Install the TPS to the throttle body as shown by (1) in
the illustration.

2.

Turn the TPS so that it is at the position shown by (2)
in the illustration, and then tighten the screw.

3.

Connect a multimeter between terminal (4) (TPS power
supply) and terminal (3) (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.

If there is an abnormality, replace the TPS.
