Check Engine Light On? Could Be A Faulty O2 Sensor

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.

Testimonials

Ok, so we all know finding a reliable, trustworthy auto mechanic is like looking for lost treasure: IF its out there, you'll be spending a lot of the time looking. Well Raul's is gold. Raul is the owner and a complete business man with professional service and top quality customer service (and I should know- I work at Nordstrom). I will never go anywhere else. The prices are more then fair and the service is top of the line. I could make a list of all the things they have done FOR FREE. They have loaned me a car, done a diagnostic, checked wiring, picked me up, dropped me off, replaced valves , did research on warranties I could be covered under, EVERYTHING they could without charging me. Last time I picked it up, it had more gas then when i dropped it off. They put GAS in my car and didn't charge me. When does that happen? never. Only at Raul's. I dropped off a 6 pack just because I was that grateful.
