Code P1416 AIR System Bank 2?
The check engine light came on and I found the following current (C) code:
P1416 AIR System Bank 2
Can anyone shed some light on this and let me know how serious it is? Is it fine to reset?
As always, thanks in advance

P1416. One of the HO2S sensors did not respond to the PCM with the expected voltage when the AIR test
was run. The right front HO2S voltage didn't drop below 222mv.
Manual lists carbon buildup in the exhaust manifold preventing proper air flow past the sensor. or problem with the AIR system. I suppose it could also be the sensor. You could swap it to the other side, and see if that fixes it.
Sorry I don't have more time right now. Got to get to work. Hope that helps.

Thanks for the good info. Is this something I need to get checked out? The code hasn't cleared yet so I'm considering resetting the code manually and seeing if it comes back. Is there any harm in this?
Thanks again

The other codes are RH DL Relay circuit fault
LH DL Relay circuit fault
Backup lamp relay circuit fault
All these can be caused by a low voltage condition.
Check your battery connections and condition of the battery. There are also some ground connections in the engine compartment, that may need cleaning. I'm not sure exactly where they are, but somewhere in the area of the battery. Also check for any water dripping on the BCM, from a clogged A/C drain. The BCM is behind the passenger footwell panel.
I don't think it will hurt anything to try resetting the codes. If the condition isn't resolved they will set again. The P code could cause a lean condition, so I would take it easy until you get the problem resolved.
I'm just reading from the manual, and making a few guesses as to what might be wrong. Maybe someone else can chime in here.
Hope you get it resolved.
