Check Engine Light On? Could Be A Faulty O2 Sensor

Car Care Check Engine Light Advice

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.

    I was very pleased with Lunar Low's prompt service and fair pricing. I was able to get my car in on the same day that I called, and it took them less than 30 minutes to diagnose the issue and give an estimate. An hour later, the work was complete. Very happy with David's professionalism and Wayne's explanation of what he saw with my car.

    I could not be happier with my experience at Lunar Low. It was great taking my car to a shop I could trust and the cost was a fraction of the quote I had gotten at another shop. I would not hesitate to take my car back to David and Wayne. As a female it is great to have a place I can trust!!!

    Took my Jeep to these guys on a recommendation from a friend and after 2 visits (for separate issues), my jeep is on the road again with no issues that I can find. I had my transfer case replaced, front differential rebuilt and an axle bearing replaced. They didn't promise more than they could deliver and delivered on what they "promised" and they're very competitively priced. I would not think twice to take my jeep there for repairs. Thanks Lunar Low for a job well done.
