STEP 28. Check the transmission range switch.
Measure the resistance between the terminals for each selec-
tor position as indicated in the tables above.

Q: Does the resistance measure less than 2 ohms for each 

selector position?
YES : Go to Step 29.
NO :  Replace the transmission range switch. Refer to 

GROUP 23B, Transmission 

P.23B-18

.

STEP 29. Check transmission range switch connector C-04 
for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Is the connector in good condition?

YES : Go to Step 30.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection

STEP 30. Measure the transmission range switch output 
voltage at PCM connector D-134 by backprobing.
(1) Do not disconnect connector D-134.
(2) Turn the ignition switch to the "ON" position.
(3) Move the selector lever to the "D" position.

(4) Measure the voltage between terminal 76 and ground by 

backprobing.

• The voltage should measure battery positive voltage.

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

YES : Go to Step 13.
NO :  Go to Step 31.

STEP 31. Check PCM connector D-134 and intermediate 
connector E-114 for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 32.
NO :  Repair or replace the damaged components. Refer to
