Diagnostic Trouble Code (DTC) P1237 or P1238 indicate that the Fuel Pump Driver Module (FPDM) has detected a fuel pump secondary circuit fault. This is due to either an intermittent or hard fault concern. This DTC is set when the PCM receives a 75% duty cycle signal from the FPDM on the FPM circuit. The only difference between the DTC P1237 and P1238 is that the P1237 is an MIL DTC.

Possible causes:

-- Open or shorted FP PWR circuit.

-- Open fuel pump ground circuit to FPDM.

-- Open or shorted circuit in fuel pump.

-- Locked fuel pump rotor.

-- Damaged FPDM.
