I have a few codes P0154, P0134, P0161 P0141 P0156 they're pretty much all related. o2 oxygen sensor or circuit sensor. Yet no check enline light, no rough idle, no bad MPG, car runs great. Should i still get it checked? Or change the sensor? Or juste delete the codes and see if they come back?

I'm not to worried as the car runs great, but maybe i should get it checked before i actualy run into problems, unless i erase the codes and they don't come back, if so, then no need to check it.

Thanks for the help

 

I would try clearing them and see if they come back. If they do, definitely get it checked asap so you don't potentially ruin the cat.
