DTC SET CONDITIONS (Entry Conditions and 
Malfunction Thresholds)

Check Conditions, Judgement Criteria

• Transmission range switch: multiple signal. (30 

seconds)

.

OBD-II DRIVE CYCLE PATTERN
Start the engine, keep the vehicle stopped in "P," "R," 
"N," "D," "3," "2" and "L" ranges respectively for more 
than one minute, and turn OFF the ignition switch. 
Then restart the engine, and stop the vehicle in "P," 
"R," "N," "D," "3," "2" and "L" ranges respectively for 
more than one minute.

.

TROUBLESHOOTING HINTS (The most likely 
causes for this code to be set are:)

• Malfunction of the transmission range switch

• Malfunction of the ignition switch

• Damaged harness or connector

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 

P.23B-10

.

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 

P.00E-2

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 

P.00E-2

.

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 

GROUP 00E, Harness Connector Inspection
