P2E1D: Drive Motor A Phase X Current Sensor Circuit Low

The current sensor for drive motor A phase X reports a circuit low fault. Phase current measurement is unreliable.

High severity. Can I keep driving?If the car still runs, drive as little as possible and go to a specialized repair shop. Do not touch the orange cables: they carry high voltage.

Symptoms

EV/hybrid system warning light on
Reduced motor power or torque
Possible limp mode or vehicle shutdown

Most likely causes

Current sensor failed
Wiring fault
Connector pins corroded - high contact resistance

What to check, in order

Start with the simplest. You can tick off each step.

Read the codes with a hybrid-compatible scanner and write down the freeze frame data
With the connector unplugged, check whether the signal wire is making contact with ground.
Make sure the battery cooling air intake is clean
Check the 12 V auxiliary battery, which can also trigger warnings
Leave any high-voltage measurements to a specialized repair shop

Good to know

Repair difficulty: hard
It can trigger limp mode.

What each character of P2E1D means

P: Powertrain: engine and transmission
2: Generic code: same on every make
E: Subsystem depends on the code range
1D: Specific fault in that system
