This Engine Control Module (ECM) was removed from a 2003 Honda Civic EX with 1.7L SOHC VTEC engine and automatic transmission. The electronic control unit was located behind the glove box in the donor vehicle and has been professionally inspected for proper function. This OEM Honda part is currently on our shelf and ready for immediate shipment.
The Engine Control Module is the brain of your Honda’s fuel injection and ignition systems, managing everything from air-fuel mixture to timing advance. Common reasons for ECM replacement include electrical failures, water damage, or internal circuit board deterioration that can cause poor performance, stalling, or no-start conditions. A faulty ECM often triggers multiple check engine lights and can leave your vehicle inoperable.

Yes, most Honda ECMs require programming to match your vehicle’s VIN and immobilizer system. This should be done by a qualified Honda technician or automotive locksmith with the proper equipment.
Common symptoms include engine stalling, poor fuel economy, multiple check engine lights, rough idle, or complete no-start conditions. A diagnostic scan can help confirm ECM-related fault codes.
Remove the glove box assembly, locate the ECM mounted on the passenger side firewall, disconnect the main wiring harness connectors, and remove the mounting bolts. Always disconnect the battery first.

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! 👍🔧🚗

The customer service at 603 was great. They found the part I needed very quickly and promptly notified me when it was ready to be picked up. There wasn’t any other place in the area that had what I needed. The price was very good also. I will be using them again for sure.
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. 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
