DENSO Oxygen Sensor Direct Fit Heated Sensor

The DENSO Direct Fit Heated Oxygen Sensor (also called an O2 sensor or air/fuel ratio sensor) measures the oxygen content in the exhaust stream. It 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 to match the original equipment sensor, with the proper connector and wiring harness. It installs without splicing or modification.
• Heated element: An internal heater brings the sensor to operating temperature quickly. This allows early closed-loop operation and helps reduce cold-start emissions.
• OE-level quality: DENSO is an original equipment supplier to many automakers. Its sensors are built to meet the performance and durability expected of factory parts.
• Accurate signal response: Delivers a stable, precise signal for consistent engine management.
• Durable construction: Designed to withstand the heat, vibration, and contaminants of the exhaust system.

A worn or failing oxygen sensor can cause a check engine light, poor fuel economy, rough idle, and higher emissions. Replacing it with a DENSO direct fit sensor helps restore proper engine management and emissions performance. Select the child item that matches your application for the correct part.
