Bosch Sensor

Bosch oxygen sensors, also called O2 sensors or lambda sensors, monitor the oxygen content in your engine's exhaust. They send that data to the engine control unit so it can keep the air-fuel mixture accurate. A working sensor supports efficient combustion, good fuel economy, low emissions and smooth engine performance.

Key Features:

• Available in heated wideband and premium original equipment replacement designs
• Heated sensing elements reach operating temperature quickly, which helps closed-loop fuel control start sooner
• Wideband versions measure a broad range of air-fuel ratios, and the 5-wire design supports precise readings
• Premium versions are built as OE-style replacements that match original equipment performance
• Made by Bosch, a long-standing supplier of sensor technology to automakers

A worn or failing oxygen sensor can cause poor fuel economy, rough idle, a check engine light and higher emissions. Replacing it with a quality Bosch sensor helps restore the engine management system's accuracy.
