Frequently Asked Questions
What does an oxygen sensor do?
An oxygen sensor monitors the amount of oxygen in your vehicle’s exhaust and sends that information to the engine control module. The computer uses this data to adjust the air-fuel mixture for better performance, fuel economy, and emissions.
What are the symptoms of a bad oxygen sensor?
Common symptoms include a check engine light, poor fuel economy, rough idle, hesitation while accelerating, increased exhaust emissions, and reduced engine performance.
Can I continue driving with a bad oxygen sensor?
While your vehicle may still be drivable, a faulty oxygen sensor can reduce fuel efficiency, increase emissions, and potentially contribute to catalytic converter damage if left unrepaired.
Will replacing an oxygen sensor improve fuel economy?
If a failed oxygen sensor is causing the engine to run with an incorrect air-fuel mixture, replacing it can often restore proper fuel efficiency and engine performance.
Does Colorado Car Care test the oxygen sensor before replacing it?
Yes. Our technicians perform complete diagnostic testing to verify whether the oxygen sensor has failed or if another engine or emissions system problem is causing the symptoms before recommending replacement.
