in the illustration, and then tighten the screw.
3. Connect a multimeter between terminal (1) (TPS power
supply) and terminal (2) (TPS output) of the TPS
connector, and check that the resistance increases
gradually as the throttle valve is opened slowly to the
fully-open position.
4. Check the continuity between terminal (3) (idle position
switch) and terminal (4) (earth) of the TPS connector
when the throttle valve is fully closed and fully open.
