P2072Throttle Actuator Control System - Ice Blockage (Bank 1)

  • Generic OBD-II code · Powertrain
  • Can trigger limp mode
How the car detects it
Not related to the tuning valve: P2072 belongs to the electronic throttle system. If the throttle plate cannot move freely in frost, the controller assumes ice and runs repeated open and close strokes to break it loose; the code records that event. Ford's 2012 OBD summary lists it for second-generation throttle control as a non-MIL fault, and Ford's 2014 code list marks it for the wrench lamp only. FCA bulletin 09-023-23 covers the 2013 to 2023 RAM 1500 with the 3.6L V6: P2072 together with P2110 and P2118, sometimes a no-start below freezing, caused by moisture from the crankcase ventilation freezing on the throttle blade. The fix is drying throttle body and PCV parts, a kit with new air cleaner lid and make-up air hose, plus an oil change. Speed may be limited meanwhile.
What you may notice
  • Wrench or engine light after a cold start in frost
  • Limited engine speed or reduced power
  • Engine may not start in deep frost
Likely causes
  • LikelyWater from the crankcase ventilation condensing and freezing at the throttle plate
  • PossibleFrequent short trips in frost leave water in the engine oil and breather
  • PossibleHeater of the breather line or throttle body (where fitted) not working
  • RareWater entering the air intake through a loose duct or wet air filter
