I went to a mechanic a month ago and replace the alternator because my battery light came on. After about one month, the battery light came on again. I went to the same mechanic and he said that the oxygen senor is faulty. If I unplugged one oxygen sensor and I did not fix that one oxygen sensor. Will the car still run and won’t shut down? What are the problems that the car might cause?
the battery light coming on has nothing to do with an oxygen sensor. I would suggest going to a different shop and having it retested.
An Oxygen sensor has nothing to do with the battery light. If you unplug an oxygen sensor it will still run but have bad gas mileage and the check engine light will come on.
