Remanufactured ECM for Ford TaurusCardone 78-4735 is a remanufactured engine control module built for 1989-1990 Ford Taurus models with Federal Emission System calibration. It is pre-programmed at the factory for the listed application and is engineered to restore proper engine management after an ECM failure.As part of Cardone’s Engine Control Module line, this unit is remanufactured to OE-style fit and function for the Ford Taurus platform. The process focuses on correcting known failure points, validating operation, and returning the vehicle to stable drivability.Key Features Remanufactured Original Equipment-style ECM for exact vehicle fit Factory pre-programmed for the listed Ford Taurus application Critical components are re-soldered or replaced during remanufacturing 100% computer tested for electrical function and reliability On-car validation is performed to confirm durability and performance Earth-conscious remanufacturing reduces raw material and energy use versus new part production Product DetailsCardone 78-4735 is designed for drivers and technicians replacing a failed engine control module in a 1989-1990 Ford Taurus, with Federal Emission System. The module is built from reverse-engineered failure analysis, allowing Cardone to address common internal weaknesses before the unit is returned to service. This helps support consistent engine control, fuel delivery strategy, and overall drivability in the original application.This part cross-references Ford engineering numbers E9DF12A650AA and E9DZ12A650AA for the same application.Common Problems This ECM May Resolve No-start condition caused by a failed engine control module Intermittent stalling or rough running related to ECM faults Check engine concerns tied to internal control module failure Loss of proper fuel or ignition management from damaged electronics Driveability issues after confirming power, ground, and wiring integrity Installation Notes and Tips Fits 1989-1990 Ford Taurus, N/A, with Federal Emission System; ID #(s) E9DF-AA. Verify the original failure source before replacing the ECM; inspect grounds, power feeds, wiring harnesses, and related relays or solenoids. Confirm the Ford engineering ID on the original module matches the Cardone application before installation. This unit is pre-programmed at the factory for the listed application. Quality AssuranceCardone remanufactures this ECM using computer testing and application-specific validation to confirm function before release. The remanufacturing process includes re-soldering or replacement of critical internal components to improve electrical integrity and long-term reliability.
