Hi, I'm new here, but have used the google searches to get info on codes and breakdowns in the past eight months. This has been very helpful to us so far. My husband and I are still new to the owner op business and hope to be successful in it. My concern now, is the 2011Volvo isx we own. We have two codes that are pid 411 and 102. I know what they are, but am trying to determine if the 102 can cause the 411? The complete codes are mid 128 pid 102 fmi 2, and mid 128 pid 411 fmi 0. Currently the truck is trying to regen after the check engine light goes out. Parked regen is impossible so far. Just trying to find out if the boost pressure sensor is making the egr mess up. Thanks in advance.
