Standard Ignition TH446 throttle position sensor for the 2010-2015 Mazda 3 4-cylinder 2.5L and other vehicles monitors the position of the throttle body valve.
A failing throttle position sensor can show up as an uneven idle, hesitation when you accelerate or a check engine light, though each of these can have other causes. Before you replace the sensor, rule out a loose or damaged connector, a dirty throttle body and other faults that produce similar symptoms. The engine takes one sensor for its throttle body.
The vehicles it fits include the 2010-2015 Mazda 3 4-cylinder 2.5L, the 2009-2014 Mazda 6 4-cylinder 2.5L and the 2012-2013 Mazda 5 4-cylinder 2.5L, and this sensor is a direct-fit replacement for each of them. It is made specifically for Mazda. Driving a different Mazda year or engine? Look up your car in the "Vehicles it fits" section.
