Most cars produced for the American market after 1980 have an air fuel ratio sensor, also known as an oxygen sensor. This device is part of the emissions control system and provides a data stream to the computer that manages your fuel ignition. By detecting the amount of fuel vapor in the air stream going to the engine, the air fuel ratio sensor can tell the computer whether it needs to adjust the fuel mixture to be richer or leaner. Every fuel has a slightly different formulation, but your air fuel ratio sensor is concerned primarily with ensuring that the fuel to air mixture is at the correct level for your engine. Depending on the engine, the ideal air to fuel mixture is about fifteen to one, meaning fifteen parts air to one part fuel. If the engine receives less fuel than this, it has a hard time combusting, producing poor performance and possibly damaging the engine. A too-lean mixture also produces excessive nitrogen-oxide pollution from your tailpipe. A too-rich mixture is just as bad, however. The unburned fuel creates pollution of a particularly nasty type, spewing gasoline directly into the air. To avoid both of these problems, it's important to keep your air fuel ratio sensor in good working order. A sensor failure will often be detected by the onboard computer, and will result in a check engine light or similar diagnostic message. You may also be able to detect a failing sensor if your fuel efficiency or observed engine performance begin to fall off without some other explanation. Replacing a broken or failing air fuel ratio sensor is not a particularly complicated job but it is critical to get the right sensor for your car or truck's engine control computer. Sensors are not generic parts and each engine computer has its own line of sensors. Be sure to get the right part to keep your engine working at its peak performance for year after year.

Air Fuel Ratio Sensor Information

A properly installed Bosch Air Fuel Ratio Sensor examines the oxygen level that is feeding your car's engine cylinders.




Usually the hardest thing about repairing a vehicle is finding a dependable source for quality parts such as a Bosch air fuel ratio sensor. Take your car to a superlative level of power and performance by installing performance parts. It doesn't matter if you race your vehicle or just enjoy driving a performance vehicle, the best quality aftermarket and OEM parts are critical. Auto enthusiasts who love optimized vehicles recognize that nothing is more crucial than having the highest quality replacement parts for your vehicle. A properly installed air fuel ratio sensor continually tracks how much oxygen that is forced your car or truck's engine cylinders. In cases where the air-fuel ratio is too low, poor performance will be the aftermath; at the same time, a too-rich ratio leads to excessive wear to your engine and unwanted air pollution from the car or truck's exhaust system. The air fuel ratio sensor has a crucial job: getting the engine to function productively without making exorbitant emissions. The air fuel ratio sensor calculates the air-fuel ratios in the engine, keeping them within established ranges for optimum performance.



A high quality Denso Air Fuel Ratio Sensor examines the oxygen level that is going your Denso's engine.




The perfect parts for the job, like a Denso air fuel ratio sensor, are just a few clicks away when you get them from PartsGeek. Your high-performance vehicle demands the best replacement parts that are available. No matter if you race or just enjoy driving a performance vehicle, premium quality aftermarket and OEM parts are crucial. An automobile's performance is the culmination of several factors including high quality parts. The air fuel ratio sensor has a vital responsibility: getting the vehicle to work effectively without causing unreasonable pollution. When your car or truck's air-fuel ratio is too lean, poor engine power will be the result; conversely, a too-rich ratio leads to wear to your engine and excessive air pollution from your car or truck's tailpipe. A high quality air fuel ratio sensor examines how much oxygen that is forced your vehicle's engine cylinders. A car's air fuel ratio sensor keeps track of the air to fuel levels in the motor, keeping them within established ranges for good operation. Your car or truck is really only as good as the parts it uses, such as a Denso air fuel ratio sensor.



A properly installed Walker Air Fuel Ratio Sensor monitors how much oxygen is going your Walker's engine.




If you're in the market for a Walker air fuel ratio sensor, restoring your car or truck with first class parts always pays off in the long run. Your car is special due to its excellent performance and great style, so to have it humming in its best condition you want the ultimate in quality parts and accessories. You purchased that high-performance car because it had high-end engine power and performance, support that investment by buying only the best new parts and accessories. To add to the horses of your vehicle's motor, add a selection of these optional components that are specifically built to raise performance. The air fuel ratio sensor has a key duty: getting your vehicle to function efficiently without causing unnecessary exhaust. A properly installed air fuel ratio sensor continually tracks how much oxygen is forced your vehicle's engine. If the air-fuel ratio is not adequate, reduced combustion will be the consequence; in addition, a too-rich fuel mix leads to wear to your engine and unwanted pollution from your vehicle's tail pipe. Because an inaccurate air fuel ratio sensor may wreck your finances by running too rich or too lean, replacing it will lower your stress over time.
