Diagnostic Method: Notes

After the malfunction criteria are completed, calculate the output fluctuation value of front oxygen (A/F) sensor (with right and left) and output fluctuation value of front oxygen sensor (with right and left).

Calculate the diagnosis value when the front oxygen (A/F) sensor output fluctuation value more than specified value. (With right and left)

Diagnostic values on both sides are added and total is considered as a final diagnostic value.

Judge NG when the malfunction criteria below are completed, and judge OK when they are not completed.
