Is Your Solstice Running Rough? The Engine’s Brain Might Be the Problem.
If your 2006 Pontiac Solstice is experiencing frustrating issues like stalling, poor fuel economy, a persistent check engine light, or erratic engine behavior, the cause is often a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it starts to fail, it can cause a cascade of problems that are difficult to diagnose and can sideline your car indefinitely.
Don’t let a faulty computer ruin your driving experience. This Engine Control Module, part number 19210737, is the definitive solution to restore your vehicle’s performance and reliability. We take the guesswork and hassle out of the repair by programming the module specifically for your vehicle using your VIN. This means it arrives at your door with the latest GM factory software updates already installed, ready for a straightforward installation.
From the Diagnostic Bay
We had a 2006 Solstice come in with a really bizarre issue. The owner complained of intermittent stalling at stoplights and a cooling fan that would run constantly, even when the engine was cold. We checked all the sensors and wiring, and everything seemed fine. No clear codes were pointing to a specific component. On a hunch, we monitored the data stream from the ECM and noticed the coolant temperature reading was jumping all over the place, even though the sensor was new. The original ECM had an internal fault causing it to misinterpret sensor data. Swapping in a VIN-programmed module like this one solved every single issue instantly. It’s a reminder that the ECM is the true heart of the car’s electronics.
Symptoms of a Failing 2006 Solstice ECM
- ✔ Check Engine Light is on with various, often confusing, trouble codes.
- ✔ Engine stalling, sputtering, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Rough or unstable idling.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Communication errors with diagnostic scan tools.
