STEP 6. Measure the PCM output voltage to the speed
sensor at the PCM connector D-134 by backprobing.
(1) Do not disconnect connector D-134.
(2) Disconnect connector C-16 at the input shaft speed sensor.
(3) Turn the ignition switch to the "ON" position.

(4) Measure the voltage between PCM terminal 64 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.
NO : Go to Step 9.
