mooniey Posted May 22, 2014 Share Posted May 22, 2014 Hello new here, I work at a truck shop here in maryland, we work on pretty much anything and everything. Were starting to see some newer macks haven't seen any in a while. The issue is with an 04 ch613 customer keeps having issues with the engine position sensor, and setting codes for cylinder 13,and 14, witch it doesn't have of course. Has anyone had this problem and if so where should I look to try to resolve it and how? Any help would be greatly appreciated.

wheeler73 Posted May 23, 2014 Share Posted May 23, 2014 I agree with the programming issue. I would reflash and program the eecu. If you have to take it to a dealership I would have them call and see if there are any data file upgrades and make sure the vecu is at step 12B.
