2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   1 (NTB) sensor side - A-1 (NTB) wiring harness connector side	Always	Below 1 Ω
   2 (NTO) sensor side - A-2 (NTO) wiring harness connector side	Always	Below 1 Ω
   1 (NTB) sensor side - Body ground and other terminals	Always	10 kΩ or higher
   2 (NTO) sensor side - Body ground and other terminals	Always	10 kΩ or higher

OK: Go to next step 

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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   E8-1 (NTB) - E26-116 (NTB)	Always	Below 1 Ω
   E8-2 (NTO) - E26-115 (NTO)	Always	Below 1 Ω
   E8-1 (NTB) or E26-116 (NTB) - Body ground and other terminals	Always	10 kΩ or higher
   E8-2 (NTO) or E26-115 (NTO) - Body ground and other terminals	Always	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the wiring harness connector.
2. Measure the resistance according to the value(s) in the table below.

OK: Go to next step 

Refer to COMPONENTS

NEXT: Go to next step 

1. Connect the Techstream to the DLC3.
2. Start the engine and turn the Techstream on.
3. Clear the DTCs. Refer to DTC CHECK / CLEAR .

   HINT: 

   Write down the currently output DTCs before clearing them.

4. Perform the monitor drive pattern. Refer to MONITOR DRIVE PATTERN .
5. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
6. Read the DTCs using the Techstream.

   Result

   Display (DTC Output)	Proceed to
   Only "P0715 or P0717" is output	A
   No output	B

B → END
