DTC P0717: Input Speed Sensor Circuit No Signal; DTC P07BF: Input/Turbine Speed Sensor "A" Circuit Low; DTC P07C0: Input/Turbine Speed Sensor "A" Circuit High [11/2021 - ]: Procedure

1. Turn the engine switch off.
2. Connect the Techstream to the DLC3.
3. Turn the engine switch on (IG).
4. Turn the Techstream on.
5. Enter the following menus: Powertrain / ECT / Data List / SPD (NT), NT Sensor Voltage.
6. Read the Data List according to the display on the Techstream.

   Powertrain > ECT > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   SPD (NT)	Input shaft speed	Min.: 0 rpm Max.: 12750 rpm	Lock-up is ON (after warming up engine): Input turbine speed (NT) is equal to engine speed OFF (idling with shift lever in N): Input turbine speed (NT) is nearly equal to engine speed	Data is displayed in increments of 50 rpm
   NT Sensor Voltage	NT sensor voltage	Min.: 0.000 V Max.: 5.000 V	Idling: 0.1 to 1.9 V	-
