STEP 15. 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 1 and PCM connector C-54 <2.4L Engine> or
C-55 <3.0L Engine> terminal 57.

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

Connector Inspection

P.00E-2

.

STEP 16. Check connector C-54 <2.4L Engine> or C-55
<3.0L Engine> at PCM for damage.
Q: Is the connector in good condition?

YES : Go to Step 6.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

.

STEP 17. Check connector B-07 at throttle position sensor
for damage.
Q: Is the connector in good condition?

YES : Go to Step 18.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 18. Check the throttle position sensor.
(1) Disconnect connector B-07 and measure at the sensor

side.

(2) Measure the resistance between 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 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 19.
NO : Replace the throttle position sensor. Refer to GROUP

13A <2.4L Engine>, Throttle Body Assembly

P.13A-

473

or 13B <3.0L Engine>, Throttle Body Assembly

P.13B-552

.

STEP 19. Check connectors C-54 <2.4L Engine> or C-55
<3.0L Engine> and C-57 <2.4L Engine> or C-59 <3.0L
Engine> at PCM for damage.
Q: Are the connectors in good condition?

YES : Go to Step 20.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 20. Check harness for short circuit to ground 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.
Q: Is the harness wire in good condition?

YES : Go to Step 21.
NO : Repair it.

STEP 21. Check the connector and the harness for short
circuit to ground between the throttle position sensor
connector and the auto-cruise control-ECU connector.

Q: Is the harness wire in good condition?

YES : Throttle position sensor adjustment. Refer to GROUP

DTC 15: A/T Fruid Tempeature Sensor System (Open Circuit)

CIRCUIT OPERATION

•

The PCM (terminal 124) applies 5 volts to the A/T
fluid temperature sensor output terminal (terminal

1).

•

Ground terminal (terminal 2) is grounded to the
PCM (terminal 57).
