Is Your Chevy Spark Running Rough?
If your 2014 or 2015 Chevrolet Spark is experiencing frustrating issues like stalling, erratic idling, a persistent check engine light, or a complete no-start condition, a failing Engine Control Module (ECM) is a likely culprit. The ECM is the brain of your vehicle’s engine, managing everything from fuel injection and ignition timing to emissions control. When it fails, it can cause a cascade of problems that leave you stranded and facing a complex repair. Don’t let a faulty computer dictate your car’s reliability. This direct-replacement ECM, part number 12692200, is the definitive solution to restore your Spark’s performance and peace of mind.
From the Diagnostic Bay
We had a 2015 Chevy Sonic (which uses a similar ECM) come into the shop with a bizarre issue. The customer complained of random stalling, but only after the car was fully warmed up. We checked everything—fuel pressure, spark, sensors—and all tested fine. No codes were stored, which was the most frustrating part. On a hunch, we monitored the live data stream from the ECM and noticed that the injector pulse width would suddenly drop to zero right before it stalled. After swapping in a known-good, programmed ECM, the problem vanished. It was a classic case of internal ECM failure under thermal stress, a problem that’s impossible to diagnose with a simple code reader and highlights the importance of replacing the entire unit when it begins to fail intermittently.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is on with various, often unrelated, trouble codes.
- ✔ Engine stalls unexpectedly or refuses to start at all.
- ✔ Noticeable decrease in fuel economy and engine performance.
- ✔ Rough or inconsistent idling and hesitation during acceleration.
- ✔ Automatic transmission shifting issues or harsh engagement.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Misfire codes even after replacing spark plugs and coils.
The Plug-and-Play Solution: A Programmed 2014-2015 Spark ECM
The biggest hurdle in replacing a modern ECM is the complex programming required to make it communicate with your specific vehicle. This isn’t a part you can simply pull from a junkyard and install. Our process eliminates this challenge. When you purchase this module, we require your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians will then flash the ECM with the latest, most stable software updates directly from GM. This ensures the computer is perfectly matched to your Spark’s factory settings, options, and security system. The result is a true plug-and-play installation. In most cases, no further dealer visits or expensive programming tools are needed.
Guaranteed Compatibility
This module is a direct replacement for a wide range of GM vehicles and part numbers, ensuring a perfect fit and function. It is compatible with part numbers: 12668866, 12668994, 12643636, 12663405, 12670335, 22819494, and 12692200. While it fits many models like the Cruze, Sonic, and Trax, this listing is specifically for the 2014-2015 Spark ECM, and the programming will be tailored precisely for that application. By providing your VIN, you guarantee that the software loaded onto the module is the correct one for your car, restoring its original factory performance and efficiency.
Frequently Asked Questions
What do I need to do after I purchase?
After you place your order, you must send us your vehicle’s 17-digit VIN. We cannot ship the module until we have this information, as the programming is specific to your car.
Is this ECM difficult to install?
The physical installation is straightforward for a DIY mechanic. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. Because we pre-program it, you avoid the complex software setup. However, some GM vehicles may require a simple security relearn procedure, which can be done without special tools and instructions can be found online.
Will this fix my check engine light?
If the check engine light and other symptoms are caused by a faulty ECM, this part will resolve those issues. It’s crucial to ensure you have properly diagnosed the problem and ruled out other components like sensors or wiring.
What if I have a different part number?
This module replaces several part numbers, including 12668866, 12668994, 12643636, and more as listed in the description. As long as your vehicle is a 2014-2015 Spark, this is the correct part, and our VIN programming ensures it works perfectly.
Is there a warranty?
Yes, all our modules come with a standard warranty against defects. Please refer to the warranty information section on our website for complete details and duration.
