  Q: How do you replace and adjust the Throttle Position (TP) sensor on Kia Sorento?

  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, noting that the Throttle Position sensor has slotted mounting holes for adjustment. Mark the position of the sensor if planning 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, completing the installation in reverse order of removal. For adjustment, connect a scan tool to the 16-pin Data Link Connector and bring up the Throttle Position sensor values parameter on the screen. 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 3.5L V6 engines. 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. Alternatively, using a high-impedance digital voltmeter, connect the negative lead to a good ground and the positive lead to the TP sensor signal wire, which may require back probing the sensor's connector. For the 2006 and earlier 3.5L V6 engine, the signal wire is Terminal 4 of the TP sensor connector (yellow wire). Follow the previous steps to check and adjust the TP sensor as necessary.
