STEP 4. Check the harness for open circuit or short circuit 
to ground between front propeller shaft speed sensor 
connector C-13 terminal 3 and junction block connector 
D-212 terminal 9.
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO :  Repair or replace the harness wire.

STEP 5. Measure the sensor output voltage at front 
propeller shaft speed sensor connector C-13.
(1) Disconnect connector C-13 and measure at the harness 

side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal 2 and ground.

• The voltage should measure between 4.5 and 4.9 volts.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.5 and 4.9 volts?

YES : Go to Step 11.
NO :  Go to Step 6.

STEP 6. Measure the sensor output voltage at 
transfer-ECU connector E-109 by backprobing.
(1) Do not disconnect connector E-109.
(2) Disconnect connector C-13 at the front propeller shaft 

speed sensor.

(3) Turn the ignition switch to the "ON" position.

(4) Measure the voltage between terminal 7 and ground by 

backprobing.

• The voltage should measure between 4.5 and 4.9 volts.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.5 and 4.9 volts?

YES : Go to Step 7.
NO :  Go to Step 9.

STEP 7. Check front propeller shaft speed sensor 
connector C-13 and transfer-ECU connector E-109 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 8.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection
