DENSO Oxygen Sensor Heated Direct Fit Wire

The DENSO Heated Direct Fit Oxygen Sensor (also called an O2 sensor, lambda sensor, or air/fuel ratio sensor) monitors the oxygen content in your exhaust and sends that data to the engine control module. The ECM uses it to fine-tune the air/fuel mixture, which supports fuel economy, smooth engine performance, and emissions control.

Key Features:

• Direct fit design: Built to the original equipment connector and wiring configuration, so installation is plug-and-play with no splicing.
• Heated sensing element: An integrated heater brings the sensor up to operating temperature quickly. This allows closed-loop fuel control sooner after a cold start and helps lower cold-start emissions.
• OE-quality engineering: DENSO is a leading original equipment supplier to automakers worldwide. Its sensors are designed to match OE form, fit, and function.
• Accurate, fast response: Delivers stable signal output for precise fuel metering across a range of operating conditions.
• Durable construction: Made to withstand high exhaust temperatures, vibration, and road contaminants.

A worn or failing oxygen sensor can cause poor fuel economy, rough idle, hesitation, increased emissions, and a lit check engine light. Replacing it with a quality direct fit DENSO sensor helps restore proper engine management and efficient operation.
