Hello, new on here from laredo tx. Currently having an issue, check engine and lightning bolt came on a couple days ago, truck runs fine no issues. I do have two codes P0642 and P0341 pop up. Truck has been deleted running an EZLYNK tuner, Def and DPF deleted, 5in turboback exhaust, s&b cold air intake, banks monster ram intake, arp headstuds.
2014 Ram 2500 6.7 4x4 Laramine Longhorn
How’s your voltage? How old are the batteries in the truck?
Service electronic control throttle light went away with the ezlynk firmware update. But now i just have a P0642 code pop up. Ive checked all the wiring and everything looks good.
Some info from another source:
"There are two "sensor 5V power supply" circuits in ECM, #1 and #2 .P0642 = #2 "sensor power supply" failure.So there will some sensors affected.Start looking for rubbing wiring between wiring/ground.According to my readings from forum there are two known locations to look at: wiring harness above the AC comp and a connector near the trans dip stick. May want to try to disconnect the fan clutch to see if all the other code go away.If YES then the fan clutch is the BAD boy"
