Non-Contact Throttle Position Sensors Solve Common Wear, Performance Issues

Hall Effect integrated circuitry eliminates hesitation, premature wear experienced with contact-type sensors.

Airtex Engine Management has introduced a line of advanced non-contact-design throttle position sensors that eliminate the premature wear and common drivability issues experienced with conventional sensor technology on many automotive models.
The new Airtex throttle position sensors are now available for an array of mid-1980s through 2007 Dodge, Ford, General Motors and Mazda applications.
Conventional original equipment and replacement throttle position sensors feature metal contact “fingers” that sweep across a printed resistor board. Repetitive motion and vehicle vibration can cause these fingers to wear holes in the board, causing engine hesitation and other potential drivability issues.
The new Airtex sensors utilize advanced Hall Effect integrated circuitry that eliminates wear-intensive contact with the circuit board. This technology until now has not been widely available in the aftermarket, in spite of its significant advantages over conventional throttle position sensor designs.
“It’s rare that a manufacturer would upgrade its technology across such a wide range of applications and model years, but our non-contact-design sensors help Airtex customers provide a higher quality, longer lasting repair,” said Glen Eichhorn, vice president, electronics, Airtex Engine Management.
