The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

My check engine light is on. They say it is the o2 sensor. I was told that if don't properly place on your gas cap this could happen. However, I do want to fix the problem. As a woman, I have learned to not much trust many repair shops. How much is too much for this job.
I had a check engine light with an error code for bank 1 sensor 2; changed the sensor and performed soft computer reset. within 10 minutes light illuminated again; error code for same sensor.
Check engine light on - fix described as "replaced air fuel ratio sensor and cleared code in computer" - $224 labor, $242 parts cost, $22.40 shop supplies. Is this reasonable?
Yes, I have this problem. I purchased an OBDII tool online. When it is time for inspection, I hook up the tool, turn off the MIL light and codes, drive 100 miles, and it passes. Tool is only about $50. There is nothing wrong with the car, runs great, think this is a scam to get you to bring it to a dealer and they charge you $350-$700 to repair, and it still comes on. Then they want to tell you it is something else, and charge you again. Happened to my neighbor.
check engine comes have to change sensor, happens all the time, abs lights also
Failed oxygen sensor. I just ignored it. The check engine light finally stopped coming on about 6 months ago.
Car still runs fine. To eliminate check engine light from staying on, disconnect positive battery cable for 5 minutes, reconnect, then you can dive car (to inspection station) without light appearing for about 5 key cycles.
Check engine light came on. No performance issues that I could tell. They replaced the B1S1 O2 Sensor. The Sensor was welded into place on to the manifold over time and it was really inaccessible. It required a lot of time and labor to complete the repair however it was not done at a dealer. It was done at a small shop.
Check engine light came on few months ago and it was O2 sensor related.
Had to pay $250 to change the sensor........ Sucked!
One sensor failed first and then the other.
Check engine light came on after the dealer overfill the transmission fluid and it leaked on the sensor. Dealer rreplaced it
The "check engine" light came on.....auto repair shop checked the cars computer. It was the o2 sensor accessible from under the car....not sure if I can do the repair myself (hard to reach). The auto shop wanted $220 for the part (plus $85 to install)....I found it on eBay for $78 (Bosch part# 13540).
Check engine light came on. The repair shop said it was a failed oxygen sensor-front, and charged me $202.33 for the part and $97.40 for the labor.
had to replace oxygen sensor gas mileage went up afterward but still not as good as first 50,000 miles otherwise great vehicle...ps all auto shops at dealers that i know of are liars and need to locate good local mechanic jay hicks
Not yet fixed even after $400 or so to fix completed. Do have another appointment however to see about code reading.
The car has the check engine light on I wonder what the problem.
My wife purchased a 2006 Toyota Avalon just after Christmas. The warranty expired on the car last week. After the expiration of the warranty, the check engine light came on while I was driving.
I took the car to a mechanic and the problem was a faulty oxygen sensor. The sensor was replaced. I was driving the car tonight and the check engine light came on again.
My wife's previous car had 125,000 miles on it. She owned this car for ten years and the check engine light never came on during this time.
A car should not be having engine problems with mileage this low.
