True Tech Ignition TH190T Throttle Position Sensor

The True Tech Ignition TH190T Throttle Position Sensor is a precision-engineered sensor designed to monitor throttle valve position and transmit accurate voltage signals to your vehicle's computer. This sensor plays a critical role in engine management by detecting the opening and closing speed of the throttle valve, enabling the ECU to optimize idle control, fuel enrichment, and fuel cut-off for maximum efficiency and performance.

Key Features:

• Advanced sliding contact technology with multiple precious metal contacts on polymer thick film resistors for extended service life
• Integral rotor bearings and return springs for easy installation and proper voltage output
• Female plug-in connector with 3 male blade terminals for reliable electrical connections
• Includes O-ring seal for proper fitment and protection
• Rigorous end-of-line testing validates output voltages and linearity specifications
• Maintains OE-specific installed outputs rather than using adjustable consolidated designs

The TH190T is manufactured by Standard Motor Products under their True Tech Ignition brand, providing quality replacement parts at competitive prices. This sensor cross-references to OEM part numbers including 4882219, 4882219AB, 56027940, 89054591, and 89054615, among others. When your throttle position sensor fails, symptoms may include poor acceleration, rough idle, erratic engine behavior, and diagnostic trouble codes such as P0120, P0121, P0122, P0123, and P0221.
