STEP 21. Check the transmission range switch.
Measure the resistance between the terminals for each selec-
tor position as indicated in the table below.

NOTE: For vehicles with sport mode, four positions (P, R, N, D) 
are used.
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 

GROUP 23B, Transaxle 

P.23B-10

.

STEP 22. Check transmission range switch connector B-41 
for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 23.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection

STEP 23. Measure the transmission range switch output 
voltage at PCM connector C-61 <2.4L Engine> or C-63 
<3.0L Engine> by backprobing.
(1) Do not disconnect connector C-61 <2.4L Engine> or C-63 

<3.0L Engine>.

(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: Does the voltage measure battery positive voltage?

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

STEP 24. Check PCM connector C-61 <2.4L Engine> or 
C-63 <3.0L Engine> for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 25.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection

STEP 25. Check harness for open circuit or short circuit to 
ground between transmission range switch connector 
B-41 terminal 4 and PCM connector C-61 <2.4L Engine> or 
C-63 <3.0L Engine> terminal 121.
Q: Is the harness wire in good condition?

YES <Vehicles without sport mode> : Go to Step 5.
YES <Vehicles with sport mode> : Go to Step 26.
NO :  Repair or replace the harness wire.

STEP 26. Check intermediate connector C-27 and 
combination meter connector C-43 for loose, corroded or 
damaged terminals, or terminals pushed back in the 
connector. <Vehicles with sport mode>
Q: Are the connectors and terminals in good condition?

YES : Go to Step 27.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection
