I got code P2270 the other day which is O2 sensor stuck lean bank 1 sensor 2. I am going to clean the throttle body and replace the fuel filter to make sure that it isn't a fuel pressure problem. I also looked at the O2 sensor (passenger rear right?) and it looks like there is a oily substance on the connnecter, so I was thinking about taking the intake cleaner and spraying the connecter and wiping them off to see if it was a bad connection.
Is there anything else that could cause this code before I go and spend like $70 on a new O2 sensor?
 






I have seen this codes many times at the dealer and the o2 sensor always fixes it.
 






Thank you. Am I right about it being the passenger side rear O2 sensor?
