Part Description
This engine control module (ECM) was removed from a 2004 Honda Pilot and is designed for California emissions systems. The unit has been professionally inspected and tested to ensure proper functionality. It is currently on our shelf and ready for immediate shipment to get your Honda Pilot back on the road.
The engine control module is the brain of your vehicle’s engine management system, controlling fuel injection, ignition timing, emissions systems, and other critical engine functions. When an ECM fails, symptoms include poor engine performance, stalling, rough idling, or the vehicle may not start at all. Replacing a faulty ECM with a quality used OEM unit like this one can restore proper engine operation at a fraction of the cost of a new part.
