Question

What are the engine codes P0301 and B2AAA on my 2010 Chevrolet Silverado 5.3L?

Answer 1

HI there,

This code points to a misfire on cylinder 1. This can be caused by intake manifold vacuum leak, spark plug, ignition coil and once in a while a bad fuel injector or some type of internal engine problem.

Answer 2

The B2AAA code will be set if the OBDII scanner is not compatible with your vehicle.
