DTC P0715: Input/Turbine Speed Sensor "A" Circuit; DTC P0717: Input/Turbine Speed Sensor "A" Circuit No Signal: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Engine and ECT / Data List.
5. In accordance with the display on the Techstream, read the Data List.

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   SPD (NT)	Input turbine speed/ min.: 0 RPM max.: 12750 RPM	Lock-up ON (After warming up engine): Input turbine speed (NT) equal to engine speed	-
   		Lock-up OFF (Idling at P or N position): Input turbine speed (NT) nearly equal to engine speed
   		Vehicle stopped in R position: 0 RPM
   NT Sensor Voltage	Input speed sensor output voltage/ min.: 0 V max.: 4.999 V	Engine idling speed (Vehicle stopped in shift lever P or N position) Constantly changes between 0.8 to 1.6 V and 2.4 to 3.2 V	-

   RESULT
   
   

   Result	Proceed to
   Data display is not within Normal Condition range	A
   Data display is within Normal Condition range	B

B → See step   4 

A: Go to next step 

1. Remove the transmission revolution sensor (NT). Refer to REMOVAL and then connect the battery.
2. Wave a magnetic object left and right in front of the transmission revolution sensor tip (5 mm gap or closer) to change the high/low signals while measuring the current.

   NOTE:

   Make sure to wave the magnetic object during the inspection. Current will not change without waving the magnetic object as indicated by the arrow in the illustration.

3. Measure the current according to the value(s) in the table below.

   Standard Current

   Tester Connection	Condition	Specified Condition
   1 (NTO) - 2 (NTB)	Low signal	4 to 8 mA
   	High signal	12 to 16 mA

   *1	Battery (12 V)
   *2	Ammeter
   *a	Component without harness connected [transmission revolution sensor (NT)]
   *b	5 mm gap or closer

NG → See step   6 

OK: Go to next step 

1. Disconnect the B8 ECM connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   B16-1 (NTO) - B8-124 (NTO)	Always	Below 1 Ω
   B16-2 (NTB) - B8-123 (NTB)	Always	Below 1 Ω
   B8-123 (NTB) - Body ground	Always	10 kΩ or higher
   B8-124 (NTO) - Body ground	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

NEXT: Go to next step
