P2EC1Turbocharger Compressor Outlet Temperature Sensor Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- 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.
- What you may notice
- Check engine lamp on
- Live data shows a fixed extreme value
- Usually no noticeable change in driving
- Likely causes
- LikelyConnector unplugged, corroded or with spread terminals
- PossibleSignal or ground wire broken
- PossibleSensor element open circuit
- RareSignal shorted to 5 V reference or battery voltage
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €40 – €300
