DTC P2565-00: WASTEGATE Valve Position Sensor Circuit High Input: Notes
DTC P2565:00 DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P2565:00 |
Wastegate valve position sensor circuit high input |
| DETECTION CONDITION |
- If the input voltage at the PCM terminal 1BJ is more than 4.75 V for 5 s, the PCM determines that the wastegate valve position sensor circuit is high.
MONITORING CONDITIONS
- Battery voltage: 8 V or more
- 0.5 s have elapsed after the ignition was switched ON (engine off or on)
Diagnostic support note
- This is a continuous monitor (CCM).
- The check engine light does not illuminate.
- FREEZE FRAME DATA is not available.
- Snapshot data is available.
- DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- Stop the supercharging pressure control. (fully open the wastegate valve)
|
| POSSIBLE CAUSE |
- Wastegate valve connector or terminals malfunction
- PCM connector or terminals malfunction
- Short to power supply in wiring harness between wastegate valve terminal E and PCM terminal 1BJ
- Wastegate valve position sensor power supply circuit and signal circuit are shorted to each other
- Open circuit in wiring harness between the following terminals:
- Wastegate valve terminal E-PCM terminal 1BJ
- Wastegate valve terminal C-PCM terminal 1AR
- Wastegate valve position sensor malfunction
- PCM malfunction
