Oxygen Sensor for Audi S4
With fuel prices higher than ever these days, your wallet feels it every time you fill your gas tank. You want to do everything you can to ensure your car is operating at maximum fuel efficiency. One step you can take to get more miles per gallon is to replace your faulty Audi S4 oxygen sensor.
The S4 oxygen sensor assists your car's computer in regulating your combustion cycle. Though it is part of a network of sensors, you will find your Audi S4 oxygen sensor near the exhaust manifold, separate from the other sensors that monitor engine exhaust.
The purpose of the S4 oxygen sensor is to measure oxygen levels in your combustion residue and ensure that your engine uses just the right amount of fuel to operate at optimal efficiency—no more and no less. When your Audi S4 oxygen sensor is not working, your vehicle's computer relies on information from the other sensors, which is not as accurate. Most often the result of a faulty S4 oxygen sensor is a "rich" fuel mixture. Your car overcompensates and injects too much fuel into the combustion chambers, because not enough fuel can damage your engine. A bad Audi S4 oxygen sensor means wasted gas, and it can also lead to a damaged catalytic converter as excess fuel passes through your exhaust system. If your car seems to be using more fuel than it used to, replacing your S4 oxygen sensor is one way to restore lost fuel economy.
