What does a bad O2 sensor smell like?
2. Bad gas mileage and rotten egg smell. If the oxygen sensor is going bad, the fuel-delivery and fuel-combustion systems will be thrown off. This excess fuel in the engine can produce a sulfuric, rotten egg smell, and may even produce black smoke from the exhaust.
Do O2 sensors need to be cleaned?
While some people choose to remove them and use a wire brush or an aerosol cleaner to remove deposits, we do not recommend trying to clean O2 sensors. Because catalytic converters are “self cleaning” under certain conditions, they should actually last the life of the car.

Bad O2 sensor symptoms include poor gas mileage, rough engine idle, starting trouble, and even failure of the catalytic converter. Often, the check engine light will come on to provide ODII trouble codes to check with a code reader.
How does a wideband O2 sensor work?
Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel).
