Codes
Over the last couple of months I have noticed a bit lower than normal MPG. I had checked the codes the other night and just had P0654 H. Before shutting off after my drive into work today I checked the DIC to see what codes were present. It had the following P0161 C, P0654 H, P1416 C. I did not clear any codes before shutting it off.
When leaving work I also decided to check the codes. At that time after starting the motor the following codes were present P0654 H and P1416 C. The check engine light is not on.
What do I need to check into to resolve these codes. I looked up the P1416 and P0161 codes which refer to bank 2 O2 sensors.
Thanks for the help.

P1416 is your code for the secondary air injection system.
P0161 is your code for a Heater Performance Bank 2 Sensor 2.
There are two check valves in the air injection system which tend to go bad. I am not saying this is your problem but it deserves looking into. There is one on each side of the engine. The one on the passenger side is behind the intake manifold and is a B#$%H to get to. The one on the drivers side is easier to get at.

As to the P0161 I am not familiar with that DTC. But in your first part of the post you list it, but not in the second. Am I to assume it has cleared? If not, maybe someone else will chime in. Good Luck.

Well on the way to work this morning I got a check engine light. Checked the codes and the same ones are there. The p1416 does have H C after it now.
I am going to clear these before heading home to see what pops up.
Looks like I may have a check valve replacement in my future.
Thanks for the help.
