DTC P0717 Non European Emissions

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 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
    • 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 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 ISS while failure detection is not achieved.

Cause of Failure
    • Wiring harness or connector between ISS sensor and TCM
    • ISS sensor
    • TCM
