How do you adjust a TPS on a 97 Nissan Hardbody?

To adjust the throttle position sensor (TPS) on a 1997 Nissan Hardbody, first, locate the TPS on the throttle body. Use a multimeter to measure the voltage output by connecting it to the middle terminal of the TPS and grounding it. With the ignition on (engine off), the voltage should be around 0.5 to 0.6 volts at closed throttle. If it's not, loosen the TPS mounting screws and adjust the sensor until you reach the correct voltage, then tighten the screws securely.
