Restore Your Chevrolet’s Performance and Reliability
If you’re dealing with a frustrating check engine light, poor fuel economy, stalling, or a no-start condition in your 2016 Chevrolet Spark, a failing Engine Control Module (ECM) is often the culprit. As the brain of your vehicle’s engine, a faulty ECM can cause a cascade of confusing and costly problems. I’ve seen it countless times in the shop: a car comes in running rough, and after hours of chasing sensors, the root cause is the main computer. This isn’t just an inconvenience; it’s a critical component for your car’s safety and efficiency.
This listing is for a direct-fit replacement ECM, compatible with part numbers 12672780 and 12660743. We take the guesswork and high dealership costs out of the equation. Before we ship, we will flash the module with the very latest GM-certified software, specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN). This ensures seamless communication with your car’s other systems and restores its original performance specifications. You get a reliable part that’s ready for installation right out of the box, saving you a trip to the dealer and hundreds of dollars in programming fees.
Case Study: A Tricky Diagnosis
A customer brought in a 2016 Spark with an intermittent stalling issue that no other shop could solve. The car would run fine for days, then suddenly die at a stoplight. There were no consistent trouble codes, making it a diagnostic nightmare. After checking the fuel pressure and ignition system, I focused on the 2016 Spark ECM. I noticed on the live data stream that the short-term fuel trim would erratically spike just before a stall. Based on experience, I knew this pointed to a processing fault within the module itself. We replaced it with one of our VIN-programmed units, and the problem was solved instantly. The customer was thrilled to have their reliable daily driver back.

A Straightforward Guide to Installation
Installing your new ECM is a manageable job for a confident DIYer. Following these steps will help ensure a smooth process. Always consult a service manual for your specific vehicle’s torque specs and procedures.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow all systems to power down completely.
- Locate the ECM: On the 2016 Spark, the ECM is typically located in the engine bay, often near the battery or firewall. It’s a metal box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. There are usually locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed ECM onto the bracket and securely tighten the bolts. Reconnect the electrical connectors, ensuring they click firmly into place.
- Final Steps: Reconnect 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. Start the engine and let it idle to confirm proper operation.
