P2EC1 is set when the compressor outlet temperature sensor delivers a voltage above its permitted window. Because the module feeds the sensor through a pull-up resistor, any break in the current path lifts the input to the reference: an unplugged or corroded connector, a cracked wire or a burnt-out element. A short to 5 V or battery voltage has the same effect. For an NTC thermistor this shows up as severe cold, for a PTC part as severe heat. No manufacturer documents the code publicly. The outlet sensor works in a harsh spot, where charge air can reach about 200 °C, a value Ford's diesel charge air cooler check still covers, so heat and vibration at the plug are a known strain. Low reading: P2EC0; general fault: P2EA6.

Likely causes

Connector unplugged, corroded or with spread terminals
Signal or ground wire broken
Sensor element open circuit
Signal shorted to 5 V reference or battery voltage

Symptoms

  • Check engine lamp on
  • Live data shows a fixed extreme value
  • Usually no noticeable change in driving
