(See INTAKE SHUTTER VALVE POSITION SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

•  Install/connect the part removed/disconnected during the troubleshooting procedure.

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.

―  Drive the vehicle on flat roads under the following conditions 5 times repeatedly.

1.  Idle the engine for 20 s.

2.  Accelerate in 2nd gear to 35 km/h and drive the vehicle while maintaining the speed for 25 s.

3.  Stop the vehicle and idle the engine for 20 s.

4.  Accelerate in 3rd gear to 50 km/h and drive the vehicle while maintaining the speed for 50 s.

5.  Stop the vehicle and idle the engine for 20 s.

―  Stop the engine.

•  Perform the DTC inspection for the PCM.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction recurs, replace the PCM, then go to the next step.
