What do you need to fix if p1131 code pops up

Question

Engine not turning over, it will crank but not start

Answer 1

Hi there,

This code is for the heated O2 sensor, bank 1 sensor 1. This should not prevent the truck from starting. It does mean the O2 sensor is seeing a lean fuel mixture, but if the truck isn't firing and starting, this will not cause the no start.
