i took my 01 H.O cummins into the shop and tried scanning its codes cuz the check engine lights on. and it wouldn't read my OBD sensor. the fella that checked it said hes ben doin it for a long time and never seen that. said i should check for recalls on my vin. has anyone else heard of or had any problems like this??

 

I had the same thing happen about a year ago. I took it to my cummins guy and he said that there was more than likely an error in the computer. He had me pull the battery cables for 2 hours. It rest it and have not had a problem like that again.

 

allright ill give that a try thanks!
