DTC P0092-00: Fuel Pressure Regulator Control Circuit High Input: Notes

DTC P0092:00 (PCM, VIN Y) 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
