P0C5D 2018 Chevrolet Silverado Code - Drive Motor Position Sensor Circuit 2 High Voltage
Quick Answer
The generator control module also called the starter/generator control module, is comprised of the following three control modules: the hybrid/EV powertrain control module 1, 14 V power module, and the drive motor control module. Common causes include Faulty Starter/Generator, Starter/Generator harness is open or shorted, Starter/Generator circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0C5D 2018 Chevrolet Silverado Description
The generator control module monitors the angular position, speed, and direction of the starter generator rotor based upon the signals of the resolver-type motor 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 starter generator.
At ignition ON, an AC voltage, 10 kHz excitation signal is output to the drive coil. The drive coil excitation signal creates a magnetic field surrounding the two driven coils and the irregular-shaped rotor. The generator 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 generator control module to determine the exact position, speed, and direction of the starter generator rotor. The position sensor is a non-serviceable part of the starter generator.
The Diagnostic Trouble Code (DTC) will be set when the Drive Motor Position Sensor Circuit 2 reference voltage is greater than 4.9 V.

Frequently Asked Questions about P0C5D 2018 Chevrolet Silverado Code
1. What does the OBDII code P0C5D mean on a 2018 Chevrolet Silverado?
The P0C5D code indicates a "Drive Motor Position Sensor Circuit 2 High Voltage," meaning the vehicle's hybrid or electric motor position sensor circuit is detecting a voltage reading outside the specified range.
2. What are the common symptoms of the P0C5D code in a 2018 Chevrolet Silverado?
Common symptoms include reduced or no electric motor performance, illuminated check engine light, decreased fuel efficiency, and possible limited vehicle power mode.
3. What causes the P0C5D code to trigger?
The code can be caused by a faulty drive motor position sensor, damaged or corroded wiring, a short circuit, a poor electrical connection, or a malfunctioning hybrid powertrain control module.
4. Can I drive my 2018 Chevrolet Silverado with a P0C5D code?
Driving with this code is not recommended, as it may lead to further damage to the hybrid or electric motor system and could result in reduced performance or drivability issues.
5. How is the P0C5D code diagnosed?
A technician will use a scan tool to confirm the code, inspect the drive motor position sensor and its wiring, and check for any loose connections, shorts, or signs of corrosion.
6. How do you fix the P0C5D code on a 2018 Silverado?
Repairs may involve replacing the drive motor position sensor, repairing or replacing damaged wiring, addressing electrical connection issues, or reprogramming/updating the hybrid powertrain control module.
7. How much does it cost to repair the P0C5D code?
Repair costs can vary but typically range from $200 to $800, depending on whether the issue is with the sensor, wiring, or hybrid system components.
8. What tools are needed to fix the P0C5D code?
Common tools include a multimeter for voltage testing, a scan tool for diagnostics, and basic hand tools to access and replace the sensor or wiring.
9. Can a faulty drive motor position sensor damage other components?
Yes, if not addressed, it could lead to strain on the hybrid or electric motor system, potentially damaging other components like the inverter or powertrain control module.
10. Is the P0C5D code covered under warranty for a 2018 Chevrolet Silverado?
This depends on the vehicle's warranty coverage. If the issue is related to the hybrid system, it may be covered under the hybrid component warranty. Check with your dealer for specific details.
