Proflow's throttle position sensors are designed to bolt onto the throttle blade shaft and relay throttle opening/closing information to the system ECU. These throttle position sensors are constructed from highly conductive, plastic-resistance material with a sensitive rotator for accurate throttle position measurement.

Replacement for Proflow's quad throttle body (PFEQTB1000) and Holley Terminator 4150 throttle bodies.
