Product Overview
This magnetic pickup reads flywheel or gear-tooth speed and sends engine RPM information to the governor or controller. A weak or missing signal can cause unstable speed control, fault codes or a no-run condition on some systems.
Inspect the wiring and connector before replacing the sensor. A damaged harness, corrosion or an incorrect sensor gap can create the same fault.
