P0089-00 (PCM (PYUL)) 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 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 and P0193-00
- High pressure fuel pump: P0091-00 and P0092-00
Condition B:
- While engine is running
- Fuel pressure sensor output voltage: 0.51-4.87 V *1

|
| Sensor used |
|
| Fail-safe |
- Limits intake air amount
- Stops high pressure fuel pump control
- The upper limit of the engine speed is 2, 500 RPM.
