P241C Throttle Actuator Control System - Ice Blockage (Bank 2)

P241C is the bank 2 counterpart of P2072 and only makes sense on engines that use a separate electronic throttle per bank. The controller records that the throttle plate of that bank was frozen in place, recognised by a blade that will not follow its command in cold weather. No manufacturer publishes P241C. For bank 1, Ford's 2012 OBD summary lists ice blockage for its second-generation throttle control as a non-MIL fault, while FCA bulletin 09-023-23 (2013-2023 RAM 1500, 3.6L V6) reports P2072 with a MIL, forced limited rpm and no-start in frost, caused by moisture from crankcase ventilation freezing on the blade. Expect reduced power or a no-start until the throttle body thaws.

Likely causes

Condensate from crankcase ventilation freezing on the throttle blade
Water or snow drawn into the intake tract
Damaged or poorly routed ventilation or make-up air hose

Symptoms

  • Reduced power or capped engine speed in frost
  • Engine will not start after a cold night
  • Warning lamp depending on manufacturer
