P1232 - Low Speed Fuel Pump Primary Circuit Malfunction

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.
P1232 - LOW SPEED FUEL PUMP PRIMARY CIRCUIT MALFUNCTION

Description:  The PCM monitors the low speed fuel pump (LFP) primary circuit output from the PCM. The test fails if: the LFP circuit is commanded ON (grounded), and excessive current draw is detected on the LFP circuit; or, the LFP circuit is commanded OFF, and voltage is not detected on the LFP circuit. The PCM expects to detect VPWR voltage through the low speed fuel pump relay coil to the LFP circuit.
Possible Causes: 
  • Open or shorted low fuel pump (LFP) circuit.
  • Open VPWR to the low speed fuel pump relay.
  • Damaged low speed fuel pump relay.
  • Damaged PCM.
Diagnostic Aids: 
  • An open circuit or short to ground can only be detected with the low speed fuel pump.
  • A short to power can only be detected with the low speed fuel pump commanded ON.
  • During the KOEO and KOER self-test, the low speed fuel pump output command is cycled on and off.
