2009 Genesis sedan 3.8L oil in O2 sensor connecter.

[bmenna1]

Engine light came on and there was oil in the connecter end of O2 sensor on passenger side down stream just past the catalytic converter. What would cause this? Do I have oil running through harness?

Looks nobody answered this I jus found the same issue was comin to look for answers.fid u ever figure out what to do about that

What is the OBDII code? That might lead to the sensor that is leaking oil into the wiring harness.

I'm trying to change the bank 1 sensor 2 now and the wiring connector had oil or something in I cleaned it out as good as I could I did have my valve cover gaskets replaced a few weeks ago they were leaking a little bit idk if that why it was in there or what

 

[joegr]

Are you getting all of those codes and not any others? It looks like there was one at the top of the first page that isn't showing.

Thats it

 

[joegr]

Thats it

So, what is the actual code that you are getting?

 

[purg]

I put picks on here can u not see them

Do you want help? Your pictures just seem to show a bunch of codes that might be related to the problem that they think you have based on the code that does not show in your posted picture as it is cut off at the top. Could you just type in the five character OBDII code? I assume that it starts with "P" and the the remaining four characters are numerical.

Yes I would like help but I'm not sure what ur talking about lol

The code at top says p0036 says bank 1 sensor 2 fault that's the one I'm changing

I'm not a mechanic or anything close I have been doing some repairs and so far I'm doin ok I think now if I can get this sensor off I'd be doing a little better lol idk how I'm gonna do the upstream yet

Go back and look at the picture you posted. It's not on there, other than as one of many possible very different codes.


P0036 indicates a problem with the bank 1 secondary O2 sensor heater CIRCUIT. It might be the O2 sensor that it at fault, but often it is the wiring or even the ECM itself. There are troubleshooting steps to determine which it is before throwing a part at it. At the very least, you could measure the resistance of the heater in the O2 sensor to see if the problem is the sensor or not.

[purg]

I took the 39210 in upper right of the pic off is that a downstream ?

 

[purg]

They don't look the same one on top is the old one

It's a different brand. Usually on these. it is best to get the OEM part.
