ACDelco GM Genuine Parts Heated Oxygen Sensor

The ACDelco GM Genuine Parts Heated Oxygen Sensor (also called an O2 sensor or lambda sensor) measures the oxygen content in your engine's exhaust and reports it to the engine control module. The module uses this signal to fine-tune the air-fuel mixture. That helps the engine run efficiently, keeps emissions low, and supports good fuel economy.

Key Features:

• Genuine GM Parts quality: Engineered to meet General Motors original equipment specifications for fit, form and function.
• Heated sensing element: An internal heater brings the sensor up to operating temperature quickly. This allows earlier closed-loop fuel control after a cold start.
• Accurate signal: Gives the engine computer dependable exhaust feedback for precise fuel metering.
• Emissions support: Helps the engine and catalytic converter work as designed.
• Plug-and-play design: Comes with the connector and wiring pigtail for a direct replacement, with no modification needed.

A worn or failing oxygen sensor can cause a check engine light, rough idle, poor fuel economy, and increased emissions. Replacing it with an ACDelco GM Genuine Parts sensor helps restore the engine's fuel control and emissions performance.
