This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with a sensor that helps control one of the electric motors. It's like the sensor isn't set up right, and the car is confused about where the motor is or what it's doing.
The P1E46 code indicates that the position sensor for Drive Motor 'B' is not configured correctly, causing the control module to receive inaccurate data.
The Drive Motor 'B' Control Module relies on a position sensor to determine the motor's position and movement. If the sensor is not configured properly, the module cannot accurately control the motor, leading to performance issues.
• Reduced vehicle performance
• Warning light on the dashboard
• Unusual noises from the motor
• Faulty position sensor
• Incorrect sensor calibration
• Wiring issues or poor connections
OBD-II: On-Board Diagnostics, a standardized system in vehicles for self-diagnosis and reporting.
Calibration: The process of adjusting the sensor to ensure accurate readings.
• Check for any loose or damaged wiring to the sensor.
• Verify the sensor's calibration settings.
• Use a diagnostic tool to read sensor data and confirm operation.
• Recalibrate the position sensor.
• Repair or replace faulty wiring.
• Replace the position sensor if defective.
• OBD-II scanner
• Multimeter
• Calibration tool

Moderate
• Chevrolet Volt
• Chevrolet Bolt
• Cadillac ELR
• Regular maintenance checks
• Ensure proper calibration of sensors
• Inspect wiring for wear and tear
Sensor Issue
• Avoid driving at high speeds until fixed.
• Schedule a service appointment promptly.
Check with the vehicle manufacturer for warranty coverage on electric motor components.
This code is more common in hybrid and electric vehicles due to their reliance on electric drive motors.
Moderate – While the vehicle may still be drivable, performance could be affected, and further damage may occur if not addressed.
Driving with a malfunctioning motor control system can lead to reduced performance and safety issues.
• Vehicle in 'Park' or 'Neutral'
• Engine running
The position sensor is typically located near Drive Motor 'B', which is part of the vehicle's electric drive system.
Q: Can I drive with a P1E46 code?
A: It's possible to drive short distances, but it's not recommended due to potential performance issues.
Q: How do I reset the P1E46 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
