SENSOR INSPECTION
(1) Disconnect the throttle position sensor connector, and
connect the special tool (Test harness) between the
disconnected
(2) Measure the resistance between terminal @ (black clip of
special tool) and terminal @ (red clip) of the connector on
throttle position sensor side.
Standard value: 3.5-6.5 kS2
(3) Measure the resistance between terminal @ (black clip of
special tool) and terminal @ (blue clip).
Open the throttle valve slowly
from idle position to fully open

(4) If the resistance does not conform with specification, or
does not vary smoothly, replace the throttle position
sensor.
