REASSEMBLY SERVICE POINTS
AA THROTTLE POSITION SENSOR
(1) Position the throttle position sensor on the throttle body
along the dotted line as shown in the illustration.
(2) Rotate the throttle position sensor anticlockwise as shown
in the illustration, and then tighten the screws.
(3) Measure resistance value between terminal Nos. 1(sensor
power supply) and 2(throttle position sensor 1st-channel
Throttle posi-
output) as well as 1(sensor power supply) and 4(throttle
tion sensor
position sensor 2nd-channel output).

Normal condition
(4) If the resistance value does not change smoothly, replace
the throttle position sensor.

Open the throttle valve slowly
from the idle position to
full-open position.

Resistance value changes
smoothly in response to
throttle valve opening angle.
