Last month the light came on while I was driving the car with the fuel level down to probaly 1 gal or even less. I'd never let that happen before and was hoping that the light would go away with a full tank.
The car has 70K miles, engine has never been repaired or serviced other than fluid and filter changes at normal intervals.
Well the light did not go out when the tank was filled. I had the code checked and it read as an O2 sensor, had the light reset and it came on again within 20 miles driving.
The thing is, the engine is running super strong, no issues at all, in fact it's getting better gas mileage this year than it ever has (a 2 mpg improvement, noticeable about 3-4 months before the SES issue began).
I've read so many horror stories about attempts to correct an SES with ensuing major engine screwups that I'm inclined to use the 1 inch square of electrical tape correction method.
Can anyone comment?
