This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks there's a problem with a sensor that tells it where a part of the electric motor is. It's like if a video game controller couldn't tell where the joystick is pointing.
The P0C58 code indicates that the voltage signal from the position sensor for Drive Motor B is higher than expected, which can affect the motor's performance.
The Drive Motor B Position Sensor is responsible for monitoring the position of the motor's rotor. The sensor sends a voltage signal to the Powertrain Control Module (PCM) or Motor Control Module (MCM), which uses this information to control the motor's operation. A 'Circuit A High' condition means the sensor is sending a voltage higher than the normal operating range.
• Reduced vehicle performance
• Illuminated Check Engine Light
• Possible electric motor malfunction
• Faulty Drive Motor B Position Sensor
• Wiring issues such as open or short circuits
• Faulty PCM or MCM
PCM: Powertrain Control Module
MCM: Motor Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for the position sensor.
• Test the sensor's voltage and resistance.
• Check the PCM or MCM for faults.
• Replace the Drive Motor B Position Sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Update or replace the PCM or MCM if necessary.
• OBD-II scanner
• Multimeter
• Wiring diagram

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure wiring is secure and intact
• Use OEM parts for repairs
Sensor Issue
• Avoid driving the vehicle until the issue is resolved.
• Consult with a professional mechanic for accurate diagnosis.
Check with the vehicle manufacturer for specific warranty details related to the powertrain or hybrid system.
This code is commonly associated with hybrid and electric vehicles, reflecting the importance of precise motor control.
Moderate – The vehicle may still operate, but performance could be compromised.
Ignoring this issue could lead to further damage to the vehicle's electric motor system.
• Vehicle must be in a safe, stationary position.
• Ensure the battery is fully charged.
The Drive Motor B Position Sensor is typically located near or on the electric motor housing.
Q: Can I drive with a P0C58 code?
A: It's not recommended as it may lead to reduced performance or further damage.
Q: How can I reset the P0C58 code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is fixed first.
