I had issues with the check engine light coming on repeatedly. The last time I fixed what was wrong I replaced the fuel filter then reset the error codes. I had help replacing the fuel filter and resetting the error codes. Since then I have driven 218 miles and the drive cycle is still incomplete. It said the evap system test, catalyst test, o2 sensor test, and o2 sensor heated test are all showing as incomplete. The check engine light is off and the obd2 scanner shows no pending error codes. How is this possible? Is there any thing I can do to fix this?

Hi,

These drive cycle are not indicating a fault. They require specific drive cycles so that the computer can see if these is an issue. It requires these so that it can compare these readings against a programmed set of parameters.

Attached are the drive cycles that need to happen before these monitors are complete. If you drive this way, it will try to force the monitor. Otherwise you will get them to run over time of driving. Let me know if you have questions. Thanks
