STEP 11. Measure the ground circuit for resistance at 
output shaft speed sensor connector B-15.

(1) Disconnect connector B-15 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.
