Car aficionados know that luxury is built into each Lexus, and know that only top quality replacement IS300 parts will suffice when maintenance needs to be done. Anyone who owns a Lexus knows that when it comes to repairing their vehicle only the highest quality replacement parts will do. While it's not hard to find replacement parts for Lexus vehicles, these days only the highest quality are required to repair your automobile.
Constant communication between the ECU and throttle position sensor is required to maintain an ideal balance between fuel efficiency and power output. The throttle position sensor on your Lexus IS300 monitors the movement of the butterfly plates inside the throttle body and reports this to the ECU. It may lower the amount of fuel being sent to the injectors, or it may downshift the transmission and give you a boost of power. No matter what, your engine's performance really depends on the Lexus IS300 throttle position sensor.
