If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less polite 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 2019 Nissan Altima's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to designate the right mixture of air and fuel that enters the cylinders in your engine.
