Error code P0136

[Paramedic]

Hey guys,
I just got a P0136 error code and was wondering if any of you would know what it is and what to do about it?
thanks !

A simple Google search would give you answer. But here, I looked it up for you and found a thread. Sounds like your downstream O2 sensor after the catalytic converter.

would it be odd that my gas mileage seems to be about the same? If I don't accelerate too fast I can about 500/525 km to a tank.....
