Delphi Heated Oxygen Sensor Lambda Sensor

The Delphi Heated Oxygen Sensor, also called a lambda sensor or O2 sensor, measures the oxygen content in the exhaust stream. It sends that data to the engine control unit (ECU). The ECU uses the signal to fine-tune the air/fuel mixture. This helps the engine run efficiently, keeps emissions low, and supports good fuel economy and drivability.

Key Features:

• Heated sensing element: An integrated heater brings the sensor to operating temperature quickly. This allows early closed-loop control after a cold start and helps reduce cold-start emissions.
• Accurate signal response: Delphi designs the sensor to give the ECU a stable, repeatable reading for precise fuel control.
• OE-focused engineering: Delphi is a long-established original equipment supplier. Its aftermarket sensors are built to meet the form, fit, and function expected of the original part.
• Durable construction: The sensor is made to withstand high exhaust temperatures, vibration, moisture, and road contaminants.
• Plug-and-play installation: Each sensor comes with the connector and wiring harness designed for its application, so no splicing is typically needed.

A worn or failing oxygen sensor can cause a check engine light, poor fuel economy, rough idle, and increased emissions. It can also eventually damage the catalytic converter. Replacing an aging sensor with a Delphi heated oxygen sensor helps restore proper engine management and emissions performance.
