STEP 1. Check harness connector B-06 at throttle actuator
control motor for damage.
Q: Is the harness connector in good condition?
YES : Go to Step 2.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 8.
STEP 2. Check the throttle actuator control motor.
(1) Disconnect the connector B-06.
(2) Measure the resistance between throttle actuator control
motor side connector terminal No. 1 and No. 4.
Standard value: 1.5
± 0.3 ohms [at 20°C (68°F)]
Q: Is the measured resistance between standard value?
YES : Go to Step 3.
NO : Replace the throttle body assembly. Then go to Step

STEP 3. Check harness connector B-20 at ENGINE-ECU for
damage
Q: Is the harness connector in good condition?
YES : Go to Step 4.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 8.
STEP 4. Check the continuity at ENGINE-ECU harness side
connector B-21.
(1) Disconnect the connector B-21 and measure at the harness
side.
(2) Measure the continuity between terminals No. 4 and ground
,No. 6 and ground.
• Should be less than 2 ohms.
Q: Does continuity exist?
YES : Go to Step 5.
NO : Repair harness wire between ENGINE-ECU
connector B-21 (terminals No. 04, No. 06) and ground
because of open circuit or harness damage. Then go
to Step 8.

(terminal No. 1) and ENGINE-ECU connector B-20 (terminal
No. 49).
Q: Is the harness wire in good condition?
YES : Go to Step 7.
NO : Repair it. Then go to Step 8.
