SENSOR INSPECTION
(1) Disconnect the throttle position
(2) Measure resistance between terminal
and terminal 0 (sensor power).
Standard value: 3.5-6.5 kQ
(3) Connect a pointer
(sensor
terminal).
(4) Operate the throttle valve slowly from the
the full open position and check that the resistance
changes smoothly in proportion with the throttle valve
opening angle.
