Get Your Performance Car Back on the Road, Fast.
There’s nothing more frustrating than when your spirited Solstice, Sky, Cobalt SS, or HHR SS starts acting up. Hesitation, stalling, or a persistent Check Engine Light can rob you of the driving joy these cars were built to deliver. You need a reliable solution that doesn’t involve expensive diagnostic guesswork or a trip to the dealership. This Engine Control Module (ECM) is the definitive answer, arriving at your door fully programmed to your vehicle’s specific VIN, ready to restore the performance and reliability you expect.
Common Symptoms of a Failing ECM & Your Direct-Fit Solution
A failing engine computer can manifest in numerous ways, often mimicking other sensor failures. If you’re experiencing any of the following, a faulty ECM is a likely culprit:
- Check Engine Light (CEL) with communication-related codes (like P0601, P0606) or multiple random sensor codes.
- Engine Stalling or Misfiring for no apparent reason, especially after warming up.
- No-Start Condition where the engine cranks but refuses to fire.
- Noticeable Drop in Fuel Economy or poor engine performance.
- Erratic automatic transmission shifting or other electronic module issues.
This pre-programmed GM 2.0L Turbo ECM 12623326 is the solution. We take a quality OEM unit and flash it with the latest, most stable software updates from General Motors, tailored specifically to your vehicle using the VIN you provide. This ensures that all parameters for fuel injection, ignition timing, turbocharger control, and emissions are set perfectly for your car, right out of the box.

An Expert’s Note on VIN Programming
As a technician, I’ve seen countless issues arise from using incorrect or non-programmed modules, especially on these sophisticated 2.0L direct-injected turbo engines. The ECM controls everything from the high-pressure fuel pump to the turbo wastegate. Simply installing a used computer from another car won’t work—the vehicle’s security system will prevent it from starting. Our VIN-flashing service pre-loads all the critical, vehicle-specific data, including the security key information, so the new ECM is immediately accepted by your car’s network. This is the only way to ensure a proper, lasting repair.
Don’t let a faulty computer keep your performance car parked. This is your opportunity to solve the problem correctly the first time. By providing your VIN upon purchase, you ensure you receive a computer that is 100% ready for installation. Get your car back to running at its absolute best with this reliable GM 2.0L Turbo ECM 12623326.
Frequently Asked Questions
Do I need to do anything after installation?
In most cases, this is a direct plug-in installation. However, some GM vehicles may require a simple, key-on/key-off security relearn procedure that takes about 30 minutes and requires no special tools. We include instructions for this common procedure. A crankshaft position sensor variation relearn (CASE relearn) may also be needed with a capable scan tool to turn off the Check Engine Light, though the vehicle will run and drive without it.
Where is this ECM located on my vehicle?
The location varies slightly by model. On the Solstice and Sky, it’s on the LH (driver’s side) front frame rail. On the Cobalt, it’s in the LH front of the engine compartment. For the HHR, it’s located in the LH rear of the engine compartment. Always disconnect the battery before removal and installation.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive an order confirmation email. Simply reply to that email with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive your VIN, as programming is a required step.
Is this a brand new part?
This is a professionally prepared OEM part that has been thoroughly inspected, tested, and loaded with fresh, vehicle-specific software. It is guaranteed to function to original equipment standards.
What if my vehicle has modifications?
Our programming service uses factory GM software for stock vehicles. This ECM is not intended for vehicles with significant hardware modifications like larger turbos, different injectors, or aftermarket camshafts, as it does not contain a special performance calibration.
