This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading the sensor that checks the electric motor's power. It's like trying to read a book with missing pages.
The P2E1C code indicates an issue with the circuit that measures the current in one phase of the electric drive motor, suggesting a range or performance problem.
The P2E1C code is set when the Powertrain Control Module (PCM) detects an abnormal signal from the current sensor circuit of Drive Motor A Phase X. This could be due to a range or performance issue, meaning the sensor is not reading within expected parameters.
• Check Engine Light is on
• Reduced power or performance
• Unusual noises from the motor
• Faulty current sensor
• Wiring issues or poor connections
• Malfunctioning Powertrain Control Module (PCM)
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use a scan tool to verify the code
• Inspect wiring and connections to the current sensor
• Test the current sensor for proper operation
• Replace or repair faulty wiring
• Replace the current sensor
• Reprogram or replace the PCM if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Volt
• Nissan Leaf
• Tesla Model S
• Regular maintenance checks
• Ensure wiring connections are secure
• Avoid overloading the electric motor
Sensor Issue
• Do not ignore the Check Engine Light
• Have a professional diagnose the issue
• Avoid driving the vehicle until repaired
Check with your vehicle manufacturer for warranty coverage on electric drive components.
This code has been more prevalent with the increase in electric and hybrid vehicles, as they rely heavily on electric motor sensors.
Moderate – It should be addressed soon to prevent further issues.
Driving with this code may lead to reduced performance or potential motor damage. Always follow safety guidelines.
• Vehicle in 'ON' position
• Motor running
The current sensor is typically located near the drive motor or integrated within the motor controller.
Q: Can I drive my car with a P2E1C code?
A: It's not recommended as it may lead to reduced performance or further damage.
Q: How do I reset the P2E1C code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
