Focus and Mondeo ECU fault

Ford Focus / Mondeo ECU common misfire fault

 

This is a very common fault for the 1.4 - 2.0 Ford Focus (Mk I) and Mondeo (Mk II & III). When the ECU fails it causes a constant misfire on two of the cylinders.

This fault is usually caused by a faulty coil pack on the vehicle which in turn damages the internal circuitry of the engine ECU and causes this misfire.

Other, but less common, faults for this engine ECU include non-start or no spark and faults with the charging system.

 

Once this damage has been done to the ECU the faults will remain permanent, however we offer a complete ECU rebuild to resolve this issue within 2-3 working days and get you back on the road as soon as possible.

 

Please note:

This common fault of misfire on two cylinders or complete non start is often caused by the ignition coil pack shorting out on the vehicle - it is very important that the ignition coil pack is replaced at the same time as refitting your ECU after it has been repaired - or you faulty coil pack may damage the repaired ECU.

  • Misfire on two cylinders
