Is Your Vehicle Running Poorly or Not Starting?
If your Chevrolet Cobalt, Pontiac G6, or another compatible GM vehicle is experiencing frustrating issues like stalling, erratic performance, poor fuel economy, or a persistent check engine light, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions systems. When it fails, the symptoms can be widespread and difficult to diagnose. This VIN-programmed ECM, part number 12630457, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We recently worked on a 2006 Pontiac G6 that had its owner completely stumped. The car would randomly stall at intersections and had a check engine light that multiple shops couldn’t solve by just replacing sensors. After confirming the wiring and sensors were good, we pinpointed the ECM. The internal logic was failing intermittently. Instead of a costly trip to the dealer for a new unit and programming, the owner ordered this exact part. We installed it, performed a quick security relearn, and the car ran flawlessly. It’s a common story, and this pre-programmed module is the most efficient fix.
Restore Peak Performance with a 2006 Cobalt Engine Module
Don’t let a faulty computer keep you off the road. This module isn’t just a replacement part; it’s a complete solution. We take the guesswork out of the repair by pre-programming the unit with the latest official GM software specifically for your vehicle’s Vehicle Identification Number (VIN). This ensures that all parameters are set to factory specifications, providing optimal engine performance, fuel efficiency, and emissions control the moment it’s installed. It’s a true plug-and-play solution that saves you a trip to the dealership and expensive programming fees.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL)
- ✔ Engine stalling or misfiring for no apparent reason
- ✔ Difficulty starting or a no-start condition
- ✔ Noticeable decrease in fuel economy
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Loss of power and poor acceleration
- ✔ Communication errors with diagnostic scan tools
This unit is a direct replacement for a wide range of GM vehicles and is interchangeable with multiple service numbers, including 12590032, 12602044, 12603530, and more. By providing your VIN during checkout, you guarantee that the 2006 Cobalt Engine Module you receive is perfectly matched to your vehicle’s specific configuration, options, and emissions standards. The installation is straightforward for any competent mechanic or experienced DIYer, getting your car back to factory-fresh operation quickly and affordably.
Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your VIN allows us to load the exact, vehicle-specific software and calibrations from GM. This ensures perfect compatibility with your engine, transmission, and other systems, making the unit ready for installation right out of the box.
Is this module difficult to install?
For most vehicles, the ECM is in an accessible location (like the air cleaner housing or firewall) and can be swapped with basic hand tools. However, we always recommend installation by a qualified technician to ensure it’s done correctly. After installation, a simple security relearn procedure may be required, which can often be done without special tools.
Will this fix my check engine light?
If the check engine light and other symptoms are caused by a faulty ECM, this replacement part will resolve the issue. It’s crucial to ensure that other potential problems (like faulty sensors or wiring) have been ruled out first.
What does ‘interchangeable service number’ mean?
GM often uses several different part numbers for the same physical component over its production life. Our module is a direct replacement for all the listed service numbers (e.g., 12590032, 12607096, 19210737), guaranteeing a perfect fit and function.
Is any additional programming required after installation?
No. We handle all the necessary programming before shipping. The unit arrives ready to be installed. The only potential step is a security or anti-theft relearn, which pairs the new ECM to your vehicle’s keys. This procedure is typically straightforward and instructions can be easily found online for your specific model.
