Maybe this information is in the paper version of the service manual, but for some reason despite being told we were to get one it has never shown it's head! I'm just trying to find a simple way to access this information, seems SIS is very fussy about formats used when searching for something like this error code. And using the 'Advance Full Text Search' section of SIS with a copy and past of part of the information I found on Google I finally was able to get the following form: UENR This gave me some simple things to check and the problem did turn out to be the pre-cleaner, it looked nice and clean on the top but when pulled out it was very dirty. After doing a Google search I did find reference to just this problem. Thought it should be easy but I was stumped as to how to find the information. Several minutes later operator came back and said the code was back! Tried to use Cat SIS to find information on the code, as to what other things may trigger it. Installed new one and thought the problem was solved. Cat 'Error Codes' finding what they mean and Seemed to be obvious that it was trying to say 'Plugged Air Filter'.
