Check Engine Light On? Could Be A Faulty O2 Sensor

Check Engine Light On? Could Be A Faulty O2 Sensor



According to the annual CarMD Vehicle Health Index one of the most common check engine light repairs is replacing the oxygen sensor. This relatively minor repair can be costly if neglected, leading to as much as 40 percent lower fuel efficiency, causing further damage to your vehicle's exhaust system and adversely impacting the environment.



Vehicles with faulty oxygen sensors typically seem to drive and handle well, but the malfunction can dramatically decrease fuel efficiency and lead to costlier repairs if ignored. A faulty oxygen sensor means your vehicle is emitting more pollutants and if the check engine light is illuminated, it may not pass vehicle emissions testing in those states requiring it for vehicle registration.



A vehicle's oxygen sensors are mounted in the exhaust system; they monitor the catalytic convertor's operation and the level of oxygen in exhaust gases to maintain efficient engine operation. The best way to prevent an oxygen sensor failure is to follow a regular service schedule, including routine oil changes.



Unlike the past nine years of the annual CarMD report, costly catalytic converter replacement edged out O2 sensor replacement as the most common check engine light repair. Catalytic converters do not typically fail unless maintenance and other repairs are ignored or the vehicle is older. Average vehicle age has increased from 10.6 years to 11.7 years over the past decade, contributing to this outcome.



It is important that car owners check the reason for an illuminated check engine light without delay and make necessary maintenance to avoid more costly repairs, like catalytic converter replacement, down the road. If you find your vehicle needs service, call your trusted local repair shop.

reviewiconBetter Than A Dealership

Great place to get your car serviced! I went in for an estimate and they were able to have it fixed the next day! They told me ahead of time that there could be more problems when they got it on the lift so that there were no unexpected expenses which is great! Bottom line- if you need your car repaired, come here.

reviewiconFast and Courteous

Went in knowing what I wanted done and let them know the issues I'm trying to fix. They respected it, suggested possible other fixes if the requested didn't fix it, but didn't get pushy. Got me in and out pretty fast despite being a walk in. My only regret is I hadn't gone to them years ago. Could've saved so much money and headaches if I went with them
