Have you noticed that you’ve had to stop at the gas station more and more frequently lately to fill up your Toyota Avalon? If so, you might want to check your oxygen sensor to make sure it is functioning properly. Your oxygen sensor is responsible for relaying proper oxygen measurements to your engine computer. If it provides faulty information, then your computer will feed the wrong mixture of fuel and oxygen to your engine. This will lead to a rich or lean mixture that will reduce fuel efficiency. When it comes to replacing your oxygen sensor, you can’t go wrong with Bosch. No other company has more experience manufacturing oxygen sensors than them. That’s because they are the company that originally introduced the first sensor way back in 1976. Now that the oxygen sensor is a standard component, Bosch has continued innovating throughout the years to deliver nothing but the best in design. A Bosch Oxygen Sensor includes a zirconium ceramic bulb that is coated on both sides with platinum. This sophisticated design allows the sensor to more accurately gauge your oxygen emissions. So when it comes to gaining perfect fuel economy for better engine efficiency, go with the experts and get a Bosch.
