The Bosch LSU 4.2 Wideband Lambda sensor supports closed-loop O2 management, ensuring optimal fuel delivery by transmitting accurate real-time engine air-fuel ratio measurements to the ECU, thereby determining the lambda value.
Fuel Compatibility: The Bosch LSU 4.2 WB-O2 sensor is compatible with unleaded gasoline, gasoline-ethanol blends, methanol, and diesel. However, the sensor's lifespan is significantly reduced if used with leaded fuel, diesel, or in 2-stroke engines.
Thread Size:The Bosch LSU 4.2 sensor has an M18 x 1.5 thread.
Product Code: 0 258 007 057 (VW Part No: 021-906-262-B)
Additional Information: Remember to handle wideband Lambda sensors with care and never disconnect the sensor plug while in operation. For specific applications or questions, please contact our technical support or sales department.
Installation and Calibration: For the sensor to function correctly, it must be paired with a wideband O2 signal conditioner (also known as a wideband O2 controller). When paired with a FuelTech wideband Lambda sensor controller, the sensor is calibrated automatically.
