System Wiring Diagram

Function Explanation (DTC Detection Outline)

• The PCM detects the NOx concentration in the exhaust gas based on the NOx sensor signal.

• If the NOx value, which fluctuates according to the engine operation conditions, is way over the percentage indicating out of normal range, the PCM stores a DTC.

Repeatability Verification Procedure

1. Perform the "COMPULSORY DIESEL PARTICULATE FILTER REGENERATION". (See COMPULSORY DIESEL PARTICULATE FILTER REGENERATION [SKYACTIV-D 1.8].)

2. Idle the engine for 3 min.
