HI,

I am sorry that you have not been helped yet. I just came online and saw your question

Ok, did the check engine light come on with those codes shortly after the K&N filter was installed?

And I need to get the exact fault code numbers.

I am so sorry there has not been an expert to assist you yet!

Hello, my name is***** will be helping you out! I have over thirteen year of experience in the automotive industry for numerous different makes & models. I enjoy doing what I do, it is my life.

P0402-What about the EGR cooler, did you check if the passages were not clogged up? (see attachment)

P0461-That is for the fuel level sensor isn't it? (fuel pump assembly), lets worry about the EGR code first.
