Restore Peak Performance to Your 2.0L Turbocharged Engine
If you’re dealing with frustrating engine problems in your Pontiac Solstice, Saturn Sky, Chevy HHR, or Cobalt, a failing Engine Control Module (ECM) is often the culprit. I’ve spent countless hours in the shop diagnosing issues like erratic idling, stalling, no-start conditions, and a persistent Check Engine Light, and many times, the trail leads directly back to a faulty ECM. This isn’t just a replacement part; it’s a direct solution to get your vehicle running reliably again. This genuine GM ECM, part number 12623326, comes fully programmed to your vehicle’s specific VIN with the latest factory software updates. This critical step ensures all systems communicate correctly, restoring the precise fuel delivery, ignition timing, and transmission logic your car had when it left the factory.

Ordering a 2008-2010 Solstice ECM from us means you can bypass the expensive and time-consuming trip to a dealership for programming. We handle the complex part for you. Simply provide your VIN during checkout, and our technicians will flash the module with the correct, updated software for your exact vehicle. When it arrives, it’s ready for installation, saving you hundreds of dollars in dealer labor and programming fees. This is the most efficient way to solve your vehicle’s electronic brain teaser and get back to enjoying the drive.
From the Diagnostic Bay: The Case of the Confused Cobalt
A few months back, a 2009 Cobalt SS with the 2.0L turbo was towed into my bay. The owner was frustrated—the car would run fine for a week, then suddenly start misfiring, throwing random communication codes (U0100, U0101), and occasionally refusing to start. He had already replaced spark plugs and an ignition coil with no luck. After hooking up my scan tool and monitoring live data, I noticed the fuel trim and timing parameters were jumping all over the place without reason. This pointed to an internal processing error. We swapped in a pre-programmed ECM, and the car immediately ran like a top. The internal circuitry of the old module was failing intermittently, a classic symptom I’ve seen on these platforms. It’s a reminder that sometimes the most confusing problems have a straightforward electronic solution.
Common Signs of a Failing 2.0L ECM
- ✔ Check Engine Light is illuminated with codes like P0601 (Internal Control Module Memory Check Sum Error) or P0606 (ECM/PCM Processor Fault).
- ✔ Your vehicle experiences a no-start or hard-start condition.
- ✔ Unexplained drop in fuel economy.
- ✔ Engine stalling, stumbling, or running rough for no apparent reason.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Loss of communication with other modules, triggering various warning lights on the dash.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow the system to fully discharge.
- ✔ Locate the ECM: On the Solstice/Sky, it’s on the driver’s side front frame rail. For the Cobalt/HHR, check the driver’s side of the engine compartment (front for Cobalt, rear for HHR).
- ✔ Disconnect Connectors: Carefully release the locking tabs on the wiring harness connectors and pull them straight out from the module. Never force them.
- ✔ Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware as you will need it for the new unit.
- ✔ Install the New ECM: Mount your new, pre-programmed ECM and securely fasten it. Reconnect the wiring harnesses, ensuring they click firmly into place.
- ✔ Reconnect Battery: Re-attach the negative battery terminal. The vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Consult your owner’s manual for specific steps.

Frequently Asked Questions
Do I need to do anything after I install it?
Because we program the module to your VIN, it’s a much simpler process. However, some GM vehicles require a security relearn procedure (often called a Passlock or Passkey relearn) to sync the new ECM with your anti-theft system. This can usually be done without special tools.
What VIN do I provide?
Please provide the 17-digit Vehicle Identification Number (VIN) from the vehicle the ECM will be installed in. You can find it on your dashboard (visible through the windshield) or on your vehicle’s registration or insurance card.
Is this a brand new part?
This is a high-quality, tested, and verified genuine GM service part. We ensure every module meets strict performance standards before programming and shipping it to you.
Will this fix my Check Engine Light?
If the Check Engine Light is caused by an internal failure of your original ECM (like codes P0601-P0606), then this part is the correct fix. It’s essential to properly diagnose the issue first, as the light can be triggered by many other components like sensors or wiring.
How do I know if my ECM is the problem?
Common indicators include a no-start condition where the engine cranks but won’t fire, multiple unrelated trouble codes, and erratic engine behavior like stalling or surging that can’t be traced to mechanical parts. A professional diagnosis is the best way to be certain.
