P0051 code replaced sensor and still getting the light?

Question

Looking for the sensor fuse location possibly?

Answer 1

HI there,

There are 2 fuses that could cause some problems. First, under the hood there is a fuse labeled A/F the other fuse is labeled IGN1. Either could be blown. Also, make sure you replaced the correct sensor. The code is referring to the bank 2 sensor 1. This is the radiator side of the engine and the very first sensor, usually mounted in the exhaust manifold or just before the catalytic converter.
