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

STEP 10. Check harness for short circuit to ground
between front propeller shaft speed sensor connector C-13
terminal 2 and transfer-ECU connector E-109 terminal 7.
Q: Is the harness wire in good condition?

YES : Go to Step 11.
NO : Repair or replace the harness wire.

STEP 11. Measure the ground circuit for resistance at the
front propeller shaft speed sensor connector C-13.
(1) Disconnect connector C-13 and measure at the harness

side.

(2) Measure the resistance between terminal 1 and ground.

• The resistance should measure less than 2 ohms.

Q: Is the measured resistance less than 2 ohms?

YES : Go to Step 16.
