Is Your Vehicle Running Rough? It Could Be The ECM.
If your Pontiac G3, Chevy Aveo, or Cruze is experiencing frustrating issues like stalling, poor fuel economy, or an illuminated Check Engine Light that won’t go away, the root cause is often a failing Engine Control Module (ECM). As the central computer for your engine, the ECM manages everything from fuel injection and ignition timing to emissions controls. When it begins to fail, it can cause a cascade of performance problems that can be difficult to diagnose and leave you stranded. Don’t let a faulty computer dictate your vehicle’s reliability. This direct-fit ECM is the definitive solution to restore your car’s performance and peace of mind.

Where is the ECM located on my 2009 Pontiac G3?
On most vehicles like the Pontiac G3 and Chevy Aveo, the ECM is typically located in the engine bay, often mounted to the firewall, inner fender, or near the battery. Always disconnect the battery before attempting to replace it.
Is any other setup required after installation?
In some cases, a security relearn procedure (also known as a key relearn) may be necessary. This is a simple procedure that can typically be done without special tools and instructions can be easily found online for your specific model.
