The ‘EAC FAIL’ message is a very common problem for the Fiesta 1.4 and will also cause the engine to run in limp mode severely reducing engine power. Often the vehicle will have very little throttle response before limp mode is activated.
Diagnosing this fault can be difficult as the fault codes generated can be very misleading, common fault codes reported those for acceleration pedal position (APP) sensors and throttle valve housing.
Despite the fault codes blaming the throttle pedal or throttle housing these are not usually the cause of the problem.
If the throttle housing and circuit has been thoroughly checked and pedal position sensor/circuit is OK, then the engine ECU is likely to be the cause of the EAC FAIL message.
