Ford Fiesta 2002 - 2008 ECU failures
Ford Fiesta 2002 – 2008 misfiring on two cylinders.
The 2 cylinder misfire is the most common fault caused by the engine ECU for the fifth generation Fiesta (2002 – 2008), the fault is originally caused by a faulty ignition coil pack that spikes voltage back to the engine ECU and blows the ignition output circuits for 2 of the cylinders.
Depending on the severity of the damage caused, the engine ECU vehicle may also prevent the starting of the vehicle.
When scanning the vehicle for fault codes with diagnostics readers fault codes will be found for ignition coil circuits A and B.
