System Wiring Diagram

• Not applicable

Function Explanation (DTC Detection Outline)

• The PCM diagnoses the large-type turbo system performance by comparing the target air charging pressure with the actual.

• The PCM uses the manifold absolute pressure sensor to monitor the intake manifold pressure during boost control as the actual air charging pressure.

• When the monitoring conditions are met during boost control, the PCM compares the target air charging pressure with the actual. If the actual air charging pressure is higher than the specification for the target air charging pressure, the PCM determines an excess air charging malfunction.

• The PCM performs diagnosis when each of the preconditions during drive cycle is met. If a malfunction is detected, the malfunction detection counter begins counting up. The value of the malfunction detection counter is maintained while the preconditions are not being met. If the cumulative value of the malfunction detection counter exceeds the threshold during the first drive cycle, a malfunction is determined and a pending code is stored.

• If the PCM determines that the malfunction recurs from the next drive cycle and thereafter, it stores a DTC and turns on the check engine light.

Repeatability Verification Procedure

Caution

• When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.

• While performing this step, always operate the vehicle in a safe and lawful manner.

1. Access the following PIDs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].)

― MAP_DSD

― MAP

― REGVP_DSD

2. Start the engine and warm it up completely.

3. Accelerate for 20 s with all of the following conditions met:

― Gear position: 2nd

― Engine speed: 2,000—4,500 rpm

4. Verify the difference between the target air charging pressure and the actual air charging pressure while the target value (PID: REGVP_DSD) of the regulating valve position is less than 5 mm {0.2 in}, and verify that the pressure difference of 30 kPa {0.31 kgf/cm², 4.4 psi} or more does not continue for 3 s.

System Wiring Diagram

• Not applicable

Function Explanation (DTC Detection Outline)

• The PCM diagnoses the large-type turbo system performance by comparing the target boost pressure with the actual.

• The PCM uses the manifold absolute pressure sensor to monitor the intake manifold pressure during boost control as the actual boost pressure.

• If the PCM determines that the malfunction recurs from the next drive cycle and thereafter, it stores a DTC.
