PO542 code

[DGerth]

Gentlemen,

Have had this code thrown 3 separate times, charge air heater circuit A high, on a 2013 3500, 6.7,aisin auto with 60K miles. Not sure if the heater is bad or what. Appears to cycle ok when it's cool enough. Have cleaned all connections to heater, all are tight. What could be the problem? Any suggestions , solutions?
tks

Mine has done that as well. Replaced the solonoid by the right side battery and made sure the connections were clean and tight.
