This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the sensor that measures how hot the electric motor is, is saying it's way too hot, even though it might not be.
The P1B6C code is triggered when the temperature sensor for the drive motor 'A' reports a temperature reading that is higher than expected or plausible.
The drive motor 'A' temperature sensor is responsible for monitoring the temperature of the electric drive motor. If the sensor reports a temperature that is implausibly high, it could indicate a fault in the sensor circuit, a wiring issue, or a problem with the sensor itself.
• Check Engine Light is on
• Reduced vehicle performance
• Possible overheating warning
• Faulty drive motor temperature sensor
• Wiring issues or poor connections
• Faulty control module
OBD-II: On-Board Diagnostics, a standardized system for vehicle self-diagnosis and reporting.
Drive Motor: An electric motor that powers the vehicle's wheels.
• Use a diagnostic scanner to confirm the code
• Inspect the wiring and connections to the temperature sensor
• Test the temperature sensor for proper operation
• Replace the faulty temperature sensor
• Repair or replace damaged wiring or connectors
• Update or replace the control module if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Volt
• Nissan Leaf
• Toyota Prius
• Regular maintenance checks
• Ensure proper cooling system operation
• Avoid overloading the vehicle
Sensor Issue
• Do not ignore the warning light
• Have the vehicle inspected by a professional
• Avoid driving the vehicle if overheating is suspected
Check with the manufacturer for warranty coverage on sensors and related components.
This code has been reported in hybrid and electric vehicles where motor temperature monitoring is critical.
Moderate – It should be addressed soon to avoid potential motor damage.
Ignoring this code could lead to motor damage and reduced vehicle safety.
• Vehicle at operating temperature
• Drive motor active
The drive motor temperature sensor is typically located near the electric motor, often integrated into the motor assembly.
Q: Can I drive with a P1B6C code?
A: It's not recommended as it could lead to motor damage if the temperature is truly high.
Q: How do I reset the P1B6C code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
