STEP 22. Check the 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 "ON" position.
(3) Move the selector lever to "N" position.

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

backprobing.

•

Voltage should be battery positive voltage.

(5) Turn the ignition switch to "LOCK" (OFF) position.

Q: Is the voltage normal?

YES : Go to Step 12.
NO : Go to Step 23.

STEP 23. Check connectors C-61 <2.4L Engine> or C-63
<3.0L Engine> at PCM for damage.
Q: Are the connectors in good condition?

YES : Go to Step 24 <Vehicles with sport mode>. Repair it

because of the harness open circuit or short circuit to
ground between the Park/Neutral position switch
connector B-41 terminal 4 and PCM connector C-61
<2.4L Engine> or C-63 <3.0L Engine> terminal 121.
<Vehicles without sport mode>

NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 24. Check harness for open circuit or short circuit to
ground between Park/Neutral position switch connector B-
41 terminal 4 and PCM connector C-63 terminal 121
<Vehicles with sport mode>.
Q: Is the harness wire in good condition?

YES : Go to Step 25.
NO : Repair it.

STEP 25. Check connectors C-27 at intermediate
connector and C-43 at combination meter for damage
<Vehicles with sport mode>.
Q: Are the connectors in good condition?

YES : Repair it because of the harness short circuit to

ground between the Park/Neutral position switch
connector B-41 terminal 4 and Combination meter C-
43 terminal 9.

NO : Repair or replace it. Refer to GROUP 00E, Harness
