 DTC detection condition

 Possible causes
P2765 INPUT SPEED SENSOR B (Input/Turbine Speed Sensor B Circuit) The secondary speed sensor value is less than 150 rpm continuously for 5 seconds or more under the following diagnosis conditions:

Diagnosis conditions

  • Primary pulley speed: 1,000 rpm or more
  • TCM power supply voltage: More than 11 V
  • Harness or connector (Secondary speed sensor circuit is open or shorted)
  • Secondary speed sensor
The secondary pulley speed sensor value is 240 rpm or less continuously for 500 msec or more under the following diagnosis conditions:

Diagnosis condition

  • 10-msec-ago secondary pulley speed: 1,000 rpm or more
  • TCM power supply voltage: More than 11 V

DTC CONFIRMATION PROCEDURE

CAUTION:

Be careful of the driving speed.

1.PREPARATION BEFORE WORK

If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.CHECK DTC DETECTION

  1. Start the engine
  2. Drive the vehicle
  3. Maintain the following conditions for 10 seconds or more.

Selector lever : “D” position

Vehicle speed : 55 km/h (34 MPH) or more

  1. Stop the vehicle.
  2. Check the first trip DTC.

Is “P2765” detected? YES >> Go to TM-223, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK SECONDARY SPEED SENSOR POWER CIRCUIT

  1. Turn ignition switch OFF.
  2. Disconnect secondary speed sensor connector.
  3. Turn ignition switch ON.
  4. Check voltage between secondary speed sensor harness connector terminal and ground.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 2.

NO >> GO TO 6.

2.CHECK SECONDARY SPEED SENSOR GROUND CIRCUIT

Check continuity between of secondary speed sensor harness connector terminal and ground.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 3.

NO >> Repair or replace malfunctioning parts.

3.CHECK CIRCUIT BETWEEN SECONDARY SPEED SENSOR AND TCM (PART 1)

  1. Turn ignition switch OFF.
  2. Disconnect TCM connector.
  3. Check continuity between secondary speed sensor harness connector terminal and TCM harness connector terminal.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 4.

NO >> Repair or replace malfunctioning parts.

4.CHECK CIRCUIT BETWEEN SECONDARY SPEED SENSOR AND TCM (PART 2)

Check continuity between secondary speed sensor harness connector terminal and ground.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace malfunctioning parts.

5.Check TCM Input signals

  1. Connect all of disconnected connectors.
  2. Lift the vehicle.
  3. Start the engine.
  4. Check frequency of secondary speed sensor.

Is the inspection result normal?


Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".

NO >> Replace secondary speed sensor. TM-269, "Removal and Installation".
