EXHAUST SHUTTER VALVE POSITION SENSOR INSPECTION [SKYACTIV-D 1.8]

id0140s1538300

DTC Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Perform the KOEO self test.

3.  Perform the DTC inspection using the M-MDS. (See DTC INSPECTION.)

•  If any DTC related to the exhaust shutter valve position sensor is present, repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D)].)

Note

•  The exhaust shutter valve position sensor is built into the exhaust shutter valve actuator. When replacing the exhaust shutter valve position sensor, replace the exhaust shutter valve actuator.

PID/DATA Monitor Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine off).

3.  Access and monitor the PCM PID/DATA monitor item [EX_SHUT_VLV_ACT] and PCM simulation item [EX_SHUT_VLV_DSD]. (See PID/DATA MONITOR INSPECTION.)(See SIMULATION INSPECTION.)

4.  Verify that the PID [EX_SHUT_VLV_ACT] value increases linearly, while increasing the opening angle of the exhaust shutter valve using the active command mode function of [EX_SHUT_VLV_DSD].

•  If the PID [EX_SHUT_VLV_ACT] does not increase according to the exhaust shutter valve opening angle, inspect the exhaust shutter valve.

(See EXHAUST SHUTTER VALVE INSPECTION [SKYACTIV-D 1.8].)

•  If the PID [EX_SHUT_VLV_ACT] increases increase linearly according to the exhaust shutter valve opening angle, the exhaust shutter valve is normal.
