STEP 6. Check connectors B-07 at throttle position sensor
and C-57 <2.4L Engine> or C-59 <3.0L Engine> at PCM for
damage.
Q: Are the connectors in good condition?
YES : Repair it because of harness open circuit or damage
between throttle position sensor connector B-07
terminal 3 and PCM connector C-57 <2.4L Engine> or
C-59 <3.0L Engine> terminal 78.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
.
STEP 7. Check the power supply voltage at throttle
position sensor connector B-07 by backprobing.
(1) Do not disconnect connector B-07.
(2) Turn the ignition switch to "ON" position.
(3) Measure the voltage between terminal 4 and ground by
backprobing.
•
Voltage should be between 4.8 and 5.2 volts.
(4) Turn the ignition switch to "LOCK" (OFF) position.
Q: Is the voltage normal?
YES : Go to Step 12.
NO : Go to Step 8.

STEP 8. Check the power supply voltage at PCM connector
C-54 <2.4L Engine> or C-55 <3.0L Engine> by backprobing.
(1) Do not disconnect connector C-54 <2.4L Engine> or C-55
<3.0L Engine>.
(2) Turn the ignition switch to "ON" position.
(3) Measure the voltage between terminal 46 and ground by
backprobing.
•
Voltage should be between 4.8 and 5.2 volts.
(4) Turn the ignition switch to "LOCK" (OFF) position.
Q: Is the voltage normal?
YES : Go to Step 9.
NO : Go to Step 10.
STEP 9. Check connectors B-07 at throttle position sensor
and C-54 <2.4L Engine> or C-55 <3.0L Engine> at PCM for
damage.
Q: Are the connectors in good condition?
YES : Repair it because of harness open circuit or damage
between throttle position sensor connector B-07
terminal 4 and PCM connector C-54 <2.4L Engine> or
C-55 <3.0L Engine> terminal 46.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 10. Check connector B-07 at throttle position sensor
and C-54 <2.4L Engine> or C-55 <3.0L Engine> at PCM for
damage.
Q: Are the connectors in good condition?
YES : Go to Step 11.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
.
STEP 11. Check harness for short circuit to ground
between throttle position sensor connector B-07 terminal 4
and PCM connector C-54 <2.4L Engine> or C-55 <3.0L
Engine> terminal 46.
Q: Is the harness wire in good condition?
YES : Go to Step 5.
NO : Repair it.

STEP 12. Check connector B-07 at throttle position sensor
for damage.
Q: Is the connector in good condition?
YES : Go to Step 13.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
.
STEP 13. Check the throttle position sensor.
(1) Disconnect connector B-07 and measure at the sensor
side.
(2) Measure the resistance between connector terminal 1 and
4.
Standard value: 3.5 - 6.5 k
Ω
(3) Measure resistance between the throttle position sensor
side connector terminal 1 and 3.
(4) Move the throttle valve from the idle position to full-open
position.
•
Resistance should change smoothly in proportion to
opening angle of the throttle valve.
Q: Is the resistance normal?
YES : Go to Step 14.
NO : Replace the throttle position sensor. Refer to GROUP
13A <2.4L Engine>, Throttle Body Assembly
or 13B <3.0L Engine>, Throttle Body Assembly
