About the Cardone Engine Control Module Product Line

The Cardone Engine Control Module product line focuses on delivering reliable replacement ECMs that meet OEM specifications. These modules are engineered to integrate seamlessly with your vehicle's existing systems, including powertrain and anti-theft components. The 78-9164F ECM is part of this line, ensuring compatibility and performance for Ford Focus models requiring precise engine control management.

Detailed Product Description

The Cardone 78-9164F Engine Control Module is a critical component that controls various engine functions such as fuel injection, ignition timing, and emissions control. It is designed to replace the original ECM in Ford Focus vehicles, restoring proper engine operation and drivability. This module requires proper VIN programming to match the vehicle’s identification number, especially for Chrysler PCM models with a "v" suffix, and similar considerations apply for Ford vehicles with passive anti-theft systems (P.A.T.S). Not all Ford vehicles require a P.A.T.S reset, but it is important to verify this based on your specific model and year.

Common Issues Addressed by This ECM

  • Engine misfires or poor performance
  • Check engine light related to ECM faults
  • Starting issues due to ECM or anti-theft system conflicts
  • Faulty fuel injection or ignition timing control
  • Communication errors between engine sensors and control unit

Installation Notes and Tips

  • Verify the part number 78-9164F matches your vehicle’s requirements before installation
  • Ensure VIN programming is completed if required, especially for Chrysler PCM with "v" suffix
  • Check if your Ford Focus model requires a passive anti-theft system reset
  • Use a compatible diagnostic tool such as a Tech 2 scanner for programming and resetting
  • Confirm the original ECM is the cause of the issue before replacement

While specific warranty details for part number 78-9164F should be confirmed at the time of purchase, Cardone typically offers coverage against defects in materials and workmanship.
