Walker 200-1003 Throttle Position Sensor

Walker 200-1003 Throttle Position Sensor

Walker Products 200-1003 is a throttle position sensor for throttle body mounted applications that require a 3-wire, oblong female connector design. Built with a plastic housing and an adjustable configuration, it supports accurate throttle signal feedback for older fuel-injected vehicles that depend on consistent sensor input.

Walker Products has supplied fuel system and engine management components since 1946, with manufacturing and engineering support focused on meeting or exceeding OEM standards. The Walker Products line includes throttle position sensors, cam and crankshaft sensors, oxygen sensors, fuel injectors, and related engine management parts for aftermarket repair.
