Overview
The ZF 0501.335.219 SENSOR is a critical electronic monitoring component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part directly interfaces with the transmission’s Control Unit & Electronics to relay real-time rotational speed and position data to the TCU. Mounted internally within the valve body or housing assembly, the sensor ensures precise shift timing and clutch modulation. The SKU 0501.335.219 is factory-calibrated for plug-and-play replacement, restoring factory-level communication between the mechanical drivetrain and the electronic control system. When paired with a functioning 4699001185: GK10LD, this sensor forms the backbone of the transmission’s feedback loop.
Symptoms of Failure
- Erratic or delayed gear engagement: A failing sensor sends intermittent signals, causing the TCU to hesitate or skip gears during acceleration.
- Transmission limp mode activation: The control unit detects missing or implausible sensor data and forces the gearbox into a safe, reduced-power mode.
- Harsh or flared shifts: Without accurate input speed data, clutch application becomes abrupt or slips, leading to noticeable jerking.
- Intermittent speedometer or tachometer fluctuation: The sensor’s output directly affects dashboard readings, causing needle bouncing or zero readings.

Compatibility
This sensor is specifically designed for the ZF WG100, WG130, and WG131 series transmissions commonly found in medium-duty trucks, construction loaders, and agricultural tractors. It is also compatible with select variants of the WG180 and WG200 series where the Control Unit & Electronics architecture matches the 0501.335.219 pinout. Always verify the sensor port location on the 4699101108: HOUSING before installation. For complete driveline restoration, inspect the 4699102172: INPUT shaft and 4699103057: OUTPUT shaft for wear, as sensor failure often coincides with mechanical degradation in these areas.
