The incoming air is controlled by Lexus RX350 Throttle Body to ensure that the engine responds to each tap of the pedal. This Throttle Body, which sits between the air cleaner and the intake manifold, has a butterfly valve that opens as the accelerator moves and the sensors provide an indication to the Powertrain Control Module to deliver corresponding fuel. Early RX350 versions relied on cable linkage, but Lexus has rapidly switched to Electronic Throttle Control, where an electric motor and pedal position detectors are applied, eliminating hanging cables and allowing stability systems to share throttle decisions. In any year, an idle bypass within the Throttle Body works in conjunction with an Idle Air Control passage to maintain the revs steady and a throttle position sensor on the shaft to indicate blade angle to allow accurate calculation of the mixture. These upgrades contribute to the RX350 remaining smooth in driveability at all speeds. Carbon may accumulate on the Throttle Body plate despite its toughness when the car has traveled over high mileage, leading to rough idle, and thus it is good practice to clean the Throttle Body plate periodically. This is a relatively simple maintenance on Lexus cars and prevents the aging RX350 from stalling and keeps the current Lexus crossovers running without fear.
