If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be fewer accurate when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2020 Toyota Sequoia's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to indicate the right mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
