WELLS474 22620-6P005 22620-5E400 Throttle Position Sensor for Infiniti Q45 4.1L Nissan Altima GLE GX SE XE

The Throttle Position Sensor (TPS) WELLS474 / 22620-6P005 / 22620-5E400 is an important engine management component designed to monitor throttle valve movement and provide accurate position feedback to the vehicle’s electronic control unit (ECU). The throttle position sensor plays a key role in the engine control system by connecting the driver’s throttle input with ECU calculations. As the accelerator pedal position changes, the throttle valve opens or closes accordingly. The TPS continuously measures this movement and sends real-time data to the ECU.
