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.
Positive tester probe → blue 1
Negative tester probe → black 2
c. Measure the throttle position sensor maxi-
mum resistance.
d. Calculate the throttle position sensor maxi-
mum resistance when the throttle is closed.
Throttle position sensor maximum
resistance (throttle is fully closed) =
Maximum resistance × (0.13 ~ 0.15)
Example:
If the maximum resistance = 5 kΩ, then the
throttle position sensor's maximum resistance
when the throttle is fully closed should be:
5 kΩ × (0.13 ~ 0.15) = 650 ~ 750 Ω
Lift the throttle body assembly slightly out of
the intake manifolds. Loosen the throttle posi-

tion sensor screws 4.
Connect the pocket tester (Ω × 100) to the
throttle position sensor.
Positive tester probe → yellow 3
Negative tester probe → black 2
e. Adjust the throttle position sensor angle so
the measured resistance is within the speci-
fied range.

After adjusting the throttle position sensor
angle, tighten the throttle position sensor
screws.
