SENSOR INSPECTION
(1) Disconnect the throttle position sensor connector.
(2) Measure resistance between terminal @ (sensor ground)
and terminal @ (sensor power).
Standard value: 3.5-6.5 kR
(3) Connect a pointer type ohmmeter between terminal @
(sensor ground) and terminal @ (sensor .output).
(4) Operate the throttle valve slowly from the idle position to
the full open position and check that the resistance
changes smoothly in proportion with the throttle valve
opening angle.
(5) If the resistance is out of specification, or fails to change
smoothly, replace the throttle position sensor.
