DENSO Air-Fuel Ratio Sensor - Direct Fit, Heated Lead

The DENSO Air-Fuel Ratio Sensor (also called an A/F sensor or wideband oxygen sensor) is a direct-fit replacement that helps your engine management system keep combustion efficient. It measures the air-fuel mixture in the exhaust stream and sends that data to the engine control module. The module uses it to adjust fuel delivery for good performance, fuel economy and emissions control.

Key Features:

• Direct fit design: Built as a plug-and-play replacement with the correct connector and wiring, so no cutting or splicing is needed.
• Heated sensing element: The integrated heater brings the sensor to operating temperature quickly. This allows accurate readings and closed-loop fuel control soon after a cold start.
• Wideband response: Gives the ECM precise, continuous air-fuel ratio data across a broad range of operating conditions.
• OE-quality construction: DENSO is a leading original equipment supplier to automakers worldwide. Its aftermarket sensors are engineered to meet the same fit, form and function standards.

A worn or contaminated A/F sensor can cause a check engine light, poor fuel economy, rough running or higher emissions. Replacing it with a quality DENSO sensor helps restore proper engine management performance. Select the correct part number for your application from the options listed on this page.
