Part Description
This used OEM engine control module (ECM) was removed from a 2002 Acura CL equipped with the 3.2L V6 engine and federal emissions system. The ECM has been professionally inspected and tested to ensure proper functionality. This electronic brain box is currently on our shelf and ready to ship immediately.
The engine control module is the central computer that manages your vehicle’s engine performance, fuel injection, ignition timing, and emissions systems. When an ECM fails, you may experience poor fuel economy, rough idling, stalling, or check engine lights. Common causes of ECM failure include electrical surges, moisture damage, or internal component wear over time.

Frequently Asked Questions
Will this ECM work in my 2002 Acura CL without programming?
Most ECMs require programming to match your vehicle’s VIN and security system. We recommend having it programmed by a qualified technician or dealership after installation.
How do I know if my engine control module is bad?
Common symptoms include check engine lights, poor fuel economy, rough idling, stalling, or failure to start. A diagnostic scan can confirm ECM-related trouble codes.
What’s the difference between an ECM and PCM?
ECM (Engine Control Module) manages engine functions only, while PCM (Powertrain Control Module) controls both engine and transmission. This Acura CL uses a separate ECM for engine management.
Can I install this ECM myself?
Installation involves removing the lower center dash panel and disconnecting electrical connectors. While mechanically simple, programming requires specialized equipment and should be done by a professional.
What causes engine control modules to fail?
Common causes include electrical surges from jump-starting, moisture intrusion, vibration damage, and normal wear of internal components over time. Power supply issues can also damage ECMs.
