Output speed sensor inspection (AWR6B45)

1. Engine harness inspection

1) Disconnect the engine harness from the TCM.

2) Check for continuity between each connector terminal combinations listed in the table using a DMM.

Note

  • Check that continuity is as specified in the table.
  • A resistance value of 100 kΩ or more may be detected when resistance is measured between the terminals, but this is not a malfunction.

Caution

  • Do not damage the terminals.

2. Output speed sensor inspection

1) Remove the output speed sensor from the transmission.

2) Check for continuity between each connector terminal combinations listed in the table using a DMM.

Note

  • Check that continuity is as specified in the table.
  • A resistance value of 100 kΩ or more may be detected when resistance is measured between the terminals, but this is not a malfunction.

Caution

  • Do not apply impact to the output speed sensor.
  • Do not damage the terminals.

3) Connect the battery positive terminal the SP+ terminal and the battery negative terminal to the SP- terminal via a 100 Ω resistor and ammeter.

Caution

  • Do not apply impact to the output speed sensor.
  • Do not damage the terminals.

4) Inspect the current of the steel material (non-magnetic) while brushing to the left and right with the tip of the input speed sensor (within 5 mm {0.197 in}).

Caution

  • Do not hit or damage the steel material with the input speed sensor when inspecting the current.
  • Do not damage the terminals.
