P2C6DDrive Motor A Phase Y Current 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
- P2C6D is set when phase Y of drive motor A carries too little current while the inverter drives it, the typical signature of an open phase. No manufacturer documents P2C6D publicly. A test of this kind can run at start-up: on its 2019 power-split hybrids Ford checks the phase circuits right after power-up and declares a fault if less than 5 A flows during the 100 ms test. On a dual-winding motor of the kind shown in a Mitsubishi Electric patent, each winding set is driven separately, so an open Y lead in the second set does not affect U, V and W, but the machine loses torque and runs unevenly. Typical finds are a lifted or burnt terminal, a cracked busbar, a dead switching leg or an open winding. P2C6C is the general Y code, P2C6E the high side.
- What you may notice
- Hybrid or drive warning and MIL
- Noticeably weaker electric drive, vibration or humming under load
- Likely causes
- LikelyPhase Y lead, busbar or terminal open or high-resistance
- PossibleY switching leg of the inverter not conducting (switch or gate driver)
- PossiblePhase Y current sensor or its supply failed, reading near zero
- RareOpen phase Y winding inside the motor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
