My max had an engine light lit up and it putted out a code for O2 sensor problem. My local mechanic reset it twice. There is no engine light on for about one year. Should I check on the O2 sensors or just clean the sensors.

 

huh... you just and a check engine light for an o2 sensor. The mechanic just reset it twice. and there's no check engine light for a year? Is this a terentino movie? Timelines a bit off...

 

yep, i thought it maybe strange that why i'm checking with you folks here.
