Electronic Throttle Actuator: Testing and Inspection

INSPECTION





INSPECT THROTTLE CONTROL MOTOR w/ CLUTCH
(a) Disconnect the throttle control motor w/ clutch connector.
(b) Using an ohmmeter, measure the motor resistance between terminal 1 (M+) and 2 (M-).

Motor resistance: 0.3-100 Ohms at 20°C (68°F)

If the resistance is not as specified, replace the throttle control motor w/ clutch.
(c) Using an ohmmeter, measure the clutch resistance between terminal 3 (CL-) and 4 (CL+).

Clutch resistance: 4.2-5.2 Ohms at 20°C (68°F)

If the resistance is not as specified, replace the throttle control motor w/ clutch.
(d) Reconnect the throttle control motor connector.
