|P0232 2003 FORD F150 code possible causes

  • Blown Fuel Pump fuse
  • Open Fuel Pump Monitor Circuit
  • Poor fuel pump ground
  • Faulty Fuel Pump Relay
  • Damaged Engine Control Module (ECM)

|How do I fix the P0232 2003 FORD F150 code?

Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

|P0232 2003 FORD F150 code tech notes

For some FORD models:
1. Disconnect the inertia switch harness connector
2. Turn key to ON position (Engine OFF)
3. Measure voltage of circuit between inertia switch harness connector and ground
4. If battery voltage is found, replaced Inertia Switch
5. Clear codes

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.

|Cost of diagnosing the P0232 2003 FORD F150 code

Labor: 1.0

The cost of diagnosing the P0232 2003 FORD F150 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|When is the P0232 2003 FORD F150 code detected?

The code will be set if a low voltage on the control circuit of the fuel pump relay is detected by the ECM.

|What are P0232 2003 FORD F150 code possible symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)

|P0232 2003 FORD F150 code description

The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. When the ignition switch is first turned ON, the ECM energizes the fuel pump relay, which applies power to the fuel pump. The ECM enables the fuel pump relay as long as the engine is cranking or running, and crankshaft reference pulses are received. If no crankshaft reference pulses are received, the ECM de-energizes the fuel pump relay after 2 seconds. The ECM monitors the voltage on the fuel pump relay control circuit.
