SES Light Help

2001 I30

The car is running great and mileage is the same.

The SES light came on. I took the car to Auto Zone and they cleared the code and the light was off for about 300 miles. I was driving on the highway and it came back on. Auto Zone said the fault was the O2 sensor high volts. What does that mean? Will I damage the car if I just keep driving and not fix the light?

Thanks for your response.

you wont damage too much. you just need to find out which O2 sensor it is, replace it, and then clear the code.

I was not aware that it would cause damage. What will be damaged??

How difficult is to install the O2 sensor? How many does my engine have?

How can I clear the code?

you should only have three :Bank one sensor one (coming off exhaust manifold in back of engine)Bank two sensor one (coming off eshaust manifold in front of engine)Bank one sensor two (behind or in catalytic converter)

in the instance that you have four (meaning two behind the cat) then you have california emissions and not federal emissions and by the way, it wont damage anything. you'll just start losing gas mileage until you get it fixed. once you replace the O2 Sensor, go to advance auto parts to have the code cleared. keep in mind that if you ask us to do that that we put the code scanner on there and you are supposed to hit the final button that clears the codes. that will just keep us out of trouble.
