P2E1E
Moderate Severity (Level 3)Drive Motor A Phase X Current Sensor Circuit High
P2E1E usually means drive Motor A Phase X Current Sensor Circuit High.
Can you still drive with P2E1E?
⚠️Short-distance driving is usually OK, but have this diagnosed within a week to prevent further damage.
Typical repair cost: $80 – $1200
Severity Level 3 — Moderate
This code indicates a moderate issue that may affect vehicle performance and fuel economy. Continued driving is possible in most cases, but prompt diagnosis and repair are recommended to prevent further damage.
Common Symptoms
- Check Engine Light illuminated
- Engine may run rich or have poor fuel economy (PCM sees faulty signal)
- Engine performance reading abnormally high or staying at maximum
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Failed engine sensor or actuator — internal short causing abnormally high voltage signal to the control module
- Wiring shorted to a 5V reference or 12V power wire in the same harness — wires melted together or chafing at a common point
- Poor ground connection for the powertrain/engine system — high resistance in ground path causes voltage to read high
- Faulty voltage regulator or power supply within the sensor
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($26-121 at shop, free at auto parts store for basic scan)
- Visually inspect the powertrain/engine system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $64 diagnostic fee at shop)
- Test engine sensor or actuator with a multimeter at the connector — compare readings to factory service manual specs. If out of spec, replace engine sensor or actuator ($80-1200)
- Check the reference voltage supply to engine sensor or actuator — should be steady 5V (or 12V) — if low, trace back to PCM/BCM voltage regulator ($115-511 if module repair needed)
- Perform a voltage drop test on the ground side of the powertrain/engine system circuit — more than 0.1V drop means a bad ground that must be cleaned/repaired ($62-253 at shop)
