Various dash codes,

[AABOFFORESTVILLE]

The shop I work at has pulled some codes on the mentioned vehicle, looking for better info per code.

 

PO455

PO496

PO522

 

 

B0100

B0103

I understand that the front collision sensor need replacing due to moisture ruining them, is this correct!

Doesn't your shop have service info of some sort to look up instead of the Internet forum ????

 

Makes no sense to me

I was thinking the same exact thing when I read his post.

 

The shop should be able to tell you what the codes mean. I have a cheap AutoZone scanner that I bought years ago and it displays the numerics for the code, along with the issue. Pretty sure all code readers work that way.
