SES P1416 could it be an O2 checked the valve
It is not putting any other codes up so I assume the air pump is good, will check it also though if bad it should SES P1415 as well I would think.
Is it possible that the HO2S sensor that should detect the change in emission when the pump is on be bad? I If it is not going below 220mv could this be the problem>? And still give the check valve code?
Which one of the O2's looks at this? location? Thanks for any help.

I cleaned the valves with carb cleaner after I got this code. Good for a year, then the code set again. I just ended up replacing them.
