STEP 7. Check connector B-05 at throttle position sensor
for damage.
Q: Is the connector in good condition?
YES : Go to Step 8.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
.
STEP 8. Check the continuity at throttle position sensor
connector B-05.
(1) Disconnect connector B-05 and measure at the harness
side.
(2) Check for the continuity between terminal 1 and ground.
•
Should be less than 2 ohm.
Q: Is the continuity normal?
YES : Go to Step 11.
NO : Go to Step 9.
STEP 9. Check connector C-40 at PCM for damage.
Q: Is the connector in good condition?
YES : Go to Step 10.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection

STEP 10. Check harness for open circuit or damage
between throttle position sensor connector B-05 terminal 1
and PCM connector C-40 terminal 57.
Q: Is the harness wire in good condition?
YES : Go to Step 5.
NO : Repair it.
STEP 11. Check the power supply voltage at PCM
connector C-40 by backprobing.
(1) Do not disconnect connector C-40.
(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 14.
NO : Go to Step 12.

STEP 14. Check the throttle position sensor.
(1) Disconnect connector B-05 and measure at the sensor
side.
(2) Measure the resistance between connector terminal 1 and
4.
Standard value: 3.5

Ω
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 15.
NO : Replace the throttle position sensor. Refer to GROUP
13A <2.4L Engine>, Throttle Body Assembly
or 13B <3.0L Engine>, Throttle Body Assembly
STEP 15. Check connectors C-40, C-41 at PCM for damage.
Q: Are the connectors in good condition?
YES : Go to Step 16.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
