STEP 8. Check TP sensor connector B-07 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 9.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

P.00E-2

.

STEP 9. Check the resistance of the ground circuit at TP
sensor connector B-07.
(1) Disconnect TP sensor connector B-07 and measure at the

harness side.

(2) Check the resistance between terminal 1 and ground.

• The resistance should measure less than 2 ohms.

Q: Is the resistance less than 2 ohms?

YES : Go to Step 12.
NO : Go to Step 10.

STEP 10. Check PCM connector C-54 <2.4L Engine> or
C-55 <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 11.
NO : Repair or replace the damaged components. Refer to

GROUP 00E, Harness Connector Inspection

STEP 11. Check the harness for an open circuit or damage
between TP sensor connector B-07 terminal 1 and PCM
connector C-54 <2.4L Engine> or C-55 <3.0L Engine>
terminal 57.
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO : Repair or replace the harness wire.

STEP 12. Measure 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 the "ON" position.

(3) Measure the voltage between terminal 46 and ground by

backprobing.

• The voltage should measure between 4.9 and 5.1 volts.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage between 4.9 and 5.1 volts?

YES : Go to Step 15.
NO : Go to Step 13.

STEP 15. Check the TP sensor.
(1) Disconnect connector B-07 and measure at the TP sensor

side.

(2) Measure the resistance between TP sensor connector

terminal 1 and 4.

Standard value: 3.5

− 6.5 kΩ

(3) Measure the resistance between TP sensor connector

terminals 1 and 3.

(4) Move the throttle valve from the idle position to the full-open

position.

• The resistance should change smoothly in proportion to

the opening angle of the throttle valve.

Q: Does the resistance change smoothly between 3.5

− 6.5

k

Ω in proportion to the opening angle of the throttle

valve?
YES : Go to Step 16.
NO : Replace the TP sensor. Refer to GROUP 13A <2.4L

Engine>, Throttle Body Assembly

.

STEP 16. Check PCM connectors C-54 <2.4L Engine> or
C-55 <3.0L Engine> and C-57 <2.4L Engine> or C-59 <3.0L
Engine> for loose, corroded or damaged terminals, or
terminals pushed back in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 17.
NO : Repair or replace the damaged components. Refer to
