Yesterday I was pulling a pretty good load up a long hill and noticed that on my pulse monitor that when the engine temp hit 205 it went blank. So later down the road I came to another hill and laid into it to get the temp up to see what it would do and as soon as I hit 205 it went to 0 again. As soon as I let off and the temp dropped to 204 it came back on Anyone have any ideas?

 

Same thing happens with my EJWA. Something in the units can not process the signal when it get that high. The EJWA only goes to 200 for engine temp, then does not read anymore.

"* Note – Because of limitations on the stock computer systems on these trucks,
monitor will only display up to 200° Engine Coolant Temp (ECT)." From my Edge Manual.

 

Thanks Didn't realize that with the EJWA, must be the same thing with the adrenaline too. I just happen to have the engine temp on the screen yesterday and it was the first time I had noticed it.
