I just recently purchased a OBDLink MX+ Scanner and the Forscan Lite App and I have a newby question. I have received elevated results on the "Inferred Catalyst Mid-Bed Temperature" section of the Mode 6 Test. I was hoping that someone more familiar with Forscan may be able to shed some light on what exactly this section of the test is and are there any other PIDS that I should be monitoring to help diagnose a potential issue? Any insight would be appreciated.

 

There are year specific forums which better serve non-general F-150 issues/topics..

 

Download and read the OBDII theory manual from www.motorcraftservice.com so you can get a better idea of how the system works.
