A lil' help pls | Check engine ligh on > > >

Just replaced 02 sensors 2 mos ago...(Check Engine Light ON)

Now I am getting P118 | P171 | and P174 code

Checked some site but showing different results.
* coolant
* to reach bank 1 and bank 2

Anyone care to translate in plain English?

Thanks -

It is not a loose gas cap? If it is it will go away after a few days.

Just tighten you gas cap.
