Code P0C58 Chevrolet Description

The drive motor generator position sensor is monitored by the motor control module. The motor control module monitors the angular position, speed and direction of the drive motor generator rotor based upon the signals of the resolver-type position sensor. The position sensor contains a drive coil, two driven coils and an irregular shaped metallic rotor. The metallic rotor is mechanically attached to the shaft of the drive motor generator. At vehicle ON, the motor control module outputs a 7 volt ac, 10 kHz excitation signal to the drive coil. The drive coil excitation signal creates a magnetic field surrounding the two driven coils and the irregular shaped rotor. The motor control module then monitors the two driven coil circuits for a return signal. The position of the irregular metallic rotor causes the magnetically-induced return signals of the driven coils to vary in size and shape. A comparison of the two driven coils signals allows the motor control module to determine the exact position, speed and direction of the drive motor generator rotor. The position sensor is a non-serviceable part of the drive motor generator.

Frequently Asked Questions about P0C58 Chevrolet Code

1. What does the OBDII code P0C58 mean on a Chevrolet?

The P0C58 code indicates a "Drive Motor 2 Position Sensor Circuit 1 High Voltage," meaning the voltage in the circuit for the second drive motor's position sensor is higher than expected.

2. What are the symptoms of the P0C58 code on a Chevrolet?

Symptoms may include reduced engine or hybrid system performance, a Check Engine Light, difficulty accelerating, or the vehicle entering "limp mode."

3. What causes the P0C58 code to appear on a Chevrolet?

Common causes include a faulty drive motor position sensor, damaged wiring or connectors in the circuit, or an issue with the hybrid/EV control module.

4. Can I drive my Chevrolet with a P0C58 code?

It is possible to drive the vehicle, but it is not recommended as it could compromise performance or lead to further damage in the hybrid/EV system.

5. How do you diagnose the P0C58 code on a Chevrolet?

Diagnosis involves scanning for codes, inspecting the motor position sensor and related wiring, testing circuit voltages, and checking the hybrid/EV control module for faults.

6. How do you fix the P0C58 code on a Chevrolet?

Repairs may include replacing the drive motor position sensor, repairing damaged wiring or connectors, or reprogramming/updating the hybrid control module if needed.

7. What tools are needed to diagnose the P0C58 code?

You will need an OBDII scanner capable of reading hybrid system codes, a multimeter for voltage testing, and possibly a factory service manual for detailed wiring diagrams.

8. How much does it cost to fix the P0C58 code on a Chevrolet?

Costs vary, but sensor replacement typically ranges from $200 to $500, while wiring repairs or control module replacements could cost more depending on labor and parts.

9. Can a bad battery cause the P0C58 code on a Chevrolet?

While unlikely, a failing high-voltage battery can indirectly affect the hybrid system and sensors, so itâ€™s worth checking the battery if other components seem functional.

10. Does the P0C58 code require reprogramming the control module?

In some cases, reprogramming or updating the hybrid/EV control module software may be necessary if the issue is software-related rather than a hardware fault.
