>>A<< THROTTLE POSITION SENSOR (TPS) 
INSTALLATION
1. Install the throttle position sensor to the throttle body as 

shown in the illustration.

2. Turn the throttle position sensor 90 degrees 

counterclockwise to set it, and tighten the screws.

3. Connect an ohmmeter between terminals 1 (ground) and 3 

(output), or between terminals 3 (output) and 4 (power).
Then, make sure that the resistance changes smoothly 
when the throttle valve is slowly moved to the fully open 
position.
