Do O2 sensors have a warranty?
The O2 sensor is covered for 2 years/24,000 miles under the Federal Emissions Warranty. It may be covered for a longer period under the vehicle warranty terms (as Jest pointed out..) The O2 sensor is covered for 2 years/24,000 miles under the Federal Emissions Warranty.
How often do O2 sensors need to be replaced?
60,000 to 90,000 miles
Newer oxygen sensors are supposed to work efficiently for 60,000 to 90,000 miles, depending on the model of your car. If your mechanic determines that your car’s problem is due to a bad or failing oxygen sensor, the replacement shouldn’t take long and you’ll be ready to tackle many more miles on the road.
How does the O2 sensor work on a Silverado 1500?
Voltage on zirconia sensors drops 0.2 volts when a lean mixture is detected and jumps 0.9 volts when it detects a rich mixture. Many vehicles now feature “wideband” O2 sensors that go beyond detecting rich or lean mixtures. The voltage from these sensors changes in proportion to the amount of change in oxygen levels.
What happens if your O2 sensor is bad?
The engine management computer uses the data from all of the O2 sensors to keep the air/fuel mixture optimized. A bad oxygen sensor can affect the mixture greatly. Without being able to optimize the air fuel ratio, combustion isn’t as efficient, and fuel mileage suffers.
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).
What does the oxygen sensor in your car measure?
The oxygen sensor in your vehicle measures oxygen levels in the exhaust gases exiting the engine.
What happens when the oxygen sensor goes bad on a Chevy Silverado?
Your Silverado can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all. Often enough, the only sign of the problem at all is the service engine soon light being on. The good news is, if you end up discovering that the oxygen sensor is bad, they really aren’t that expensive to replace.

Where is the oxygen sensor in the engine?
An Oxygen sensor that is between the catalytic converter and the engine is known as an “upstream” sensor. Oxygen sensors after the catalytic converter are “downstream sensors”. As a rule, the upstream sensor is more important for engine timing and air/fuel ratios.
How does the power commander fuel tuner work?
With tracking, tuning, and monitoring capability, this fuel tuner can easily and effectively optimize your air/fuel ratio without directly changing the ECU. This makes it super easy to revert back to stock options whenever you need to. Our Power Commander tuning device is a powerful device that can completely overhaul your driving experience.
