Is Your 2.0L Turbo Engine Acting Up? It Could Be The ECM.
If you’re driving a 2008-2010 Pontiac Solstice, Saturn Sky, Chevy HHR, or Cobalt with the powerful 2.0L turbocharged engine, you know how exhilarating it can be. But when performance starts to suffer, it can be incredibly frustrating. Unexplained stalling, rough idling, a persistent Check Engine Light, or a complete no-start condition can often point to a single, critical component: the Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, and when it fails, it can cause a cascade of confusing and debilitating issues.
This listing is for a direct replacement Engine Control Module, part number 12623326 (interchangeable with 12614967). We take the guesswork and hassle out of the repair process. Instead of buying a used module and paying hundreds at a dealership for programming, we handle it all for you. Simply provide us with your vehicle’s VIN during checkout, and we will program the module with the latest GM-certified software specific to your car. It arrives at your door ready for a straightforward installation, getting you back on the road quickly and affordably.
From the Diagnostic Bay
We had a 2009 Solstice GXP come into the shop on a tow truck. The owner was convinced the fuel pump had failed because the car would crank but never start. He had already replaced it himself, with no luck. We scanned the vehicle and found a host of communication error codes, all pointing back to the ECM. There was no ‘Check Engine’ light, which threw him off. After confirming power and ground to the module were good, we connected a test ECM, and the engine fired right up. It’s a classic case where the symptoms don’t always tell the whole story. A faulty ECM can mimic many other component failures, making proper diagnosis key.
Diagnosing a Faulty 2008-2010 Solstice ECM
A failing engine computer can manifest in various ways, often intermittently at first. If you’re experiencing any of the issues below, a faulty ECM is a likely culprit. Ignoring these signs can lead to further component damage, poor fuel economy, and unpredictable vehicle behavior.
Common Symptoms of ECM Failure
- ✔ Check Engine Light: The light is on, and you may have codes related to module communication (U-codes) or multiple, unrelated sensor failures.
- ✔ No-Start Condition: The engine cranks over but will not start, often due to a lack of spark or fuel injector pulse commanded by the ECM.
- ✔ Poor Engine Performance: You may notice a significant loss of power, hesitation during acceleration, or random misfires.
- ✔ Erratic Shifting or Transmission Issues: The ECM works with the Transmission Control Module (TCM), and a fault can cause shifting problems in automatic models.
- ✔ Stalling for No Reason: The engine may stall unexpectedly while driving or when coming to a stop.
- ✔ Reduced Fuel Economy: A failing ECM can’t properly manage the air-fuel mixture, leading to a noticeable drop in MPG.
- ✔ Cooling Fans Not Working: The ECM often controls the engine’s cooling fans, and a failure can cause the engine to overheat.

Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No. We program the module to the VIN you provide before it ships. It will arrive ready to install and start the vehicle.
Where is the ECM located on my vehicle?
The location varies slightly by model. On the Solstice and Sky, it’s on the LH front frame rail. On the HHR, it’s in the LH rear of the engine compartment. On the Cobalt, it’s in the LH front of the engine compartment. Always disconnect the battery before removal or installation.
Is this part number 12623326 compatible with 12614967?
Yes, these two part numbers are interchangeable. This module is a direct replacement for either service number.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This is critical for us to load the correct software for your specific car.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty ECM, this replacement part will solve the issue. However, if there are other mechanical or electrical problems with the vehicle, this will not fix them. Proper diagnosis is always recommended.
