STEP 1. 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 2.
NO : Replace the transmission range switch. Refer to
GROUP 23B, Transaxle
STEP 2. 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 3.
NO : Repair or replace the damaged components. Refer to
GROUP 00E, Harness Connector Inspection

STEP 3. 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 4.
NO : Repair or replace the damaged components. Refer to
GROUP 00E, Harness Connector Inspection
STEP 4. Measure the transmission range switch output
voltage at PCM connector C-61 <2.4L Engine> or C-63
<3.0L Engine> by backprobing. ("P" position)
(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) Measure the voltage between terminal 101 and ground by
backprobing.
• When selector lever position is "P," voltage should mea-
sure battery positive voltage.
• When selector lever position is "R," voltage should mea-
sure 0.5 volt or less.
• When selector lever position is "N," voltage should mea-
sure 0.5 volt or less.
• When selector lever position is "D," voltage should mea-
sure 0.5 volt or less.
• When selector lever position is "3," voltage should mea-
sure 0.5 volt or less. <Vehicles without sport mode>
• When selector lever position is "2," voltage should mea-
sure 0.5 volt or less. <Vehicles without sport mode>
• When selector lever position is "L," voltage should mea-
sure 0.5 volt or less. <Vehicles without sport mode>
• When selector lever position is sport mode, voltage
should measure 0.5 volt or less. <Vehicles with sport
mode>
Q: Is the measured voltage within the specified range?
YES : Go to Step 8.
NO : Turn the ignition switch to the "LOCK" (OFF) position.
Then go to Step 5.

STEP 5. Check harness for open circuit or short circuit to
ground between transmission range switch connector
B-41 terminal 3 and PCM connector C-61 <2.4L Engine> or
C-63 <3.0L Engine> terminal 101.
Q: Is the harness wire in good condition?
YES <Vehicles without sport mode> : Go to Step 27.
YES <Vehicles with sport mode> : Go to Step 6.
NO : Repair or replace the harness wire.
STEP 6. 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 7.
NO : Repair or replace the damaged components. Refer to
