Bosch Oxygen Sensor Heated Universal

The Bosch Heated Universal Oxygen Sensor (O2 sensor, also called an air-fuel ratio or lambda sensor) monitors the oxygen content in your exhaust and sends that data to the engine control unit. The ECU uses it to fine-tune the air-fuel mixture. That helps with fuel economy, emissions control, and smooth engine performance.

Key Features:

• Heated sensing element reaches operating temperature quickly, so the engine can enter closed-loop control sooner after a cold start
• Universal design with a wire harness that is spliced into the vehicle connector, so one sensor can cover many applications
• Built to resist heat, vibration, and exhaust contaminants
• Supports accurate fuel metering, lower emissions, and a steady idle
• Made by Bosch, a long-time original equipment supplier of oxygen sensors to automakers worldwide

A worn or failing oxygen sensor can cause poor fuel economy, rough running, and a check engine light. Replacing it helps restore proper engine management. Choose the specific part number from the available options to match your application.
