Bosch 0 258 010 528 Oxygen Sensor Lambda Sensor - 0 258 010 528

The Bosch 0 258 010 528 Lambda Sensor is a precision oxygen sensor designed to monitor exhaust gas composition and provide critical air-fuel ratio data to your vehicle's engine control unit. As a genuine Bosch component, this sensor delivers the OE-quality performance and durability that has made Bosch the world's leading oxygen sensor manufacturer since pioneering the technology in 1976.

Key Features:

• Precise oxygen content measurement for optimal air-fuel mixture control
• Advanced planar sensor element with integrated heating element for fast light-off
• High-temperature resistant ceramic construction for reliable performance under harsh conditions
• Four-wire design with integrated heater for improved response time
• Helps reduce emissions and improve fuel efficiency
• Direct replacement OE sensor for specified applications

By continuously measuring the residual oxygen content in the exhaust gas, this lambda sensor enables the ECU to maintain the optimal stoichiometric air-fuel ratio of 14.7:1. This precise control supports efficient combustion, maximizes catalytic converter performance, reduces harmful emissions, and helps ensure compliance with on-board diagnostic requirements. The integrated heater allows the sensor to reach operating temperature quickly, enabling faster closed-loop fuel control.
