codes...codes....more codes

14, 31, 32, 33, 57, 62, 68, 85. It seems to be running well still, and I believe the temp sensor code is from having a vinyl grill cover, since it was so warm today. I have reset all codes, and opened the breather holes in the grill cover. Any ideas if there is a common denominator with any of these? Where should I start?

Clear them if you can, that many codes is indicative of a gnd issue in most cases, not just the ones at battery, ones on block to frame and body to frame, remember these are computer controlled engines looking for correct voltage from sensor on said engine 0-5v range for many, any resistance in the circuit from corrosion on device path gnd and you will have signal error that causes the multi faults you are seeing.

truck runs good other than the codes ?????
