How to remove and install the throttle body on Lexus RX330?

Begin the repairs of 2004-2007 Toyota Highlander, Lexus RX300, and Lexus RX330 vehicles by removing the air intake duct from throttle body inspection for carbon build-up; proceed with aerosol carburetor cleaner and toothbrush cleaning followed by safety checks of oxygen sensor systems and catalytic converters for the chosen cleaner. The first step requires both disconnecting the negative battery cable and removing the engine cover along with the strut brace and air intake duct. Start by clamping the coolant hoses to reduce fluid loss before disconnecting the throttle body electrical connector while releasing the electrical harness from the fuel pipe bracket clip. Before beginning uninstall the fuel hose from the bracket while also tagging and removing the throttle vacuum and coolant lines until completing the procedure. Seal all coolant lines using retainers. Detach and remove the throttle body while discarding the existing gasket by taking out the throttle body mounting bolts. The installation process follows the removal steps with a new gasket and correct torque when tightening the throttle body mounting bolts while checking for and possibly adding coolant.

Lexus RX330 Throttle Body

The Lexus RX330 Throttle Body controls the amount of air that flows into the engine to ensure that the powertrain computer mixes the fuel in a fine manner that generates power smoothly and efficiently. This Throttle Body is mounted between the air cleaner and intake manifold and has a butterfly valve pivoting in time with the accelerator input, enabling the Lexus engine control module to adjust added airflow to longer injector pulses. Early RX330 models of the Lexus crossover applied a mechanical cable connecting the pedal to the Throttle Body, but Electronic Throttle Control, which uses an electric motor in place of the cable, under the control of the PCM based on the signal of two Accelerator Pedal Position sensors, replaced the cable shortly thereafter and added traction and stability control. Whichever actuation style, every RX330 Throttle Body has a throttle position sensor and idle bypass passage to the Idle Air Control valve to allow the computer to adjust idle speed. Although it is durable and has a long mileage, high mileage may invite shaft wear and carbon accumulation in the Throttle Body; thus, cleaning it periodically or alternatively changing it depending on the brand that is being applied is a sure way of ensuring that Lexus RX330 engines can run smoothly.
