P0232: Fuel Pump Secondary Circuit High

WARNING: This page does not describe the selected car, but rather 30 other vehicles, including the 2004 Mercury Sable, 2004 Mercury Mountaineer, 2004 Mercury Monterey, 2004 Mercury Marauder, and 2004 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.
P0232 - FUEL PUMP SECONDARY CIRCUIT HIGH

Description: 
NOTE: For natural gas applications, the following description applies to the fuel shutoff valve monitor (FSVM) and the fuel shutoff valve power (FSV PWR) circuits. The 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 will go high if, with the key ON and the fuel pump commanded OFF, the FPM/FP PWR circuit loses its path to ground through the fuel pump. The FPM circuit will also go high if the FPM/FP PWR circuit is shorted to power.
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.
  • Poor fuel pump ground.
  • Fuel pump electrically open.
  • Fuel pump secondary circuits short to power.
  • Fuel pump relay contacts always closed.
  • Open FPM circuit between the PCM and the connection to the FP PWR circuit.
  • Damaged low speed fuel pump relay or concern with related circuits (if equipped).
  • Damaged PCM.
Diagnostic Aids:  Continuous memory 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 (fuel system test or prime procedure).
