E4 Fuel trim bank 2, permissible range exceeded
After struggling a fixing a short (with much help from forum members) in one of my O2 sensors I now get the E4 Fuel Trim Bank 2 error message above. Using my basic scanner I see nothing out of order or non functioning with regard to the O2 system. Internet search is inconclusive as to what would throw this code. Would love some troubleshoot tips.
