How to replace and adjust the TP sensor on Hyundai Sonata?

The TP sensor is located on the throttle body and is serviceable only on models from 1999 to 2005; for 2006 and later models, it is part of the electronic throttle control module. To replace the sensor, first disconnect the cable from the negative battery terminal, then remove the engine cover if necessary. Disconnect the TP sensor electrical connector, mark the position of the sensor if planning to reinstall the same one, and remove the mounting screws to take the sensor off the throttle body. Install the new or reinstalled sensor by aligning the mounting holes and tightening the screws securely. For adjustment, use a high-impedance digital voltmeter to back probe terminals 1 and 3 of the TP sensor electrical connector, ensuring the ignition key is in the on position. With the throttle fully closed, the voltmeter should read between 300 to 900 millivolts, and as the throttle opens, the voltage should increase evenly to about 4.5 volts. If the voltage is outside this range, adjust the sensor by loosening the mounting screws and turning it until the correct voltage is achieved. For V6 engines from 2005 and earlier, unplug the electrical connector, insert a 0.025-inch feeler gauge between the throttle lever and its stop, and connect an ohmmeter between terminals 1 and 2 of the TP sensor. Adjust the sensor until continuity is registered, then reconnect the electrical connector. Finally, check the sensor output voltage with the voltmeter; it should be between 250 to 800 millivolts, and if not, repeat the adjustment procedure or consider that the TP sensor may be faulty.
