What causes the EAC to fail on a Ford Fusion?
What causes the EAC to fail on a Ford Fusion?
A common cause of the EAC FAIL in the Ford Fiesta V and Ford Fusion is a defective throttle body (and specifically the throttle position sensor). To be 100% sure that the throttle body is the cause of the malfunction, it is best to study the live data.
What causes a Ford Fiesta EAC to fail?
The EAC fail can have different causes. The car model (type) can also be of great importance. Therefore we will describe the common causes of the EAC fault code below: With the Ford Fiësta V and Fusion produced before June 30, 2002, the ECU (also known to Ford experts as the ‘PCM’ or powertrain control module) is often the cause of the EAC fail.
What does EAC fail mean in a car?
What does ‘EAC fail’ mean? The term EAC stands for Electronic Accelerator Control, which means that there is a problem with the transmission of the electronic signal from the accelerator pedal. This problem is mainly known in the following cars: Mazda 2 DY (2003-2007)
What to do if your Mazda EAC fails?
To do this, remove the throttle body from the inlet manifold, remove the inlet air hose, unscrew the torx screws, disconnect the connector and look for the serial number and the product date. If the serial number is less than 400 000, the throttle body is very likely to be defective.

What’s the problem with the Ford Fiesta EAC fail?
Problem: Loss of power and EAC FAIL displayed. Solution: The EAC FAIL relates to the electronic accelerator control. Vehicles that trigger diagnostic fault codes (DTCs) / fault codes P2138 with P2122, P2123 or P2127 a common problem is the PCM (powertrain control module = ECM = engine control module) electrical connector.

What’s the Diagnostic fault code for a Ford Fiesta?
Vehicles that trigger diagnostic fault codes (DTCs) / fault codes P2138 with P2122, P2123 or P2127 a common problem is the PCM (powertrain control module = ECM = engine control module) electrical connector. Check the electrical connector for the PCM for damage to the terminals and pins. Replace or repair as necessary.
What should I do if my ECU fails?
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. We offer a full rebuild on these ECU’s within 1-2 working days and return the ECU back to you without the need for reprogramming once you receive it back.

What causes EAC fail message on Ford Fiesta?
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.
