This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the sensor that tells it where the electric motor is. Because of this, the car might not drive as well as it should.
The P1E97 code is triggered when the vehicle's control module detects an issue with the position sensor of Drive Motor 'A', which may cause the vehicle to enter a 'limp home' mode to protect the system.
The drive motor position sensor monitors the position and rotational speed of the electric drive motor. If the sensor sends an incorrect or implausible signal, the control module may request a limp home mode to prevent damage to the motor or drivetrain.
• Reduced vehicle performance
• Warning light on the dashboard
• Vehicle may enter limp mode
• Faulty drive motor position sensor
• Wiring issues such as shorts or open circuits
• Faulty control module
Drive Motor: The electric motor that powers the vehicle.
Position Sensor: A device that detects the position of a component, such as a motor.
• Check for any additional trouble codes.
• Inspect the wiring and connectors for damage or corrosion.
• Test the drive motor position sensor for proper operation.
• Replace the faulty drive motor position sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Volt
• Chevrolet Bolt
• Cadillac ELR
• Regular maintenance and inspection of electrical components
• Avoiding exposure of the vehicle to extreme conditions
• Timely addressing of warning lights
Sensor Issue
• Do not ignore warning lights on the dashboard.
• Seek professional diagnostic services if unsure.
• Avoid driving the vehicle extensively until repaired.
Check with the vehicle manufacturer for warranty coverage on electric drive components.
This code has become more common with the increase in electric and hybrid vehicles, as they rely heavily on motor position sensors.
Moderate – The vehicle may still be drivable but with reduced performance.
Operating a vehicle in limp mode for extended periods can lead to further damage and potential safety risks.
• Vehicle in a safe, stationary position
• Engine off and key out of ignition
The drive motor position sensor is typically located within or near the electric drive motor assembly.
Q: Can I drive my car with a P1E97 code?
A: While you can drive the car, it may not perform well, and it's best to have it checked as soon as possible.
Q: What does 'limp home mode' mean?
A: Limp home mode is a safety feature that limits the vehicle's performance to prevent further damage.
