Research on Air Fuel Ratio Sensor for Toyota Sienna

Even after years of being launched, the Toyota Sienna is still top of the class among minivans. The car not only looks great on the outside its comfortable interior can seat eight easily. The Toyota Sienna is the only minivan to offer all-wheel drive, which is a bonus for those who don't like minivans that much. The state of the art entertainment system that comes with the car is sure to keep your children glued to their seats allowing you to concentrate on your driving. Your Toyota Sienna is also fitted with air fuel ratio sensor which is an important sensor that is installed in most modern car engine management systems.

What Does Air Fuel Ratio Sensor Do?

This sensor constantly monitors the air coming into the motor and sends messages to the car's electronic control unit about the exhaust exiting the car. With the help of this the electronic control unit makes on the spot adjustments to timing and fuel to obtain the maximum efficiency and power of the vehicle.

Do All Cars Come with an Air Fuel Ratio Sensor?

Most of the recent cars come with air fuel ratio sensors installed in them to control the fuel and air mixture. The older cars however, had an oxygen sensor which performs the same function as an air fuel ratio sensor, but it's unable to send data to the electronic control unit. There are many conversion kits available in the market that can be used to install an air fuel ratio sensor in older cars as the oxygen sensors are not very effective.

What are the Issues That May Occur with an Air Fuel Ratio Sensor?

Very rarely you will come across something wrong with the air fuel ratio sensor. The main problem occurs because it gets worn down from prolonged use with exposure to fuel, air, chemicals and other pollutants. There are times when it gets clogged which affects the sensing of the incoming air or outgoing exhaust. The sensor does not experience any other issues unless is gets moved or manipulated during maintenance.

How Would You Know If Something Has Gone Wrong with your Toyota Sienna Air Fuel Ratio Sensor?

The easiest way to get to know if there is something wrong with the air fuel ratio sensor is, if your car's electronic control unit picks up on the issue and lets you know with the help of warning lights on your dashboard or through trouble codes. The other things you may notice are your car will not accelerate the way it used to. You may also get strong exhaust smell. However, if the issue is not fixed quickly then it can go ahead and cause extensive damage to other engine parts leaving you with a huge hole in your pocket.

Are You Thinking Why Air Fuel Ratio Sensor Is So Important?

Air fuel ratio sensor is no doubt very important for your car's health as well as performance. Along with that it also ensures that your car stays well inside the growing restrictions on vehicle emissions necessary to protect and save our environment.

So now that you know all about the air fuel ratio sensor and how important it is for your car's health as well as our environment, if you need to replace it visit PartsGeek.com where you are sure to find the best deal.

Reviewer: "G" Air/Fuel Ratio Sensor

I took my 2001 Toyota to have a check engine light looked at and fixed. I knew it was an Air/Fuel Sensor, but needing a Smog Test also, I took it in. Estimate, $500, the part alone was over $200. I looked around and found the OE part on Parts Geek for $115. I ordered it and it arrived two days later. It was the part needed, Smogged and happy.
