I was pulling a 13,700 lb. 5th wheel up a 5% grade at 50 mph and the coolant gauge went to 235+ degrees before the fan came on. It was night and 47 degrees outside. Check engine light came on but went off the next day with no trailer. Have not towed since. Code stayed in and is P2563 - Turbocharger Boost Control Postion Sensor - received reading out of range.

Anyone else had this? It is a 2006 LBZ with 151,000 miles. Any insight would be appreciated.

Thanks.
