DTC P0717 (Non Europe or N. American Emissions)
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC P0717 Input Speed Sensor Circuit Low Voltage
Conditions for Setting the DTC
^ This DTC detects no signal of input shaft speed (ISS) 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 ISS sensor while the TCM detects 4 pulses of output speed sensor. This detection 1,000 times continuously.
^ D,2,L range selected
^ The engine revolution is 400 RPM or greater.
^ DTCs P0751, P0753, P0756, and P0758, are not set.
^ The output revolution is 775 RPM or greater.
^ 25 seconds later after Neutral (N) to Drive (D) shift
^ 10 seconds later after changing the gear
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 timing solenoid control N-D
^ After failure decision : emergency mode
Conditions for Clearing the DTC
^ The TCM turns OFF the hold lamp when no further failures are detected on the next ignition cycle.
^ 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 ISS while failure detection is not achieved.
Cause of Failure
^ The wiring harness or connector between ISS sensor and TCM
^ The ISS sensor
^ The TCM
