Had a problem this past weekend with the check engine light coming on.Took it to Autozone,came up with O2 sensor.The car was running fine,gas mileage is nearly spot on to where it should be and the weather we are having now I kind of figured that something had tripped the car to set the O2 sensor off. I removed the negative battery terminal for 30 seconds and put it back on and the check engine light went off and has not came back on. I've put around 300 miles on it since and the car is running as it should.No rough idle or change in gas mileage.
Had an oil change done yesterday and had them check said O2 sensor and was told there was no problem with it and it looked fine. Should I go ahead and change it or wait it out and a little longer and see what happens?
I have the 2010 2.4L 5 Speed auto transmission with 133,500 miles on it. I will also note there was no loss of power when the engine light was on and that has not changed.Still has the same get up and go as when I first bought it.
I average about 21 mpg in town driving and it's a lot of stop and go driving at that.I rarely do any highway driving.
