Genuine Mazda RX-8 Throttle Position Sensor

The Mazda RX-8 Throttle Position Sensor converts each millimeter of pedal movement into an electrical signal, which the rotary engine computer interprets to produce razor-sharp power and a clean burn when firing the fuel. The sensor, mounted on the throttle shaft, samples hundreds of times a second, enabling the ECU to balance airflow, spark, and fuel such that the coupe can jump out of the lights, steam around corners, or just cruise home without a stutter. Early contact style units featured a sliding wiper on a resistive strip, which may wear and give the throttle a jerky action, whereas later Mazda systems applied a non-contact Hall-effect design that senses a magnetic field rather than friction, wiping away mechanical wear and increasing long-term reliability. Whether an early 2004 six-speed manual RX-8 or a late 2011 automatic, the Throttle Position Sensor has the same plug pattern and calibration hints, meaning that it can be easily replaced and is expected to behave exactly the same as all the other units in the production run. Its inbuilt closed throttle switch is a signal that immediately confirms proper closing of the butterfly, and a WOT that notifies fast downshifts in automatic gearboxes, integrating economy and aggressiveness. The sensor also assists the RX-8 in remaining calm on a slip road by feeding accurate information to traction control and stability logic that in turn helps to avoid sudden bursts of power to the driver and drivetrain. A small rare-earth magnet is combined with a closed circuit, protecting against dust, oil, and vibration and is a detail that has allowed this Mazda component to outlast the competition and retain clean throttle action through many miles. Famous in Mazda circles as a marriage of strength and speed in its construction, with response as fast as lightning, this Throttle Position Sensor keeps the lightweight sports coupe up to date and ready to rev, saves fuel during normal cruising, and provides an additional measure of confidence to each drive.
