Engine Control Module (ECM)

The Honda OEM 37820-P28-A52 is a refurbished Engine Control Module (ECM) intended as a replacement for specific Honda Civic models. This unit is compatible with the 1994, 1995, and 1996 model years, specifically for vehicles equipped with a 1.6L engine, an automatic transmission, and Federal emissions standards. This ECM is offered as a pre-owned, rebuilt, and tested component. Some sources indicate it is a "plug and play" unit that does not require additional programming and will work with the vehicle's original keys. However, another source suggests it "likely needs to be programmed by a dealer." Buyers are advised to verify programming requirements for their specific application. Common symptoms of a failing ECU that this module can address include rough idle, cylinder misfires, poor acceleration, issues with OBD communication, non-functional A/C, starting failures, and transmission shifting problems. The product comes with varying warranty information depending on the seller, with one offering a 1-year limited warranty and another a 2-year warranty (with an optional 5-year upgrade). A core deposit may be included in the price, which is refundable upon return of the original unit.
