This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble reading the position of one of the electric motors. It's like when your video game controller doesn't work right because the joystick is acting funny.
The P0C59 code is triggered when the vehicle's powertrain control module (PCM) detects an intermittent or erratic signal from the position sensor associated with Drive Motor B.
Drive Motor B Position Sensor Circuit A is responsible for providing the PCM with accurate data regarding the position of Drive Motor B. An intermittent or erratic signal can cause the PCM to misinterpret the motor's position, potentially affecting vehicle performance.
• Check Engine Light illuminated
• Reduced vehicle performance
• Unusual noises from the motor area
• Faulty Drive Motor B position sensor
• Damaged or corroded wiring/connectors
• Faulty PCM or software issue
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the Drive Motor B position sensor for proper operation.
• Replace the Drive Motor B position sensor if faulty.
• Repair or replace damaged wiring/connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance and inspections
• Ensure connectors are clean and secure
• Update vehicle software as recommended
Sensor Issue
• Avoid heavy acceleration until the issue is resolved.
• Consult a professional mechanic for accurate diagnosis.
Check with your vehicle manufacturer for warranty coverage on the powertrain and associated sensors.
This code has been more prevalent in hybrid and electric vehicles due to their reliance on electric drive motors.
Moderate – It should be addressed soon to prevent potential drivability issues.
Driving with this code may lead to reduced vehicle performance and should be addressed to ensure safety.
• Vehicle at operating temperature
• Drive motor engaged
The Drive Motor B position sensor is typically located near the electric motor assembly in the vehicle's drivetrain.
Q: Can I drive with a P0C59 code?
A: It's possible, but not recommended as it may affect vehicle performance.
Q: How do I reset the P0C59 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it shouldn't return.
