Van Wezel 0 281 004 129 Lambda Sensor

The Van Wezel 0 281 004 129 Lambda Sensor is a high‑performance oxygen sensor designed to provide precise measurement of exhaust gas composition for modern internal combustion engines. Its advanced design ensures reliable operation across a wide range of temperatures and operating conditions, making it an ideal choice for both automotive enthusiasts and professional technicians.

Key Functionalities

The sensor’s core function is to detect the oxygen content in exhaust gases, delivering real‑time data to the engine control unit (ECU). This information allows the ECU to adjust fuel injection, ignition timing, and air‑fuel mixture for optimal combustion efficiency. The result is improved fuel economy, reduced emissions, and enhanced overall performance.

Precision Engineering

Built with a high‑temperature ceramic probe, the sensor can withstand temperatures up to 650 °C without degradation. Its thin-film platinum element provides rapid response times, typically under 200 milliseconds, ensuring that the ECU receives accurate data even during transient engine conditions.

Durability and Reliability

The sensor’s robust construction includes a sealed housing with corrosion‑resistant materials, protecting internal components from harsh exhaust gases and mechanical vibrations. The design also incorporates a protective shield that minimizes the impact of particulate matter, extending the sensor’s service life.

Installation Compatibility
