So I have a P0037 error code which seems to be the oxygen sensor (low voltage). Is this an easy fix? As in could I do it myself. And how soon should this be fixed?

Without knowing a ton about that cel code, replacing an oxygen sensor is pretty easy. You just need to find the faulty o2 sensor then its a plug and unscrewing the o2 sensor itself. All of these sensors are on the exhaust system. Good luck!
