Code P02E3

[DCorbett]

Just curious if anyone has had this code P02E3 Diesel Intake Air Flow Control Circuit High? The truck runs with no issues and I just returned from a 2,000+ mile trip. I did some reading on it and from what I can gather is the Control Valve is just needs cleaned or replaced. I am planning to remove it to inspect it but time hasn’t been on my side. Just was hoping for any advice from someone that has dealt with this. Thanks

I have not but here are some docs on that and the related valve if needed. Did not get any hits on the code in the search besides this post.

I'm always super cautious doing some probing of the circuts, definitely use caution and good devices for any measurements.

I totally agree on messing with the circuits for sure! I appreciate the reply and will look thru what you posted. I’m sure the valve will need to be replaced due to the fact that I found out thru my research that it’s unserviceable. I need to get one ordered and thought I’d take it off and just see if a good cleaning of the mechanical part of it does anything. I’ll try to post what I find, thanks again!
