DTC P0092-00; Fuel Pressure Regulator Control Circuit High Input: Notes
DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0092:00 |
Fuel pressure regulator control circuit high input |
| DETECTION CONDITION |
- When the PCM turns the spill valve control solenoid valve on but the spill valve control solenoid valve circuit voltage is high for 5 s, the PCM determines that the spill valve control solenoid valve control circuit has a malfunction.
MONITORING CONDITIONS
- The following conditions are met:
- Engine speed: 5, 700 rpm or less
- Battery voltage: 10.5 V or more
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA/Snapshot data is available.
- DTC is stored in the PCM memory.

| FAIL-SAFE FUNCTION |
- Stops high pressure fuel pump control
- Limits intake air amount
|
| POSSIBLE CAUSE |
- High pressure fuel pump connector or terminals malfunction
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between high pressure fuel pump terminal B and PCM terminal 1EF
- Spill valve control solenoid valve (built-into high pressure fuel pump) malfunction
- PCM malfunction
