The Mercury Throttle Position Sensors (TPS) play a crucial role in the proper functioning of your vehicle's fuel system. They measure the position of the throttle butterfly valve and transmit this information to the engine control module, which uses it to control fuel injection, ignition timing, and other engine functions. Mercury TPS are designed to meet or exceed OEM specifications for accuracy and durability, ensuring reliable performance in all driving conditions. The high-quality construction of these sensors makes them an ideal replacement for a worn or damaged TPS. Upgrade your vehicle's fuel system with a genuine Mercury part for optimal performance and smooth operation.
