DTC P0089-00: (PCM, VIN M) DETECTION CONDITION AND POSSIBLE CAUSE

DESCRIPTION Spill valve control solenoid valve control circuit range/performance problem
DETECTION CONDITION Determination conditions
  • If any of the following conditions is met under condition A or condition B: Condition A:
    • The average fuel pressure on the high pressure side, measured by the fuel pressure sensor, exceeds the specified value.

      Condition B:

    • The fuel pressure decreases to the specification or less instantaneously after the fuel pressure on the high pressure side measured by the fuel pressure sensor exceeds the specification.
Preconditions Condition A:
  • Engine speed: 500 rpm or more*1
  • The fuel injection amount cumulative value after engine start is the specification or more.
  • The following DTCs are not detected:
  • Fuel pressure sensor: P0087-00:, P0088-00:, P0192-00:, P0193-00:
    • High pressure fuel pump: P0091-00:, P0092-00:

Condition B:
  • While engine is running
  • Fuel pressure sensor output voltage: 0.16-4.87 V*1 (Except U.S.A. and CANADA)
  • Fuel pressure sensor output voltage: 0.66-4.87 V*1 (U.S.A. and CANADA)
  • The following DTCs are not detected:
  • Fuel pressure sensor: P0192-00:, P0193-00:
    • High pressure fuel pump: P0091-00:, P0092-00:

*1 : Standard can be verified by displaying PIDs using M-MDS
Malfunction determination period Condition A:
  • 2 s period

Condition B:
  • Not applicable
Drive cycle
Self test type
  • CMDTC self test, KOER self test
Sensor used
  • Fuel pressure sensor
FAIL-SAFE FUNCTION
  • Limits intake air amount
  • Stops high pressure fuel pump control.
  • The upper limit of the engine speed is 2, 500 rpm.
  • The lower limit of the engine speed is 1, 000 rpm.
VEHICLE STATUS WHEN DTCs ARE OUTPUT
  • Illuminates check engine light.
POSSIBLE CAUSE
  • High pressure fuel pump connector or terminals malfunction
  • PCM connector or terminals malfunction
  • Fuel pressure sensor malfunction
  • High pressure fuel pump malfunction
  • Spill valve control solenoid valve (built-into high pressure fuel pump) malfunction
  • High pressure fuel pipe clogging
  • Fuel distributor malfunction
  • Fuel injector malfunction
  • PCM malfunction
