P2E1FDrive Motor A Phase Y Current Sensor Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2E1F stands for a circuit fault of the phase Y current sensor of drive motor A that is not sorted into a low or high case. No manufacturer documents P2E1F publicly, and even the U/V/W equivalents of this general code see little use: GM's 2013 to 2019 hybrid tables cover the phase sensors with offset, low, high and sum checks only, while Ford's 2019 hybrid summary says that current sensor faults of its motor inverter end up in the phase current codes P0A5D, P0A60 and P0A63 or in P0BFD. Which code a car stores for the same defect thus depends on the maker. Y is the middle phase of the second winding group; a Mitsubishi Electric patent gives each of X, Y and Z its own sensor. Check the inverter's low-voltage connector and supply first. Range check: P2E20; low and high: P2E21, P2E22.
- What you may notice
- Hybrid warning lamp and MIL
- Electric drive limited or switched off
- Other phase current codes may be stored as well
- Likely causes
- LikelyPhase Y current sensor in the inverter failed
- PossiblePoor contact at the inverter's low-voltage connector
- PossibleSensor supply or ground interrupted
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
