DTC P0717: Turbine Speed Sensor Circuit No Signal [08/2015 - 08/2019]: Description
WARNING: This page is about a different variant/trim than selected.
This sensor detects the rotation speed of the turbine which indicates the input speed of the transmission. By comparing the input turbine speed signal NT with the counter gear speed sensor signal SP2, the ECM detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure according to various conditions. As a result, the gears shift smoothly.
| DTC Code | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0717 | All conditions are met for 5 sec. or more (1-trip detection logic): (a) Gear change: not performed. (b) Gear position: 4th or 5th. (c) T/M input shaft speed: 300 rpm or less. (d) T/M output shaft speed: 1000 rpm or more. (e) Park/neutral position switch: R input signal is OFF. (f) Shift solenoid valves and park/neutral position switch: in normal operation. |

Reference: Inspect using an oscilloscope.
Check the waveform of the ECM connector.
