Engine Hot A/c Turned Off Need A Fix

[marcel08gmc]

hey guys, i recently got a espar coolant heater installed in my 08 gmc sierra 1500 gas and after running the heater when it was cold i went out to start the truck and in the DIC read "engine hot a/c turned off". the truck still started and ran fine but, the temp gauge showed no tempature and the DIC still read the samething. the next day i didn't use the espar coolant heater and everthing is normally temp gauge worked perfect and no message in the DIC, so i phone the company that installed it for me and he said to bring it to gm and get the perameters moved higher on the coolant temp sensor so i did, went to gm and they told me that they can't do that, but i took it as they have no clue how to do it lol. does anyone no how to get around this problem????????

thanks marcel

There have been some posts on here about engines throwing codes after using block heaters. I know the GM heaters don't even kick until 0 F.

 

Here's a search looking for block heater posts. Read through them. I think you'll find your answer. Someone with a tuner can probably adjust it for you
