Overview
The ZF 4661.124.001 TEMPERATURE SENSOR is a critical electronic component engineered specifically for the WG 94 Series transmission. This OEM genuine part monitors the thermal condition of the transmission fluid by directly measuring the oil temperature within the valve body or sump area. Accurate temperature data is essential for the transmission control unit (TCU) to regulate shift timing, torque converter lockup, and cooling system engagement. The SKU 4661.124.001 ensures precise resistance-to-temperature mapping, preventing thermal degradation of internal seals and clutches. This sensor is typically mounted near the 4661101024: TRANSMISSION HOUSING and works in conjunction with the 4661301054: HOUSING II to maintain structural integrity during thermal expansion cycles.
Symptoms of Failure
- Erratic shift timing or harsh engagement – When the sensor sends incorrect temperature signals, the TCU may delay or rush gear changes, causing jerky acceleration.
- Transmission overheating without warning – A failed 4661.124.001 can fail to trigger the cooling circuit, leading to fluid temperatures exceeding safe limits.
- Torque converter clutch slip – Inaccurate temperature readings prevent proper lockup, resulting in fuel economy loss and increased wear.
- Check engine or transmission warning light – The ECU logs temperature sensor circuit faults, often accompanied by diagnostic trouble codes (DTCs) like P0711 or P0713.

Compatibility
This temperature sensor is designed for the ZF WG 94 Series, which includes the WG94, WG180, and WG200 transmission models. It is also compatible with select ZF Ecomat 4HP and 5HP variants that share the same oil sump architecture. The sensor interfaces directly with the 0631306174: CYLINDRICAL PIN alignment feature and is secured near the 0769123894: TYPE PLATE for identification purposes. Always verify your transmission’s serial number before ordering.
