P0EA2DC/DC Converter Current Sensor C Circuit Low
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0EA2 is stored when current sensor C of a DC/DC converter reports a raw value under its lower limit. Because current sensors in these units normally place their zero-current output at mid-supply, a value near zero volts rarely means low current; it points to a ground short, a lost sensor supply or a broken signal path. No manufacturer documents P0EA2 publicly. The closest published case is Porsche's P0E9D00 on the B channel of the Taycan converter, a short to ground that in fact came from a monitoring threshold set too low and was cured with new software. Ford rates current inputs as faulty below 4.5 V raw. CARB asks for out-of-range checks of such inputs. The high fault of sensor C is P0EA3.
- What you may notice
- Warning lamp and possibly a stop request
- Converter switched off or derated
- 12 V battery discharges while driving
- Likely causes
- LikelySensor C signal shorted to ground
- PossibleMissing supply voltage of the current sensor
- RareMonitoring threshold in the software set too tight
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
