A diagnostic trouble code is generated when the fault criteria are satisfied.

For the diagnostic trouble code to be cleared without further action, 40 faultless warm-upcycles must be completed.

For the CHECK ENGINE lamp (MIL) to go out by itself, 3 consecutive driving cycles must be completed without the fault recurring.

For the diagnostic trouble code to be cleared, 40 faultless warm-upcycles must also be completed.
