This code is for a low voltage on the EGR.

I am attaching the testing that we need to run through in order to figure out what the issue is. However, we need these couple of guides to help do this type of testing.

Please see the info below on the description and testing that you need in order to figure out what the issue is.

Let us know what questions you have, and we can go from there. Thanks
