STEP 15. Check connectors B-05 at throttle position
sensor and C-40 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-05
terminal 1 and PCM connector C-40 terminal 57.

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

Connector Inspection

P.00E-2

.

STEP 16. Check connector C-40 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

P.00E-2

.

STEP 17. Check connector B-05 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-05 and measure at the sensor

side.

(2) Measure the resistance between terminal 1 and 4.

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

.

STEP 19. Check connectors C-40, C-41 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-05
terminal 3 and PCM connector C-41 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 Fluid 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).
