Skyward Automotive Products Upstream Oxygen Sensor

The Skyward Automotive Products Upstream Oxygen Sensor (also called an upstream O2 sensor or air/fuel ratio sensor) is a replacement emissions and engine-management part. It mounts in the exhaust ahead of the catalytic converter. There it measures the oxygen content of the exhaust gas and sends that reading to the engine control computer.

Key Features:

• Accurate exhaust monitoring: Oxygen content in the exhaust is a good indicator of combustion efficiency. The engine computer uses this signal, along with other sensor inputs, to adjust the amount of fuel delivered.
• Built to OEM expectations: Skyward (SKP) oxygen sensors are described as meeting or exceeding OEM specifications and made under rigorous quality control.
• Replacement-ready design: Each sensor is made as a direct replacement for the original upstream sensor. It threads into the exhaust and connects through a wiring harness and plug.
• Multiple configurations: The line includes different part numbers and connector or wire configurations, so each sensor can match the original on the vehicle.

A worn or failing oxygen sensor can cause poor running, higher fuel consumption, increased exhaust emissions or a lit check engine light. Replacing it helps restore proper fuel control and emissions performance. Allow the exhaust to cool fully before removal, and take care not to damage the threads or wiring.
