It has only 33K. It is good to know that it is still under warranty.
I recalled it said Bank 1 Sensor 1. Anyway, last night I looked under the hood. There is only one sensor easily accessible without any tool. So I kinda checked for any loose wire. Everything seems to be in tact. Amazingly, when I restarted car, the light disappeared :o. I have been driving it for some more that night and this morning. It seems everything is fine (no more check engine light).
Is this possible that it is a false alarm - has anyone seen something like this before? Should I be concerned? Since it is still under warranty, should I bring the car to dealer and have them checked?
Thanks in advance.
