2-Pin Motorcycle / Automotive Rotation Sensor Waterproof Connector – OEM CY000228-2.3F

Direct OEM-specification replacement for the 2-pin waterproof wire harness connector used on rotation sensors (wheel speed sensors, crankshaft position sensors, and camshaft sensors) across motorcycle and automotive platforms. Cross-references OEM part number CY000228-2.3F. Uses the 2.3mm contact series in black nylon housing with waterproof sealing — designed for the vibration and moisture environment of engine bay and wheel hub sensor applications.

What Problem Does This Connector Solve?

Rotation sensor connectors are located in high-vibration, high-contamination zones — near the wheel hub, crankshaft, or camshaft. The 2-pin 2.3mm connector is a common failure point on high-mileage motorcycles and vehicles: the locking tab fractures under vibration fatigue, allowing moisture ingress that corrodes the terminals. A failed rotation sensor connector causes intermittent or permanent loss of the speed or position signal, triggering ABS faults, ignition timing errors, or traction control warnings. Replacing the connector is the correct first step when the sensor itself tests within specification.

Frequently Asked Questions

Q: My ABS warning light is on and the wheel speed sensor tests OK — could it be the connector?
A: Yes. A corroded or open 2-pin rotation sensor connector is a common cause of ABS faults on motorcycles. The ABS module logs a wheel speed sensor circuit fault when the signal is absent or erratic. Inspect and replace the connector before replacing the sensor.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
