P2072 - PCM IS INDICATING THE THROTTLE MODE HAS BEEN ACTIVATED

Description:	This DTC only identifies that the strategy has performed several open and closed cycles to remove potential ice build up. The DTC does not imply any system fault, only that the mode has occurred, and that mode may be causing a long start time.
Possible Causes:	Ice or oil in the induction system could be the result of a fault in the PCV system.
Diagnostic Aids:	CHECK the PCV system for evidence of water or ice: Disconnect the air induction fresh air plenum from the throttle body. Check for water or oily residue at the PCV fresh air port. Disconnect the tube at the camshaft cover and check the tube for ice obstruction/ice. Start the engine and, to check the PCV system, place a piece of card board on the crankcase vent in the rocker cover. If the cardboard is held on the crankcase vent and fumes are not exiting, reconnect the tube to the camshaft cover and the Air Induction port. If the test passes, no further investigation of the PCV system is required. If the cardboard is not held in place, turn off the engine and check the PCV valve side of the system for ice or obstruction and repair as needed. If no obstruction is found there, isolate and repair any obstruction in the intake manifold connection. If no obstruction is found there, make sure the PCV coolant heater is functional and repair as needed. If no fault is detected, make sure the PCV valve is allowing the proper vacuum flow and repair as needed.
