8. Hand-tighten the two bolts that hold the TPS in place.
9. Connect the electrical connector to the TPS.
10. Start the engine and let it run for a few minutes.
11. Check the TPS voltage with a multimeter. The TPS voltage should be between 0.5 and 4.5 volts.
12. If necessary, adjust the TPS voltage by turning the adjustment screw on the TPS.
13. Once the TPS voltage is set, tighten the two bolts that hold the TPS in place.
14. Test the TPS by opening and closing the throttle. The TPS voltage should change smoothly as the throttle is opened and closed.
