STEP 2. Measure the power supply voltage at input shaft
speed sensor connector B-16.
(1) Disconnect connector B-16 and measure at the harness
side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 3 and ground.
• The voltage should measure battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?
YES : Go to Step 5.
NO : Go to Step 3.
STEP 3. Check intermediate connector C-30 and junction
block connector D-13 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 4.
NO : Repair or replace the damaged components. Refer to
GROUP 00E, Harness Connector Inspection

STEP 4. Check the harness for open circuit or short circuit
to ground between input shaft speed sensor connector
B-16 terminal 3 and the junction block connector D-13
terminal 11.
Q: Is the harness wire in good condition?
YES : Go to Step 5.
NO : Repair or replace the harness wire.
STEP 5. Measure the PCM to speed sensor output voltage
at the input shaft speed sensor connector B-16.
(1) Disconnect connector B-16 from the speed sensor and
measure voltage 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 PCM output voltage to the speed
sensor at the PCM connector C-92 by backprobing.
(1) Do not disconnect connector C-92.
(2) Disconnect connector B-16 at the input shaft speed sensor.
(3) Turn the ignition switch to the "ON" position.
(4) Measure the voltage between PCM terminal 103 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.
