Occasional engine light

So am i correct that the general consesus is the 02 sensor must have a signal or my economy would be up around 16-17lph, even though i am getting a CEL every few days? That being the case i think I should be right to not worry because obviously there is no real problem with the sensor? It must be something else causing tbe error 13?

I could have it gas anylised if i find a place who has the tool.

So I get a CEL most days that I drive the ute. It seems to be under load at around 2.5 -3k rev range and more often than not it is when going up hill. I'm wondering if it is an issue with the valve body and the code flashing but is just not logging??
