This Engine Control Module (ECM) was removed from a 2009 Honda Accord donor vehicle and has been professionally inspected for functionality. The ECM is the electronic brain box that manages your engine’s performance, fuel injection, ignition timing, and emissions systems. This unit is specifically configured for 3.5L engines with automatic transmission and California emissions requirements. The part has been tested and is currently on our shelf ready for immediate shipment.
The Engine Control Module is a critical component that can fail due to electrical surges, water damage, or internal circuit board deterioration over time. When your ECM fails, you may experience symptoms like rough idling, poor fuel economy, engine stalling, or the check engine light staying on. A faulty ECM can also prevent your vehicle from starting altogether. Replacing a failed ECM with a quality used OEM unit like this one can restore your Honda’s performance and reliability at a fraction of the cost of a new module.
At 603 Auto Salvage, we maintain an inventory of over 50,000 used auto parts from more than 1,100 vehicles, ensuring we have the components you need to keep your vehicle running. Our experienced team carefully inspects each part before it goes on the shelf.

I'm replacing damaged panels on my 2006 Ridgeline on a tight budget so I may quickly sell it and they were so helpful and priced better than anyone else in the area. Raised a glass of scotch for these ladies! Thanks again!
Great service! The best price and condition for the Porsche Cayenne parts needed to finish the job. Radiator core support and headlight fit perfectly!
Drove from new york, Julie was a sweetheart asked questions to make sure that my ECU was the proper part number and was compatible with my manual Accord, price was phenomenal I highly recommend them for any parts your car may need. Definitely the best salvage yard around
Great experience at 603 Auto Salvage! ⭐️ The owner and employee were both extremely helpful and easy to work with. I was able to find everything I needed in one stop — about seven different items — which saved me a lot of time and hassle. Good selection, fair pricing, and friendly service. Definitely recommend checking them out if you're looking for parts. I’ll be back again! 👍🔧🚗

I had a great experience. They didn’t just look up the part I needed they took the time to explain how to install it and made sure I understood everything.

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
Exceptional service, large selection of parts, will come back if more Audi parts are needed. A++
