P0232 - Fuel Pump Secondary Circuit High

WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
P0232 - FUEL PUMP SECONDARY CIRCUIT HIGH

Description:  The powertrain control module (PCM) monitors the fuel pump monitor (FPM) circuit. This test fails when the PCM detects voltage on the FPM circuit while the fuel pump is commanded OFF. The FPM circuit is wired to a pull-up voltage inside the PCM. The FPM circuit goes high if, with the key ON, engine OFF and the fuel pump commanded OFF, the FPM/FP PWR circuit loses its path to ground through the fuel pump. The FPM circuit also goes high if the FPM/FP PWR circuit is shorted to voltage.
Possible Causes: 
  • Fuel pump relay
  • FPM circuit open in the harness
  • FPM circuit short to voltage in the harness
  • FP circuit short to ground in the harness
  • Fuel pump ground circuit open
  • Fuel pump
Diagnostic Aids:  Continuous memory DTC P0232 can be set if the IFS switch is tripped then reset, or if the fuel pump circuit is activated when the PCM expected the circuit to be off. This DTC may set during a fuel system test or prime procedure.
