DTC detecting condition |
|---|---|---|
| P2586 | TC BOOST CONTROL POSITN SEN B (Turbocharger boost control position sensor B circuit) |
A voltage signal transmitted from the electric wastegate control valve position sensor (bank 2) is 4.7 V or more continuously for 5 seconds. |
POSSIBLE CAUSE
- Electric wastegate control valve position sensor
- Harness and connectors
(Electric wastegate control valve position sensor circuit is open or shorted.)
FAIL-SAFE
| Fail safe mode | Vehicle behavior |
|---|---|
| Engine output control | ECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle speed to encourage the driver to repair malfunction. Driving at 70 km/h (43 MPH) or more is possible.
NOTE:
This value is a reference value converted from engine power to vehicle speed. Actual power limitation value differs due to the malfunctioning part and driving condition. |
| Device fix mode |
|
| Others | ECM stops the electric wastegate actuator control. (Wastegate valve opens) |
