One of many of modern parts found in the vehicle of today that perform various monitoring and adjustments tasks that reduce the need for physical labor and adjustments, your Cadillac Seville oxygen sensor plays a role in helping your air-to-fuel ratio be as efficient as possible. Located just after the combustion system, your oxygen sensor measures the amount of oxygen in the exhaust as it leaves the combustion area after the fuel burn. If the oxygen level as off, it can indicate a problem with the air-to-fuel ratio, which can negatively affect your vehicle performance, and when the oxygen detects an oxygen level outside of the acceptable range, it sends a signal to the main computer of the vehicle.

Your Seville’s main computer then makes adjustments, if needed, to your air-to-fuel ratio. If that main computer does not have access to the information provided by your Cadillac Seville oxygen sensor, due to malfunction or failure, it is unable to make those sensitive adjustments to your combustion system, and your settings will often revert back to the default settings, which are often fuel heavy, and also referred to as rich.

In that case, your vehicle will not be using its fuel as efficiently as possible, and you probably won’t be getting all of the power that it holds, nor will you be achieving your best potential fuel mileage.
