Replacement O2 Sensor

A replacement O2 sensor is essential to a vehicle's fuel injection and emission control systems. The replacement O2 sensor helps keep the internal combustion process inside the engine healthy. The air to fuel ratio is measured by the replacement O2 sensor.

A replacement O2 sensor will tell you if the engine is running rich or lean. If the engine is running rich, it means more fuel than air, and if it is running lean, it means more air than fuel in the mixture. The replacement O2 sensor helps determine the right ratio. Replacement O2 sensor is not located in the engine but instead in the exhaust. The replacement O2 sensor takes measurements from the exhaust stream. For example, rich mixture means a demand of oxygen and vice versa. The replacement O2 sensor specifically measures how much oxygen is needed to completely oxidize the remnants in the exhaust gas stream. This is how the replacement O2 sensor, coupled with the catalytic converter, helps with emissions control.
