## DTC P0717 Non European 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
