It is common for drivers of Ford vehicles to receive a diagnostic trouble code (DTC) of P1237, the Ford Code for a Fuel Pump Secondary Circuit Malfunction. This code is triggered when the PCM receives a signal from the FPDM that there is a fault in the fuel pump secondary circuit. It is essential to diagnose this code to determine the problem’s cause correctly. Possible causes of a P1237 code include an open or shorted FP PWR circuit, an open FPDM fuel pump return circuit, open or shorted fuel pump windings, or a locked rotor in the fuel pump. Additionally, the FPDM itself may be damaged. In order to adequately address the issue and prevent further problems, it is essential to understand the possible causes and solutions for a Ford Code P1237.

Causes and Solutions for Ford Code P1237
| Cause | Solution |
|---|---|
| An open or shorted FP PWR circuit | Test the circuit for continuity and repair or replace any damaged wiring |
| An open FPDM fuel pump return circuit | Check the circuit for any breaks and replace any broken wires |
| Open or shorted fuel pump windings, or a locked rotor in the fuel pump | Replace the fuel pump and rotor assembly |
| The FPDM is damaged | Replace the FPDM with a compatible part |
When a Ford vehicle displays a diagnostic trouble code of P1237, it is essential to understand the possible causes and solutions for the Ford Code P1237. This code is the Ford Code for a Fuel Pump Secondary Circuit Malfunction and can be caused by an open or shorted FP PWR circuit, an open FPDM fuel pump return circuit, open or shorted fuel pump windings, or a locked rotor in the fuel pump. Additionally, the FPDM itself may be damaged. To adequately address the issue and prevent future problems, it is essential to understand the possible causes and solutions for a Ford Code P1237.

An Open or Shorted FP PWR Circuit
When the PCM receives a signal from the FPDM that there is a fault in the fuel pump secondary circuit, it may be caused by an open or shorted FP PWR circuit. To address this issue, it is necessary to test the circuit for continuity and repair or replace any damaged wiring.
An Open FPDM Fuel Pump Return Circuit
A broken FPDM fuel pump return circuit can also cause a Ford Code P1237. To fix this issue, it is necessary to check the circuit for any breaks and replace any broken wires.
Open or Shorted Fuel Pump Windings, or a Locked Rotor in the Fuel Pump
If the fuel pump windings are open or shorted or the rotor is locked, it can cause a Ford Code P1237. To address this issue, it is necessary to replace the fuel pump and rotor assembly.
The FPDM is Damaged
Finally, the FPDM itself may be damaged, causing a Ford Code P1237. To fix this issue, replacing the FPDM with a compatible part is necessary.
