P0ED7Generator Phase Y Current
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P0ED7 is the general current code for phase Y, the middle phase of the generator's X-Y-Z set. Without being narrowed to low (P0ED8) or high (P0ED9), it says that the Y current no longer behaves as the inverter controller expects. No manufacturer documents P0ED7 publicly, and it is not known which production machines label their phases X, Y and Z. Ford describes what phase currents are used for in its 2019 hybrids: sensors on each phase feed the motor/generator control unit, which needs them to work out current magnitude and angle and also to confirm that the three AC cables are connected the right way. Monitoring of such electric drive parts is mandatory under CARB. Check the high-voltage connectors and look for other phase codes. Phase X: P0ED4, phase Z: P0EDA.
