DTC P0722 (Non Europe or N. American Emissions)
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC P0722 Output Shaft Speed Sensor Low
Conditions for Setting the DTC
^ This DTC detects no signal of output shaft speed (OSS) sensor circuit for a long period of time. The revolution is 0-10,000 RPM.
^ The transmission control module (TCM) detects no pulse of the OSS sensor while the TCM detects 178 pulses of input shaft speed (ISS) sensor. This detection 500 times continuously.
^ D,2,L range selected
^ The input speed is 5 km/h (3 mph) or greater.
^ DTCs P0751, P0753, P0756, P0758, and P0717 are not set.
^ 25 seconds later after Neutral (N) to Drive (D) shift
Action Taken When the DTC Sets
^ The TCM will request the illumination of the hold lamp and store the DTC when the TCM detects a failure on the first ignition cycle.
^ No lockup control
^ No engine torque reduction control
^ No engagement pressure control
^ No 4th gear
^ No self-learning control
^ No prevent reverse gear control
Conditions for Clearing the DTC
^ The TCM turns off the hold lamp when no further failures are detected on the next ignition cycles.
^ The scan tool can clear the DTC from the TCM history.
^ The TCM clears the DTC from the TCM history memory after 40 consecutive ignition cycles without fault.
^ The TCM detects 250 pulses of the OSS sensor while failure detection is not achieved.
Cause of Failure
^ The wiring harness or connector between OSS sensor and TCM
^ The OSS sensor
^ The TCM
