Check Engine Light On? Could Be A Faulty O2 Sensor

 1 Verified Review(s)



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.

what our customers say

My truck's water pump gave out, and the serpentine belt flew off on the highway. I had my insurance company tow it to Williams Automotive Inc. I spoke with Jeff, and he informed me of what the damage was. He gave me a best and worse outcome for the fix. It has been my experience that when you are given two options of what may happen from an automotive shop, it's usually the more costly repair that you get to deal with, according to them, when they get back to you about it. However, surprisingly, Jeff got back to me via text with a picture of the object in question and informed me that the cheaper fix will do. I was shocked to say the least, and definitely happy about the good news. I believe they did excellent work, and gave me excellent customer service at a reasonable price. Would not hesitate to go back if/when needed.

10 out of 10 as always. The mechanics do great work, no one tries to up sell you on anything. If a new or potential problem is discovered, while your car is being repaired for the original reason it's being worked on, NO additional or surprise repairs are done without the customer's approval first. Customer service is top notch, always professional and courteous, and the customers are always greeted like family. We will not take our vehicles anywhere else.

Fair, honest, and good to deal with. They could be a bit faster on getting parts, they could be located better. But really in spite of those two things there is no one I would rather trust with my cars. I tried someplace else just to be closer to the hose. That was a huge mistake.
