the ECM located on a 2008-2009 Saturn Aura?
On the 2008-2009 Saturn Aura, the Engine Control Module is typically located on the passenger side of the firewall in the engine compartment. Always disconnect the battery before attempting to remove or install the module.
