CEL Code P0171

[Whitey]

CEL Code p0171 Bank 1 - Lean.

I have searched for this and the most likely solution is your o2 sensor before the cat. Someone mentioned about getting them checked to see if they are bad or not, where can I go to get my o2 sensors checked before I go out and buy one?

FYI: this post would be better placed in the "repair and maintenance" forum...

And the P0171 basically does mean the first O2 sensor is faulty, that's that the on-board diagnostics system is for!
