DENSO Air/Fuel Ratio Sensor Direct Fit Heated Wire

The DENSO Air/Fuel Ratio Sensor (also called an A/F sensor, wideband oxygen sensor or lambda sensor) is a direct fit, heated sensor. It measures the oxygen content of the exhaust stream and sends that data to the engine control module. The ECM uses it to fine-tune the fuel mixture for efficient combustion, lower emissions and steady engine performance.

Key Features:

• Direct fit design: Built to replace the original sensor without modification or splicing, which keeps installation simple.
• Heated element: Brings the sensor to operating temperature quickly. This allows accurate readings and closed-loop fuel control soon after a cold start.
• Wire connector: Comes with a wiring harness and plug that match the original equipment connection.
• Accurate air/fuel measurement: Gives the ECM fast, precise feedback across a wide range of air/fuel ratios.
• OE-level quality: DENSO is a leading original equipment supplier to automakers worldwide. Its sensors are engineered to meet demanding standards for durability and performance.

A failing air/fuel ratio sensor can cause a check engine light, poor fuel economy, rough running and failed emissions tests. Replacing it with a DENSO direct fit sensor helps restore proper fuel control and engine efficiency. Select the correct part number for your application from the variants listed.
