This engine control module (ECM) was removed from a 2009 Honda Accord EX with 2.4L engine and automatic transmission. The electronic control unit has been inspected and tested to ensure proper functionality. Located in the left front engine compartment, this ECM carries California emissions certification ID 37820-R43-L56 and is currently on our shelf ready for immediate shipment.
The engine control module serves as the brain of your vehicle’s engine management system, controlling fuel injection, ignition timing, emissions systems, and other critical engine functions. ECMs commonly fail due to electrical surges, water damage, or internal component degradation over time, causing symptoms like rough idle, poor fuel economy, check engine lights, or no-start conditions. A functioning ECM is essential for proper engine operation and emissions compliance.

I even received a call back, which I really appreciated. Everyone I spoke with was friendly and patient, and I never felt brushed off. I truly felt taken care of. Highly recommend if you want knowledgeable people who actually care about helping you. Kristy Thanks Guys!
Drove from Connecticut to get here. Had parts for a relatively rare car that dozens of other places didn't have. I got a hood, fender and bumper cover that were in near mint condition for a fifteen year old car. They pulled all the parts for me and had everything ready within an hour. Very reasonably priced. Highly recommend
