  Q: How to replace and adjust the throttle position (TP) sensor on Hyundai Santa Fe?

  A: The TP sensor is located on the throttle body. To replace it, first disconnect the cable from the negative battery terminal. If necessary, remove the engine cover. Next, disconnect the TP sensor electrical connector, which has slotted mounting holes for adjustment. Mark the position of the sensor if you plan to reinstall the same one, then remove the TP sensor mounting screws and take the sensor off the throttle body. Install the new sensor and rotate it until the mounting holes align with those in the throttle body, ensuring that installation is the reverse of removal. For adjustment using a scan tool, connect it to the 16-pin Data Link Connector (DLC) and display the throttle position sensor values. Turn the ignition key to the On position and, with the throttle fully closed, check the value on the scan tool, which should be 300 to 900 millivolts for 2.4L four-cylinder and 3.5L V6 engines, and 250 to 800 millivolts for the 2.7L V6 engine from 2001 to 2006. If the sensor voltage is outside this range, loosen the mounting screws and adjust the sensor until it falls within the specified range, then securely tighten the screws. For adjustment using a voltmeter, connect the negative lead of a high-impedance digital voltmeter to a good ground and the positive lead to the TP sensor signal wire, which may require back probing the connector. The signal wire designations are Terminal 3 of the TP sensor connector for the 2.4L engine (orange wire), Terminal 3 for the 2.7L engine (red/orange wire), and Terminal 4 for the 3.5L engine (yellow wire). Follow the previous steps to check and adjust the TP sensor as necessary.
