Fuel Bowl Heater element

Is the "on" time of the element controlled by the pcm or is it on all the time? If the pcm controls it, what sensors are involved in telling the pcm to do so?

Re: Fuel Bowl Heater element

The PCM tells it to come on when it's cold out. I would assume it shuts it off when oil temp comes up because the engine is now warming the fuel bowl up.

The factory EVTM book says that it gets power directly from fuse 22 which powers the pcm. It also says that it has an internal thermostat that controls the operation. I think the pads on the element are the regulator for in it. In the past those were described as thermistors that vary in resistance depending on the temperature.

Re: Fuel Bowl Heater element

Well since the pcm does not control it, anybody know where I can get a t-stat somthing like a disc style, but weather proof? I found some by thermodisc, but they appear to be made to order, not in stock. I am worried about my dahl filter gelling up and I would like to do something automatic.

Try sniffing around the veggie diesel sites. The make thermostats for heat tapes and stuff that are pretty cheap if you can find one that is ok appearance wise.
