Throttle Position Sensor Adjustment - LC Engineering

2031 Holly Avenue, Lake Havasu City, AZ 86404 Office Fax Throttle Position Tech & Adjustment Procedure The Toyota 22RE and 3VZ engines are electronically fuel injected. As such they lack a mechanical carburetor and instead split the function of the carburetor into three parts, namely the air flow meter in the air cleaner box, the Throttle body and the fuel injector. The air flow meter uses a flapper vane and temperature Sensor to detect the temperature and velocity/flow of the incoming air charge. The Throttle body controls the airflow into the engine and the fuel injectors supply the proper amount of fuel to the engine depending upon operating conditions. The Throttle body contains the Throttle valve that it operated by the accelerator pedal in the driver's compartment. The valve serves to regulate the amount or air that gets introduced into the engine. The fuel injectors spray atomized fuel into the intake of each cylinder in response to an electrical signal from the engine computer (ECU).
