A-Premium Throttle Position Sensor TPS for Infiniti & Nissan 3.3L (1996–2004) — Direct-Fit, 6-Terminal

The A-Premium Throttle Position Sensor is a direct-fit replacement TPS engineered to match OE specifications for Infiniti QX4 (1997–2000) and Nissan 3.3L models, restoring throttle signal accuracy and drivability.

When the throttle position sensor begins to fail, your engine control unit can receive inaccurate throttle-angle readings that affect idle, acceleration responsiveness, and fuel management. A-Premium's TPS is built from durable materials and tested to meet original-equipment tolerances so you can swap it in without modifying the wiring or mounting.
