After Ford recognized this problem, they offered a slightly redesigned replacement part which is not in direct contact with the steel frame. Sure, without fuel, that mighty Fort Triton wonвЂ™t work.ДЄs the fuel pump driver module is attached to the frame (at the rear end) with only two screws, replacing it is a DIY job. Over time, vibrations, salt, and water do irreparable damage to the casing and dirt enters the driver module causing short circuits and making permanent damage to the smart junction box. As its surface is exposed to the elements, salt, water, and dirt build up on its aluminum casing and cannot be washed away as it is in contact with the steel frame. In the first place, the problem happens because the fuel pump driver module is directly attached to the steel frame. This tends to happen on Ford trucks driving on highways (I donвЂ™t have to stress that losing power there is super dangerous). Failure of the fuel pump driver module usually cuts off the petrol feed to the engine which, of course, causes the engine to turn off, thus cutting power to all essential systems. This problem is typical for the Ford F-150 with a 5.4 Triton engine. In some cases, faulty factory crimps at the relay box could be causing this issue.5.4 Triton Engine Failure of the Fuel Pump Driver Module If the problem persists, technicians will now test the wiring crimp connectors. If there is sufficient power, they will re-jumper the relay contacts and then check for power coming from the fuse box and straight to the pump. If that doesnвЂ™t fix the problem, technicians will now check for power coming into the relay. If the connector is not getting power, technicians will pull the fuel pump relay (or change I with another relay with the same part number) or jumper the relay contacts to power the pump. If both things still donвЂ™t work, technicians will check for power at the fuel pump connector. Next, they reset the inertia switch manually. To check for this code, technicians usually start by checking the fuel pump fuse.

Poor electrical connection in FDPM (Fuel Pump Driver Module) circuit.

Open or shorted FDPM (Fuel Pump Driver Module) harness.

Faulty IFS (Inertia Fuel Shutoff) switch.

IFS (Inertia Fuel Shutoff) switch needs to be reset.

Some of the most common possible causes include:

If this fails (the PCM stops receiving the duty signal), then the Error Code P1233 will set.ДЄs said earlier, this error code could be caused by a lot of factors. With the key on, the FDPM sends duty cycle signal to the PCM continuously through FPM circuit. The PCM (Powertrain Control Module, also known as ECM or engine control module in other vehicles makes) monitors the FPM (Fuel Pump Monitor) circuit from the FDPM (Fuel Pump Driver Module).

The most common symptom and usually the only symptom for this error code is the activation of the Check Engine light and the registration of the error code. This could be caused by two primary reasons that interfere with fuel pump startup вЂ“ the fuel pump relay, or the inertia switch. DefinitionД®rror Code P1233 is set when the fuel pump is not starting up correctly. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another. This error code is a generic trouble, meaning it applies to all vehicles equipped with OBD-II system, especially vehicles made since 1996 up to present. This means the fuel pump is not starting up correctly, which could be caused by problems with the FPDM (fuel pump driver module). Error Code P1233 is defined as Fuel Pump Driver Module Disabled Or Off Line.
