STEP 10. Check the harness for short circuit to ground
between input shaft speed sensor connector C-16 terminal
2 and PCM connector D-134 terminal 64.
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
input shaft speed sensor connector C-16.
(1) Disconnect connector C-16 from the speed sensor 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.
NO : Go to Step 12.

STEP 12. Measure the resistance at PCM connector D-134
by backprobing.
(1) Do not disconnect connector D-134.
(2) Turn the ignition switch to the "ON" position.

(3) Measure the resistance between terminal 88 and ground by

backprobing.

• The resistance should measure less than 2 ohms.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured resistance less than 2 ohms?

YES : Go to Step 13.
NO : Go to Step 15.

STEP 13. Check input shaft speed sensor connector C-16,
PCM connector D-134 and intermediate connector E-114
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 14.
NO : Repair or replace the damaged components. Refer to
