Aisin 81-40LE - Automatic Transmission (European Emissions)

DTC P0717 (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 malfunction indicator lamp (MIL) 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 MIL 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
