35102-38610 TPS4146 TPS Throttle Potentiometer Sensor for Hyundai Santa Fe (SM) 2.4 16V Trajet 2.0

The 35102-38610 (also sold as WELLS TPS4146) is a throttle position sensor engineered for Hyundai Santa Fe (SM) 2.4 16V models and Hyundai Trajet 2.0 vehicles produced from January 2004 through July 2008. This TPS sensor detects the throttle opening angle and sends that signal to the engine control unit, which then adjusts fuel injection and ignition timing accordingly. 

Key Advantages
Direct OEM fit and function – the connector, mounting holes, and shaft alignment match the Hyundai factory specifications exactly. Bolt it on and plug it in—no modifications or calibration required.

High-quality components for reliability – the internal potentiometer uses a long-life conductive plastic track, tested to withstand 1 million cycles without significant wear. The housing is constructed from glass-filled PBT, resistant to underhood heat and chemicals.

Rigorous quality control – each TPS sensor is 100% inspected before shipping, not batch-sampled. Every unit passes resistance sweep tests at both room temperature and extreme conditions to confirm stable output.
