(4) Measure the voltage between PCM terminal 111 and 

ground.

• 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 PCM connector B-22 and input shaft speed 
sensor connector B-109 for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.

Q: Are the connectors in good condition?

YES : Go to Step 8.
NO :  Repair or replace the damaged components. Refer to
