WASTEGATE VALVE POSITION SENSOR INSPECTION [SKYACTIV-G 2.5T]

id0140h0498800

Note

•  The wastegate valve position sensor is integrated in the wastegate valve actuator.

•  The wastegate valve actuator cannot be removed as a single unit. When replacing the wastegate valve actuator, replace it together with the dynamic pressure turbo as a single unit.

Voltage inspection

1.  Switch the ignition ON (engine off).

2.  Measure the voltage at the wastegate valve actuator terminal E.

•  If the voltage is within the specification, go to the next step.

•  If the voltage is not within the specification, replace the dynamic pressure turbo. (See DYNAMIC PRESSURE TURBO REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)

3.  Connect the M-MDS to the DLC-2.

4.  Start the engine.

5.  Access the PID/DATA monitor item WGP and simulation item WGV using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].)

6.  Verify that the WGP monitor value conforms to the WGV monitor value when the simulation item WGV is set from 0 % to 100 %.

•  If the voltage does not increase, replace the dynamic pressure turbo. (See DYNAMIC PRESSURE TURBO REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)
