STEP 6. Measure the PCM output voltage to the speed
sensor at PCM connector C-92 by backprobing.

(1) Do not disconnect connector C-92.
(2) Disconnect connector B-15 at the output shaft speed

sensor.

(3) Turn the ignition switch to the "ON" position.

(4) Measure the voltage between PCM terminal 104 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.
