DENSO Oxygen Sensor Heated Direct Fit Lead

The DENSO Heated Direct Fit Oxygen Sensor (also called an O2 sensor or lambda sensor) measures the oxygen content in exhaust gas and sends that data to the engine control module. The ECM uses the signal to fine-tune the air-fuel mixture. This helps the engine run efficiently, keeps emissions low, and supports good fuel economy.

Key Features:

• Direct fit design: Built with the correct connector and wire lead for its application, so it installs without splicing or wiring modifications.
• Heated element: An integrated heater brings the sensor to operating temperature quickly. This allows accurate readings and closed-loop fuel control soon after a cold start.
• OE-quality engineering: DENSO is a leading original equipment supplier to automakers worldwide. These sensors are designed to match the performance and durability of the original part.
• Reliable signal response: Delivers fast, consistent feedback to help the engine management system maintain proper combustion.
• Emissions support: Helps the catalytic converter work effectively by keeping the air-fuel ratio in range.

A worn or failing oxygen sensor can cause a check engine light, rough idle, poor fuel economy, and increased emissions. Replacing it with a DENSO direct fit sensor helps restore proper engine management performance. Select the correct part number for your application from the options on this page.
