DTC P0720, P0722; Output Speed Sensor Circuit [08/2013 - 08/2016]: 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 / Primary.
5. In accordance with the display on the Techstream, read the Data List.

   Powertrain > Engine and ECT > Data List

   *1	Battery	*2	Ammeter
   *a	Component without harness connected (Transmission Revolution Sensor (NOUT))	*b	Magnet
   *c	5 mm or less	-	-

3. Wave a magnetic object left and right in front of the transmission revolution sensor (NOUT) tip (5 mm (0.197 in.) or less) to change the high/low signals while measuring the current.
   NOTE:

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

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

   Standard Current

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

REPLACE TRANSMISSION REVOLUTION SENSOR (NOUT). Refer to  COMPONENTS [08/2013 - ] 

Result:  1

OK 

See step  3

1. Disconnect the B31 transmission revolution sensor (NOUT) connector.
2. Disconnect the B33 ECM connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   B31-1 (NOTO) - B33-129 (NOTO)	Always	Below 1 Ω
   B31-2 (NOTB) - B33-130 (NOTB)	Always	Below 1 Ω
   B31-1 (NOTO) or B33-129 (NOTO) - Body ground and other terminals	Always	10 kΩ or higher
   B31-2 (NOTB) or B33-130 (NOTB) - Body ground and other terminals	Always	10 kΩ or higher

4. Connect the B33 ECM connector.
5. Connect the B31 transmission revolution sensor (NOUT) connector.
