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 air fuel module IAFM, and remove oil or water near the fresh air port as needed.
- Disconnect the tube at the camshaft cover and check the tube for ice obstruction. Repair as needed.
- 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.
