STEP 10. Check the harness for short circuit to ground
between PCM connector B-22 terminal 112 and output
shaft speed sensor connector B-107 terminal 2.
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
output shaft speed sensor connector B-107.
(1) Disconnect connector B-107 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 the PCM connector
B-22 by using check harness special tool MB991923.
(1) Disconnect all the connectors from the PCM.
(2) Connect special tool MB991923 (check harness) between
the PCM and the body-side harness connector.
(3) Turn the ignition switch to the "ON" position.

(4) Measure the resistance between terminal 113 and ground.
• The resistance should measure less than 2 ohms.
(5) 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 PCM connector B-22 and output shaft
speed sensor connector B-107 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
