Issues after Heater core replacement
I replaced the heater core in my truck this weekend. The only thing I was worried about was pulling the dash. The truck is a 1998 f150 with the 5.4 Everything went fairy well and decided to replace the AT Shift cable as well. Got everything put back. Truck runs, no leaks, no antifreeze smell. After running about 20 minutes, it started idling a little rough and my check engine light came on. The codes are p0136, p0156, p1131, and p1151. I know these are related to the OS sensors. My question is could it be as simple as I miss an electrical connection when putting the dash back in? Was thinking possibly somewhere on the passenger side under the kick plate or possibly something while hooking up the heater hoses? My thought I Amy have missed a ground wire when putting the dash back in. Any thoughts or suggestions would be most appreciated.
