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 (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Stops the high pressure fuel pump control. Limits the 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 the following terminals: High pressure fuel pump terminal A-PCM terminal 1EE High pressure fuel pump terminal B-PCM terminal 1EF Spill valve control solenoid valve (built-into high pressure fuel pump) malfunction PCM malfunction

CAUTION:

Verify the malfunction symptom according to not only the PID value but also the symptom troubleshooting.
