P0C5D 2016 GMC Sierra 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 2016 GMC Sierra 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 2016 GMC Sierra Code
1. What does the OBDII code P0C5D mean for a 2016 GMC Sierra?
The P0C5D code indicates a high voltage issue in Drive Motor Position Sensor Circuit 2, which monitors the position of the drive motor in the hybrid or electric system.
2. What are the common symptoms of a P0C5D code in a 2016 GMC Sierra?
Symptoms may include reduced power mode, illuminated check engine light, erratic transmission shifts, or decreased vehicle performance.
3. What causes the P0C5D code to appear in a 2016 GMC Sierra?
Possible causes include a faulty drive motor position sensor, damaged wiring or connectors in Circuit 2, or a malfunctioning control module.
4. Can I drive my 2016 GMC Sierra with a P0C5D code?
While the vehicle may still be drivable, it’s not recommended as the issue could lead to further damage or reduced performance, especially in hybrid or electric components.
5. How do you diagnose the P0C5D code in a 2016 GMC Sierra?
Diagnosis typically involves using a scan tool to read the code, inspecting the sensor and associated wiring for damage, and testing the voltage in Circuit 2.
6. What repairs are needed to fix the P0C5D code?
Repairs may include replacing the drive motor position sensor, repairing or replacing damaged wiring or connectors, or reprogramming the control module if needed.
7. How much does it cost to fix the P0C5D code on a 2016 GMC Sierra?
Repair costs vary depending on the exact issue but can range from $150 to $500 for parts and labor, depending on whether the sensor or wiring needs replacement.
8. Can a bad drive motor position sensor cause long-term damage?
Yes, ignoring the issue can lead to further damage to the hybrid or electric drive system and potentially result in higher repair costs.
9. What tools are needed to troubleshoot the P0C5D code?
You’ll need an OBDII scanner, a multimeter for voltage testing, and potentially a wiring diagram for the vehicle’s drive motor circuit.
10. Is the P0C5D code unique to the 2016 GMC Sierra?
No, this code can appear in other vehicles with hybrid or electric drive systems, but the specific diagnosis and repair steps may vary by make and model.
