Techron and code P1415

Was wondering if Techron can damage the O2 sensors? I have a 1999 FRC with 13k on the clock, once a year I pour a bottle of Techron in the tank which I did on Monday and today the car set a P1415 code which indicates an air problem on the right cylinder bank. Could be check valves or possibly o2s. If it were o2s doesn't that set another code? Any thoughts? TIA!!!!!!!!!!!!!!

If it is a check valve, then no, the Techron has nothing to do with it.

I rechecked my codes and P1415 is listed as Bank 1 which I believe is the driver side, am I correct so far? I disconnected the hose from the check valve and determined that the air pump is working. I then removed the check valve off the air tube pipe and blew into both ways and air only flows one way. Does anyone know how this check valve works, is it working properly?

Did you replace all four O2s or just the driver side?

I frigging jinxed myself. I set another 1415 a while ago. I replaced the two front O2's. My rears are turned off. I guess at this point I still have some diagnostics to do.
