STEP 21. Check the transmission range switch.

Measure the resistance between the terminals for each trans-
mission range as indicated in the table below.

Q: Is the measured resistance less than 2 ohms for each

selector position?
YES : Go to Step 22.
NO : Replace the transmission range switch. Refer to

STEP 23. Measure the transmission range switch output
voltage at PCM connector C-92 by backprobing.

(1) Do not disconnect connector C-92.
(2) Turn the ignition switch to the "ON" position.
(3) Move the selector lever to the "N" position.

(4) Measure the voltage between terminal 121 and ground by

backprobing.

• The voltage should measure battery positive voltage.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 13.
NO : Go to Step 24.
