What is an Oxygen Sensor?

An oxygen sensor is a device that measures the amount of oxygen in the exhaust gas of an internal combustion engine. This information is used by the engine's computer to adjust the air-fuel ratio, which is the ratio of air to fuel in the engine's cylinders. The correct air-fuel ratio is important for optimal engine performance and fuel economy.

Symptoms of a Bad Oxygen Sensor

There are several symptoms that can indicate a bad oxygen sensor, including:

• Check engine light is on
• Poor engine performance
• Increased fuel consumption
• Rough idling
• Stalling

Causes of a Bad Oxygen Sensor

4. Screw in the new oxygen sensor.
5. Reconnect the electrical connector to the oxygen sensor.

Benefits of Replacing an Oxygen Sensor

Replacing a bad oxygen sensor can provide several benefits, including:

• Improved engine performance
• Increased fuel economy
