CHECKING AND ADJUSTING THE
THROTTLE POSITION SENSOR
Before adjusting the throttle position sensor, the
engine idling speed should be properly ad-
justed.
1. Check:
S throttle position sensor
(installed on the throttle body)
a. Disconnect the throttle position sensor cou-
pler from the throttle position sensor.
b. Connect the pocket tester (Ω 1k) to the
throttle position sensor.

c. Measure the maximum throttle position sen-
sor resistance.
Out of specification ! Replace the throttle
position sensor.

(blue – black)
d. Connect the pocket tester (Ω 1k) to the
throttle position sensor.

e. While slowly opening the throttle, check that
the throttle position sensor resistance is with-
in the specified range.
Check mainly that the resistance changes grad-
ually when turning the throttle, since the read-
ings (from closed to wide-open throttle) may dif-
fer slightly from those specified.
Out of specification or the resistance
changes abruptly ! Go to step 2 below.
