Delphi Oxygen Sensor Thread-In Sensor

The Delphi Oxygen Sensor (O2 sensor, lambda sensor) is a thread-in sensor that monitors the oxygen content in the exhaust stream. It sends data to the engine control module so the module can fine-tune the air/fuel mixture. Accurate readings help the engine run efficiently, keep emissions low and deliver consistent performance.

Key Features:

• Thread-in design that screws into the exhaust manifold, downpipe or exhaust pipe
• Measures exhaust oxygen levels to support closed-loop fuel control
• Helps maintain fuel economy, drivability and emissions system performance
• Built by Delphi, a long-time original equipment supplier of engine management and sensor technology
• Available in multiple configurations, including upstream and downstream positions

A worn or contaminated oxygen sensor can trigger a check engine light, cause poor fuel economy, rough running and failed emissions tests. Replacing it restores accurate air/fuel feedback and helps protect the catalytic converter.
