Is Your 2006 Solstice Running Rough, Stalling, or Refusing to Start?
The Pontiac Solstice is a fantastic driver’s car, but when the Engine Control Module (ECM) starts to fail, that driving joy quickly turns into a major headache. As the ‘brain’ of your vehicle’s engine, the ECM is responsible for everything from fuel mixture and ignition timing to transmission shifting and emissions control. When it goes bad, the symptoms can be unpredictable and frustrating.
From the Shop Floor: A Real-World Diagnostic
“A customer’s 2006 Solstice came in last week with these exact symptoms. It would start and run fine for 20 minutes, then suddenly die and refuse to restart for an hour. Other times, it wouldn’t start at all. The check engine light was on, and a scan revealed code P0606 – ECM Processor Fault. After verifying the power and ground circuits to the module were solid, we knew the internal processor was failing. This is a common failure I’ve seen hundreds of times, often caused by years of heat cycles and vibration, especially given the ECM’s location on the Solstice’s front frame rail.”
The Critical Symptoms of a Failing Solstice ECM
If you’re experiencing any of the following issues, a faulty ECM is a very likely culprit. I’ve diagnosed these problems countless times in my 20+ years as a technician:
- โ Check Engine Light is illuminated with communication or processor-related codes (like P0601, P0606).
- โ The engine cranks but refuses to start, or starts and immediately stalls.
- โ Unexplained drops in fuel economy and poor engine performance.
- โ Harsh or erratic automatic transmission shifting.
- โ The cooling fans run constantly, even when the engine is cold.
- โ Complete no-start, no-communication condition where a scan tool cannot connect to the ECM.
The Plug-and-Play Solution: Programmed and Ready for Installation
Replacing an ECM isn’t just about swapping the hardware. The module must be programmed with your car’s specific Vehicle Identification Number (VIN). Without this step, the car won’t start due to the anti-theft system, and it won’t have the correct software for your engine, transmission, and options. This traditionally means an expensive trip to the dealership for programming after you’ve already installed the part.
We eliminate that entire hassle. When you purchase this ECM, we use your VIN to flash the module with the latest, most stable software directly from GM. This ensures all known bugs and performance issues from the original 2006 calibration are corrected. It arrives at your door ready for installation.
Guaranteed Fitment and Compatibility
This ECM, part number 19210737, is a direct replacement for a wide range of GM vehicles. To ensure perfect compatibility, please verify that your original module carries one of the following service numbers:
- โ 12590032
- โ 12602044
- โ 12603530
- โ 12605843
- โ 12607096
- โ 12630457
- โ 19210737
For the 2006 Pontiac Solstice, the ECM is located on the left-hand (driver’s side) front frame rail. Installation is straightforward, but remember to disconnect the battery before beginning. After installation, you may need to perform a simple security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. This allows the new ECM to sync with your vehicle’s other security modules.
