P0174 Code?!?

Hi Everyone,

Getting a p0174 Code in my 07GC 3.7l, (bank 2 lean) I've googled the hell out of it and still have no idea what to look for.

Jeep is running great, just the code.

Also I can't seem to do the keydance on my 07 like my 04, did they take that functionality away?

Thanks All.

I did that, or at least I think I checked them all. Anyone have a vacuum diagram for this engine?

Okay, checked all the vac lines I saw. Everything looked okay. Cleared codes, went for a drive light came back on, now it's lean in both banks. Any other ideas before I call the stealer?
Also got the key dance working.

Re: P0174 Code?!?

what about the intake etc? no leaks etc? Could be a bad 02 sensors or 02 harness

I didn't see any places that looked like they would leak. Also did not hear any sucking. Maybe I will have the system smoke tested before going to the dealer.
Also, everything I have read said o2 sensors are a common misdiagnosis.

I don't have the tools to check pressure. Looks like I'm stuck taking it in. Unless anyone with the tools is in northern Illinois that's wants to help a fellow "Jeeper" out.
