P0232 1999 Ford F150 Code - Fuel Pump Secondary Circuit High
Quick Answer
The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. Common causes include Blown Fuel Pump fuse, Open Fuel Pump Monitor Circuit, Poor fuel pump ground. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0232 1999 Ford F150 Description
What are the Possible Causes of the DTC P0232 1999 Ford F150?
- Blown Fuel Pump fuse
- Open Fuel Pump Monitor Circuit
- Poor fuel pump ground
- Faulty Fuel Pump Relay
- Damaged Engine Control Module (ECM)
How to Fix the DTC P0232 1999 Ford F150?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
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.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0232 1999 Ford F150 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
