Is Your Saturn Aura Running Rough? The PCM Might Be the Culprit.
The Powertrain Control Module, or PCM, is the central nervous system of your 2008-2009 Saturn Aura. It controls everything from fuel mixture and ignition timing to transmission shift points and emissions systems. When this critical component begins to fail, it can cause a cascade of confusing and frustrating problems, often leaving you stranded or dealing with poor performance. An illuminated Check Engine Light, erratic engine behavior, and decreased fuel economy are all classic signs that your vehicle’s brain is in trouble.
From the Diagnostic Bay
We had a 2009 Saturn Aura come into the shop with a persistent P0606 (PCM Processor Fault) code. The owner had already replaced the spark plugs and an oxygen sensor with no luck. The car would intermittently stall at red lights and had a noticeable hesitation during acceleration. After confirming all power and ground circuits to the module were solid, we knew the internal processor was failing. We installed one of our VIN-programmed PCMs, performed the quick security relearn, and the car ran perfectly. The owner was thrilled to have his reliable daily driver back without the dealership price tag.
Common Symptoms of a Failing PCM
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or misfiring
- ✔ Poor acceleration or loss of power
- ✔ Decreased fuel efficiency
- ✔ Harsh or erratic transmission shifting
- ✔ Vehicle failing to start or starting intermittently
- ✔ Communication errors with diagnostic scan tools

Frequently Asked Questions
Do I need to get this module programmed?
No. We handle the programming for you before shipment. You must provide us with your vehicle’s 17-digit VIN during or after checkout so we can load the correct software for your specific car. This makes the installation process much simpler.
What is a security relearn procedure?
Most GM vehicles have an anti-theft system (Pass-Key, Pass-Lock, or VTD) that requires the new PCM to be synchronized with your vehicle’s keys. This is a simple procedure that typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. We include instructions for this easy process.
Where is the PCM located on my 2008-2009 Saturn Aura?
On the 2008-2009 Saturn Aura, the Electronic Control Module (ECM/PCM) is typically located on the passenger side of the firewall in the engine compartment.
Will this fix my check engine light?
If the check engine light is caused by a faulty PCM, then yes, this part will resolve the issue. However, it’s crucial to properly diagnose the problem first. Other issues, such as a bad sensor or wiring problem, can also trigger a check engine light. This module will only fix codes related to the computer itself.
How do I find my vehicle’s VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard, visible through the windshield.
