P0230 - FUEL PUMP PRIMARY CIRCUIT
| Description: | The powertrain control module (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. | |||
| Possible Causes: |
|
|||
| Diagnostic Aids: | 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. | |||
