P0089:00 (PCM - VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location Spill valve control solenoid valve system: Characteristic malfunction
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 high 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 high 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:
    • High fuel pressure sensor: P0087:00, P0088:00, P0192:00 and P0193:00
    • High pressure fuel pump: P0091:00 and P0092:00

Condition B: 
  • While engine is running
  • High fuel pressure sensor output voltage: 0.51-4.87 V *1
  • The following DTCs are not detected:
    • High fuel pressure sensor: P0192:00 and P0193:00
    • High pressure fuel pump: P0091:00 and 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
  • 1
Self test type
  • CMDTC self test, KOER self test
Sensor used
