cooling fans staying on
Got a 2008 6.4l in the shop that has the cooling fans staying on all the time. If you unplug them they shut off so clutch is working. Got it on the scanner and the only fault I found was the transmission over temperature lockup had a fault in the pid's. Would this cause the fans to run all the time? If so what is this fault? is it a sensor or the temperature sensor reading wrong? the temp sensor shows good tranny temp so not sure. PLEASE HELP!!! This truck is annoying!!!
