P2EABActive Radiator Air Flow Control Module A Over Temperature

  • Generic OBD-II code · Powertrain
  • Turns on the check-engine light
  • Matters for the ITP
  • Needs a drive cycle to confirm a fix
How the car detects it
P2EAB means module A of the active radiator air flow system reports that its own electronics have overheated. Such smart actuators carry their motor driver on board and protect it: J2012 records the matching case for the grille shutter as P05C0, where the actuator switches its output stage off when the chip runs too hot. Typical triggers are a motor straining against ice, dirt or a jammed linkage, a mounting place close to the radiator in hot weather, or an internal fault. Hyundai and Kia's patent US11225900 shows where such modules sit, directly between bumper opening and radiator. No manufacturer documents P2EAB publicly. While the module is off, the flaps remain where they stopped; if they stay closed under load the engine can run hotter, otherwise fuel use and warm-up suffer.
What you may notice
  • Check engine lamp on, where the maker assigns a MIL
  • Flaps stop moving for a while
  • Higher coolant temperature under load if the flaps are stuck closed
Likely causes
  • LikelyFlaps blocked by ice, dirt or a damaged linkage, motor overloaded
  • PossibleHigh heat at the mounting place near the radiator
  • PossibleInternal fault in the module or its temperature sensing
Inspection (ITP)
Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
Repair
Medium · Often possible to do yourself.Typical cost: €0 – €600
