DTC P0089:00 (PCM, SKYACTIV-G, US) 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
- 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
- The following DTCs are not detected:
- Fuel pressure sensor: P0192:00 and P0193:00
- High pressure fuel pump: P0091:00 and P0092:00
|
| Malfunction determination period |
Condition A:
|
| Drive cycle |
|
| Self test type |
- CMDTC self test, KOER self test
|
| Sensor used |
|
| Fail-safe function |
- Limits intake air amount
