DTC P0230: Fuel Pump Primary Circuit
WARNING: This page is about a different variant/trim than selected.
P0230 - FUEL PUMP PRIMARY CIRCUIT
| Description: The PCM monitors the fuel pump (FP) circuit output from the PCM. The test fails when the FP output is commanded ON (grounded) and excessive current draw is detected on the FP circuit. The test also fails when the FP output is commanded OFF and 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. | |||
Possible Causes:

| Diagnostic Aids: A concern is present when the FP_F PID reads YES. An open circuit or short to ground can only be detected with the fuel pump commanded OFF. A short to voltage can only be detected with the fuel pump commanded ON. During the key ON engine OFF (KOEO) and key ON engine running (KOER) self-test, the fuel pump output command is cycled ON and OFF. | |||
| Application | Key On Engine Off | Key On Engine Running | Continuous Memory |
