Conditions for Setting the DTC

P0722

The transmission output speed is 70 RPM or less for 4.5 seconds.

P0723

* The transmission output speed is 210 RPM or greater for 0.2 second.

* The transmission output speed drops 650 RPM for greater than 1.5 seconds and does not recover.

Action Taken When the DTC Sets

* DTCs P0722 and P0723 are Type A DTCs.

* The TCM freezes transmission adaptive functions.

* The TCM turns OFF the high sided driver, which turns OFF all solenoids.

* The TCM commands maximum line pressure.
