Overview of the Bosch 0258006503 Lambda Sensor

The Bosch 0258006503 is a high‑performance lambda (oxygen) sensor designed for use in modern internal combustion engines. It features a vehicle‑specific connector, ensuring seamless integration with the engine control unit (ECU) of compatible Opel and Vauxhall models. The sensor measures the oxygen content in exhaust gases, providing critical data that allows the ECU to adjust fuel injection and maintain optimal air‑fuel ratios.

Key Functional Characteristics

  • Four‑wire construction: Provides a direct signal to the ECU for precise control.
  • Compact 325 mm length: Fits easily in tight engine bay spaces without requiring additional adapters.
  • Black plug design: Matches standard exhaust manifolds and catalytic converter housings.
  • High‑temperature tolerance: Operates reliably at exhaust temperatures up to 600 °C, ensuring durability under heavy load conditions.
  • Rapid response time: Enables quick adjustments to fuel delivery, improving throttle response and reducing emissions.

Compatibility Matrix

The sensor is engineered for a wide range of Opel and Vauxhall vehicles. Below are representative models that the Bosch 0258006503 serves:
