MAN TGX/TGS ESP Yaw Rate Sensor Knorr-Bremse 81259370051 K020568N04 12V

Description:
This listing is for a genuine Knorr-Bremse ESP yaw rate sensor 12V used on MAN TGX and TGS heavy commercial vehicles. The sensor is part of the electronic stability programme (ESP) / braking system and measures yaw and lateral movement so that the EBS/ESP control unit can intervene to keep the truck stable. It is chassis-mounted and connects via a 4‑pin electrical connector.

OEM references on the label confirm the part as MAN 81.25937.0051 / 81259370051 with Knorr-Bremse number K020568N04 (also cross-referenced in Knorr-Bremse EBS catalogues with Bosch 0 273 014 007). The housing carries Knorr-Bremse and Bendix branding and is marked "ESP Sensor 12V" and "Made in Hungary", matching catalogue data for the MAN TGX/TGS yaw rate sensor.

The sensor is suitable for a wide range of MAN TGX and TGS Euro 5 and Euro 6 trucks where this part number is specified. Buyers should always confirm compatibility by matching the MAN or Knorr-Bremse part numbers from their original unit (81.25937-0051, 81259370051, K020568N04, K020568N50, 0 273 014 007) and consulting a MAN parts catalogue or dealer.

This item was carefully removed from a fully operational truck and the ESP system was checked for fault codes before dismantling to verify the sensor was working correctly. The unit has been visually inspected: the plastic body is intact with no cracks, the brass threaded mounting inserts are in good condition, and the 4‑pin connector shows no corrosion or damage. The original identification label is present but shows some edge wear and dirt from service. It has been lightly cleaned and is ready to install.

Professional installation is recommended. The sensor must be mounted in the correct orientation as indicated by the "DRIVING DIRECTION" arrows on the label and using proper torque on the mounting bolts. Depending on the vehicle and workshop procedures, ESP/ABS control units may require calibration or adaptation via diagnostic equipment after replacement.

This is an ideal replacement part for repairing ESP/ABS warning issues related to a failed yaw rate sensor on MAN TGX/TGS trucks, offering a cost-effective genuine alternative to a new unit. Supplied exactly as shown in the photos – sensor module only, without bolts or wiring.
