Techron fuel injector cleaner and check engine light?

Anyone run a fuel injector cleaner like something like techron (the ones that contain PEA) and got a check engine light? I picked up a 2006 mazda3 with the 2.3L and has about 95,000 miles on it. decided to run a tank of techron and got a check engine light half way thru. not sure if its related but was just curious. i dont have a scanner rn so i cant check but will in the next few days.

I assume maybe a piece of gunk or carbon that broke off hit an o2 sensor or something or maybe the fuel system doesnt like the cleaner or something.
 
what code?

With no code, your guess is as good as anyone.

I would say clear the code and run the current tank down and then a fresh batch of gas.
