DTC P0092; Pcm Fuel Pressure Regulator Control Circuit High Input: Notes

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
DETECTION CONDITION & 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.
  • 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
G11550262
CAUTION:
  • Verify the malfunction symptom according to not only the PID value but also the symptom troubleshooting.
