POSSIBLE CAUSE

Harness or connector (Output speed sensor circuit is open or shorted)
Output speed sensor

FAIL-SAFE

Start is slow
Acceleration is slow
Lock-up is not performed

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

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

Selector lever : “D” position
Engine speed : 1,200 rpm or more
Vehicle speed : 55 km/h (34 MPH) or more

Stop the vehicle.
Check the first trip DTC.

Is “P2765” detected? YES >> Go to TM-168, "Diagnosis Procedure".

NO-1 >> To check malfunction symptom before repair: Refer to GI-41, "Intermittent Incident".

NO-2 >> Confirmation after repair: INSPECTION END

Diagnosis Procedure

1.CHECK OUTPUT SPEED SENSOR POWER CIRCUIT

Turn ignition switch OFF.
Disconnect output speed sensor connector.
Turn ignition switch ON.
Check voltage between output speed sensor harness connector terminal and ground.

Check output speed sensor power circuit

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

NO >> GO TO 6.

2.CHECK OUTPUT SPEED SENSOR GROUND CIRCUIT

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

Check output speed sensor ground circuit

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

NO >> Repair or replace malfunctioning parts.

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

Turn ignition switch OFF.
Disconnect TCM connector.
Check continuity between output speed sensor harness connector terminal and TCM harness connector terminal.

Check circuit between output speed sensor and TCM (part 1)

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

NO >> Repair or replace malfunctioning parts.

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

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

Check circuit between output speed sensor and TCM (part 2)

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

NO >> Repair or replace malfunctioning parts.

5.CHECK TCM INPUT SIGNALS

Connect all of disconnected connectors.
Lift the vehicle.
Start the engine.
Check frequency of output speed sensor.

Check TCM input signals

Is the inspection result normal? YES >> INSPECTION END

NO >> Replace output speed sensor. Refer to TM-209, "Removal and Installation".

6.CHECK CIRCUIT BETWEEN IPDM E/R AND OUTPUT SPEED SENSOR

Turn ignition switch OFF.
Disconnect IPDM E/R connector.
Check continuity between IPDM E/R harness connector terminal and output speed sensor harness connector terminals.

Check circuit between IPDM E/R and output speed sensor

Is the check result normal? YES >> GO TO 7.

NO >> Repair or replace malfunctioning parts.

7.DETECT MALFUNCTIONING ITEMS

Check the following items:

Open circuit or short circuit in harness between ignition switch and IPDM E/R. Refer to PG-15, "Wiring Diagram — Ignition Power Supply —".
Short circuit in harness between IPDM E/R harness connector terminal 70 and output speed sensor harness connector terminal 3.
10A fuse (No.46, located in the IPDM E/R). Refer to PG-68, "IPDM E/R Terminal Arrangement".
IPDM E/R

Is the check result normal? YES >> INSPECTION END

NO >> Repair or replace malfunctioning parts.
