Bosch Oxygen Sensor Heated Sensor

The Bosch heated oxygen sensor (also called an O2 sensor or lambda sensor) measures the amount of oxygen in the exhaust stream. It sends that data to the engine control unit so the unit can fine-tune the air-fuel mixture. Accurate readings help the engine run efficiently, keep emissions low, and perform consistently.

Key Features:

• Built-in heating element brings the sensor to operating temperature quickly, so the engine control unit can enter closed-loop fuel control sooner after a cold start
• Precise exhaust gas measurement supports good fuel economy and proper combustion
• Helps the vehicle keep its emissions control system working correctly
• Made by Bosch, a long-time original equipment supplier to automakers worldwide, to meet demanding quality standards
• Built to withstand high exhaust temperatures, vibration, and exposure to road contaminants

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