Restore Your Chevrolet Spark’s Performance and Reliability
Is your 2016 Chevy Spark suffering from frustrating and unpredictable issues like stalling, a persistent check engine light, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine performance, fuel economy, and emissions. Don’t let a faulty module keep you off the road. This direct-fit replacement ECM, compatible with part numbers 12660743 and 12672780, is the definitive solution to get your car running smoothly again.
The biggest challenge with replacing a modern ECM is the need for expensive dealership programming. We eliminate that step entirely. Before this module ships, we will flash it with the latest official GM software, perfectly matched to your car’s unique Vehicle Identification Number (VIN). This means it arrives at your door ready for a straightforward installation, saving you hundreds of dollars and significant downtime. This isn’t just a part; it’s a complete, hassle-free fix for your 2016 Spark ECM issues.
From the Diagnostic Bay
I remember a 2016 Spark that came into the shop with an intermittent no-start and a handful of communication codes (U-codes). The owner had already replaced the battery and checked the fuses. The temptation is to immediately condemn the ECM. However, with these vehicles, the first thing I always check are the main power and ground connections at the ECM connector itself. A slightly corroded ground wire can mimic complete module failure. After confirming solid voltage and grounds, we installed a pre-programmed ECM like this one, and the car fired right up and has been reliable ever since. Always verify the basics first, but when the module is truly the cause, a properly programmed replacement is the only correct repair.
Common Signs of a Failing Engine Computer
If you’re experiencing any of the following, a faulty ECM is a highly likely culprit. A failing 2016 Spark ECM can cause a wide range of problems that can be difficult to diagnose without swapping the part.
- ✔ Check Engine Light is on with no clear cause
- ✔ Engine stalling or sputtering intermittently
- ✔ Vehicle refuses to start, even with a good battery and starter
- ✔ Noticeable decrease in fuel efficiency
- ✔ Poor engine performance, hesitation, or rough idling
- ✔ Communication error codes, such as U0100 (Lost Communication with ECM/PCM)
- ✔ Internal module fault codes like P0601, P0603, or P0606
A Straightforward Guide to Installation
Installing your new ECM is a simple process that most DIY enthusiasts can complete with basic hand tools. Our VIN programming makes it a plug-and-play procedure.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Locate the ECM: On the 2016 Spark, the ECM is typically located in the engine bay, often near the firewall or the battery.
- Disconnect Connectors: Carefully unlatch and remove the electrical wiring harnesses connected to the old module. Inspect the connectors for any signs of corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New ECM: Mount your new, pre-programmed module in place and securely fasten it.
- Reconnect Everything: Plug the wiring harnesses firmly into the new ECM until they click. Reconnect the negative battery terminal.
- Final Step: Start the vehicle. It may take a moment to idle smoothly as the system re-learns. Your 2016 Spark ECM replacement is complete!

Frequently Asked Questions
Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. We handle all the programming before shipment. You just need to provide us with your vehicle’s 17-digit VIN during or after checkout. The module arrives ready to install.
Is this a simple plug-and-play installation?
Yes, because we program it to your VIN, it is designed to be a direct, plug-and-play replacement. No trip to a mechanic or dealer is required for programming.
Where is the ECM located on my 2016 Spark?
The ECM is generally found in the engine compartment. Look for a metal box with several large electrical connectors, often mounted to the firewall or near the battery tray.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original ECM (e.g., codes P0601-P0606 or communication faults), then yes, this part is the correct fix. It’s crucial to ensure the underlying problem is the module itself and not a sensor or wiring issue.
What information do you need from me?
After you place your order, we simply need your vehicle’s VIN to load the correct GM software for your specific car. This ensures perfect compatibility and performance.
