ohm testing isnt always accurate. especially with heaters. last one i had ohmed out fine. but failed live
I Agree on this, My Heater was very close to Ohm spec. Just slightly off but would not cycle. You can download Forscan on a PC and use a cheap OBD WIFI,Bluetooth or wired connector. You can control all the reductant stuff with it.
The one that was bad on my truck would not cycle on and the current would not budge. I then verified that the harness was good by disconnecting an watching all the other info flat line( tank level voltage, Reductant purge valve, ex..) Forscan is a good option for a lot of DIY service. Can't do it all but can do enough.
