Overview
The ZF 0501.335.218 SENSOR is a critical electronic component designed for precise rotational speed and position monitoring within the WG100, WG130, and WG131 transmission series. This OEM genuine part mounts directly to the control unit housing, where it interfaces with the transmission’s internal geartrain to relay real-time data to the electronic control system. As an integral element of the Control Unit & Electronics category, the SKU 0501.335.218 ensures accurate shift timing and clutch modulation. For optimal assembly integrity, this sensor works in tandem with the 4699001185: GK10LD gasket kit, which seals the sensor bore against contamination.
Symptoms of Failure
- Erratic gear engagement or delayed shifting: A failing sensor sends intermittent signals, causing the transmission to hunt for gears or hesitate during acceleration.
- Intermittent loss of speedometer or tachometer readings: When the sensor degrades, the control unit loses input, leading to blank or fluctuating dashboard displays.
- Transmission enters limp-home mode: The system detects abnormal sensor output and defaults to a reduced-power state to prevent internal damage.
- Unusual whining or grinding noises from the valve body area: Faulty sensor data can cause incorrect clutch pressure, resulting in mechanical stress and audible wear.

Compatibility
This sensor is engineered specifically for ZF WG-series powershift transmissions, including the WG100, WG130, and WG131 models. It is also compatible with the WG180 and WG200 series when used with the appropriate 4699101108: HOUSING adapter. For complete driveline integration, the sensor communicates with the 4699102172: INPUT shaft module and the 4699103057: OUTPUT speed ring. Always verify your transmission’s control unit revision before installation.
