The Mazda 3 Throttle Position Sensor follows the movement of the foot pedal by matching it to the accurate delivery of fuel that gives the driver immediate and predictable power each time they press the accelerator. This small element is mounted on the throttle shaft side of the intake manifold and supplies the engine computer with a continuous flow of voltage which replicates plate angle in real time, so acceleration, cruising, and deceleration do not feel jumpy. It fits all generations of the Mazda 3 and works with both the original 2004 release and the new turbo hatch, drops into existing wiring connectors, and is fully compatible with stock engine control software, i.e., it does not require special tuning. The replacement of the previous contact potentiometers with the new non-contact magnetic circuitry avoids internal friction to maintain consistency in the readings even after thousands of stop-and-go cycles on a hot summer day or cold winter day. Due to the fact that even a small rotation is registered by the Throttle Position Sensor without any rubbing components, it is usable even with high vibration and hardly goes out of calibration, a major factor behind the model gaining great reputation for reliability and long-term performance. This gives drivers a fast throttle response, consistent idle, and better fuel efficiency and enables the computer to make timely interventions such as stability control and traction systems, making them safer in wet or icy conditions. Failures will be indicated by a flashing light on the dashboard in case of problems and the drivability will be lowered, enabling prompt repair and avoiding any roadside surprises. The test drivers in the fleet testing have frequently mentioned that this Throttle Position Sensor keeps the factory spec voltage long after 150,000 miles, which helps the Mazda name remain associated with reliability. Mazda's engineering emphasis on longevity is also apparent in the design, and the car produces consistent output even when its rivals have succumbed. Be it the spirited 3 hatchback or the comfort-oriented sedan, owners are assured that the handling of the engine will be sharp mile after mile.
