  Q: How to disconnect, remove, and reinstall the Throttle Position (TP) sensor on Lexus RX330 and Toyota Highlander?

  A: On 1999 through 2003 models, the TP sensor is located on the throttle body, while on 2004 and later models, the TP sensor is an integral part of the electronic throttle body and is not removable. Disconnect the cable from the negative battery terminal. If necessary, remove the engine cover. Disconnect the TP sensor electrical connector by depressing the release tab and pulling off the connector. Then, remove the two sensor mounting screws and the sensor, this process is the same for both four-cylinder and V6 engines. When removing the TP sensor from the throttle body, especially on V6 models, be aware of limited space between the TP sensor and the firewall. If it's difficult to loosen the sensor screws, consider removing the throttle body and trying again. For installation, position the TP sensor 30 to 60-degrees counterclockwise from its installed position, then rotate it clockwise until the mounting holes in the TP sensor align with those in the throttle body. Complete the installation by following the removal procedure in reverse.
