since i removed the intake heater plug from the manifold i have been the 0543 code once in a while(looks to be low ihp amp draw), is there any ideas on what to do to elminate this occourance, will be needing in the winter months , so i must be able to go back to it then, thanks for the reply:(

You'll either need to keep clearing the code (stops setting when temps warm up to around 70°f or fashion a resistive load to the lead to show the ECM what it wants to see.

thanks jk, will find a load for it
