ZF 0501.228.286 SPEED SENSOR for WG100/WG130/WG131

Overview

The ZF 0501.228.286 SPEED SENSOR is a critical electronic component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part monitors the rotational speed of the transmission output shaft, sending precise data to the control unit to manage shift timing and torque converter lockup. Installed directly into the transmission housing, the SKU 0501.228.286 ensures accurate signal transmission for optimal drivetrain performance. When paired with the 4699101123: HOUSING and 4699301208: HOUSING, this sensor forms the backbone of the transmission’s electronic feedback loop, enabling smooth gear engagement under heavy loads.

Symptoms of Failure

When the ZF 0501.228.286 SPEED SENSOR begins to wear out, operators may notice several distinct issues. Erratic shifting or gear slipping is a primary symptom, as the control unit receives inconsistent speed data. Delayed engagement when moving from neutral to drive or reverse often occurs, especially in WG130 transmissions. Another common failure sign is a loss of cruise control functionality, since the sensor no longer provides stable output shaft readings. Finally, intermittent warning lights on the dashboard—such as a transmission fault indicator—can point to a failing sensor, often accompanied by a stored diagnostic trouble code for speed signal loss.

Technical Specifications

Compatibility

This ZF 0501.228.286 SPEED SENSOR is engineered for the WG100, WG130, and WG131 transmission families. It is also compatible with select WG180 and WG200 variants that share the same sensor mounting interface and control architecture. For proper installation, ensure the 4699301017: BEARING COVER and 4699301085: COVER are correctly aligned to prevent signal interference. Always verify your transmission’s serial number against ZF’s OEM catalog to confirm fitment before ordering.
