Po431 can i still drive with this code comming up

Question

Po431 pops up how long can i drive before it leaves me stranded.

Answer 1

The P0431 is for the catalytic converter. It is difficult to say how long you can drive your vehicle. It all depends how bad is the catalytic converter, but before you can get stranded on the road, you probably will hear rattle noises from the exhaust system and the engine performance will be reduced.
