DTC P0232: Fuel Pump Secondary Circuit High

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 ignition 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 short to voltage.
Possible Causes: 
  • Inertia fuel shutoff (IFS) switch not reset or electrically open
  • Open circuit between the fuel pump and the FPM connection to the FP PWR circuit
  • Intermittent fuel pump ground
  • Fuel pump electrically open
  • Fuel pump secondary circuits short to voltage
  • Fuel pump relay contacts always closed
  • Open FPM circuit between the PCM and the connection to the FP PWR circuit
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.
