My city/state would not allow license plate renewal with "service engine light" on. Was informed by Nissan that the cause of this would affect both my gas gauge and miles til empty information, however, neither was affected so I waited almost 3 years to have this fixed. Found a way to turn off "service engine light". In cities/states not requiring this, it wouldn't have mattered.

Check engine light keeps coming on and eventually goes off don't know what the problem is but it is very annoying to have this ck engine light coming on every so often had it checked was told it was an 02 sensor before i could take it to get repaired it goes off again what am i suppose to do?
