Is Your Chevrolet Spark Running Rough, Stalling, or Showing a Check Engine Light?
As a technician with over two decades of experience under the hood, I’ve seen countless vehicles crippled by a faulty Engine Control Module (ECM). A failing ECM isn’t just an inconvenience; it’s the root of frustrating, hard-to-diagnose problems like poor fuel economy, erratic engine behavior, shifting issues, and even no-start conditions. Your 2014-2015 Spark relies on this module for everything from fuel mixture to ignition timing. When it fails, your car’s performance and reliability go with it.
This isn’t just another part. This is a complete, ready-to-install solution. We take a genuine OEM-quality Engine Control Module and flash it with the latest, most stable software from GM, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN). This means you get a component that’s not just a replacement, but a restoration of your vehicle’s original operating parameters.
Real-World Diagnosis: A Customer’s Story
“A customer’s 2015 Chevy Spark came into my shop last week with these exact symptoms. It had a persistent check engine light (P0606 – ECM Processor Fault), was hesitating on acceleration, and the fuel mileage had dropped significantly. After confirming power and ground at the module were solid, we knew the internal processor was failing. We installed one of these VIN-programmed modules, and it was like a new car. The codes cleared, the engine ran smoothly, and the customer was thrilled to have their dependable daily driver back without a costly trip to the dealer.”

Simple Installation: Get Back on the Road Fast
You don’t need to be a master mechanic to install this part. With basic tools, you can have your Spark running right in your own driveway.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting work.
- Locate Your Old ECM: On the 2014-2015 Spark, the ECM is typically located in the engine bay, often near the battery or against the firewall.
- Disconnect the Harnesses: Carefully unclip the locking tabs on the electrical connectors and pull them straight out. Avoid pulling on the wires themselves.
- Swap the Modules: Unbolt the old ECM from its mounting bracket and secure the new one in its place.
- Reconnect Everything: Firmly plug the electrical connectors back into the new module until they click. Reconnect your battery terminal.
- Final Check: Start the vehicle. It may run slightly differently for the first few miles as it completes its internal relearn processes.
Expert Pro Tip: Ensure a Perfect Connection
Before plugging in your new ECM, take 60 seconds to inspect the vehicle’s harness connectors. Look for any signs of green or white corrosion on the pins. If you see any, use a small nylon brush and a dedicated electronics contact cleaner to gently scrub them clean. A poor pin connection is a leading cause of intermittent issues and can even damage a new module over time.
