Function Explanation (DTC Detection Outline)
WARNING: This page is about a different variant/trim than selected.
- The PCM performs diagnosis of the EGR system from the estimated EGR flow volume information.
- If the estimated EGR flow volume is larger than the specified value when all of the preconditions are met, the PCM determines a malfunction.
- The PCM performs diagnostics 1 time during 1 drive cycle. If the PCM determines a malfunction, it stores a pending code.
- If the PCM determines that the malfunction recurs from the next drive cycle, it stores a DTC and turns on the check engine light.
