Bosch Oxygen Sensor Sensor Heated

The Bosch heated oxygen sensor (O2 sensor, also called a lambda sensor or air/fuel ratio sensor) measures the oxygen content in your engine's exhaust. It sends this data to the engine control module so the module can adjust fuel delivery for efficient combustion, lower emissions, and good drivability.

Key Features:

• Built-in heating element brings the sensor to operating temperature quickly, so the engine can enter closed-loop fuel control sooner after a cold start
• Designed to give accurate, fast-responding signals for precise air/fuel ratio management
• Bosch pioneered the automotive oxygen sensor and supplies sensors to many vehicle manufacturers as original equipment
• Rugged construction is built to withstand exhaust heat, vibration, and contaminants
• Pre-installed connectors and wiring harnesses on many part numbers help keep installation simple

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 heated sensor helps restore efficient engine operation and supports emissions system performance.
