Code P0230 1999 Ford F150 Description

The P0230 diagnostic trouble code (DTC) for a 1999 Ford F150 indicates a Fuel Pump Primary Circuit Malfunction. This code is triggered when the powertrain control module (PCM) detects an issue with the fuel pump's primary circuit. The fuel pump is responsible for delivering fuel from the tank to the engine, and any malfunction in its primary circuit can lead to significant performance issues.

Tech Notes for P0230 1999 Ford F150

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 (FSV) circuit.

The PCM monitors the fuel pump (FP) circuit output from the PCM. The test fails if: With the FP output commanded ON (grounded), excessive current draw is detected on the FP circuit; or with the FP output commanded OFF, voltage is not detected on the FP circuit (the PCM expects to detect VPWR voltage coming through the fuel pump relay coil to the FP circuit).

When is the Code Detected?

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