Diagnostic Method
WARNING: This page is about a different variant/trim than selected.
Measure the pressure in the following procedures when the enable conditions are completed, and then diagnosis by calculating the result.
- PMOF1 is equal to the intake manifold pressure at enable condition completed, and EGR target step is set to 50 steps (almost fully opened).
- PMON is equal to the intake manifold pressure in 1 second after EGR target step is set 50 steps (when enable conditions are completed), and EGR target step is set to 0 step.
- PMOF2 is equal to the intake manifold pressure in 1 second after EGR target step is set to 0 step (in 2 seconds after enable conditions are completed).
- Calculate the judged value using the following formula.
Judged value = [PMON - (PMOF1 + PMOF2)/2]
Judge NG when the malfunction criteria bellows are completed. Judge OK and clear NG when the malfunction criteria bellows are not completed.
