(B): 09900–25009 (Needle-point probe set)
Tester knob indication
Voltage ( )
STP sensor output voltage
ST valve is fully closed: Approx. 0.7 V ((+): Y/W –
(–): B/Br)
6) Move the throttle body upward by loosing the throttle
body mounting screws.
7) Loosen the STP sensor mounting screw using the
special tool and adjust the STP sensor until the
output voltage comes within the specified value.
