DTC P0232:00: Notes
WARNING: This page is about a different variant/trim than selected.
| DTC P0232:00 |
Fuel pump secondary circuit high |
| DETECTION CONDITION |
- The powertrain control module (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 goes high if, with the ignition ON, engine OFF and the fuel pump commanded OFF, the FPM/FP PWR circuit loses its path to ground through the fuel pump. The FPM circuit also goes high if the FPM/FP PWR circuit is short to voltage.
|
| POSSIBLE CAUSE |
- Open circuit between the fuel pump and the fuel pump monitor connection to the fuel pump power supply circuit
- Intermittent fuel pump ground
- Fuel pump electrically open
- Fuel pump secondary circuits short to voltage
- Fuel pump relay contacts always closed
- Open fuel pump monitor circuit between the PCM and the connection to the fuel pump power supply circuit
- PCM malfunction
