Restore Your Pontiac G6’s Performance and Reliability
Is your Pontiac G6 suffering from frustrating issues like a persistent Check Engine Light, rough idling, stalling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM). Don’t let a faulty computer keep you off the road or lead to expensive, unnecessary repairs. This genuine OEM Engine Control Module is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN for a seamless, hassle-free installation.
Common Symptoms of a Failing G6 ECM & Your Solution
A vehicle’s ECM is its brain, controlling everything from fuel mixture and ignition timing to transmission shifting. When it fails, the symptoms can be confusing and widespread. This part is the direct fix for:
- Perpetual Check Engine Light (CEL)
- Error codes such as U0100 (Lost Communication with ECM)
- Engine stalling or cutting out unexpectedly
- Rough running, hesitation, or misfires
- Poor fuel economy
- Harsh or incorrect transmission shifting
- Failure to start, even with a good battery and starter

Expert Insight from a 20-Year Technician
I’ve seen countless drivers chase phantom issues, replacing perfectly good sensors and spark plugs, only to find the ECM was the root cause. A failing ECM can send out false signals, making diagnosis a nightmare. That’s why a pre-flashed unit is such a game-changer. We had a 2008 G6 in the shop that wouldn’t communicate with our scan tool. Instead of hours of wiring diagnostics, the owner opted for our Programmed Pontiac G6 ECM. Within 15 minutes of installation, the car started, the scan tool connected, and all systems were go. The VIN programming is the critical step that ensures all the vehicle’s modules can talk to each other properly—it’s the key to a successful repair.
Take the guesswork out of your repair. With our Programmed Pontiac G6 ECM, you get a reliable, updated, and ready-to-install brain for your vehicle. Simply provide your VIN during checkout, and we’ll handle the rest, getting you back on the road with confidence.
Frequently Asked Questions
Do I need to do any programming after I receive this part?
No. This ECM comes fully programmed to your vehicle’s specific VIN. It is a plug-and-play installation. In some cases, a security relearn procedure may be required, which is a simple process that can be done without any special tools.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on the driver’s side of the dashboard, visible through the windshield.
How do I know for sure that my ECM is the problem?
While the symptoms listed are strong indicators, it’s always best to have the vehicle properly diagnosed. Common signs include communication error codes (like U0100), multiple unrelated error codes appearing at once, or if all other potential causes (sensors, wiring) have been ruled out.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function in your vehicle. After your purchase, we will contact you to request the VIN if it was not provided.
Is this compatible with other vehicles besides the 2006-2009 Pontiac G6?
Yes. This ECM, service number 12590032 and its interchanges, fits a very wide variety of GM vehicles from Buick, Cadillac, Chevrolet, GMC, and more. Please carefully review the detailed fitment list on this page to confirm compatibility with your specific model and engine.
