How do you adjust throttle position sensor on 1997 corolla?

To adjust the throttle position sensor (TPS) on a 1997 Corolla, first, locate the TPS on the throttle body. Disconnect the electrical connector and use a multimeter to measure the voltage output while slowly opening the throttle. The voltage should typically range between 0.5 to 0.9 volts at idle and increase smoothly as the throttle opens. If adjustments are needed, loosen the mounting screws and rotate the sensor slightly until the correct voltage is achieved, then retighten the screws and reconnect the connector.
