P0C52 2018 Chevrolet Silverado Code - Drive Motor Position Sensor Circuit 1 Low 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 P0C52 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 1 reference voltage is less than 0.1 V.
What are the Possible Causes of the DTC P0C52 2018 Chevrolet Silverado?
- Faulty Starter/Generator

What are the common symptoms of the P0C52 code?
Common symptoms include reduced vehicle performance, illumination of the check engine light, poor acceleration, and possible hybrid system malfunction warnings.
What causes the P0C52 code on a 2018 Chevrolet Silverado?
Potential causes include a faulty drive motor position sensor, damaged wiring or connectors, low system voltage, or issues with the hybrid control module.
How can I diagnose the P0C52 code?
Start by checking the wiring and connectors for damage or corrosion, test the drive motor position sensor for proper operation, and verify the voltage supply to the circuit.
Can I drive my 2018 Silverado with the P0C52 code active?
Driving with this code is not recommended, as it may lead to reduced performance or damage to the hybrid or electric drive system.
How do I fix the P0C52 code?
Repairs may include replacing the drive motor position sensor, repairing damaged wiring or connectors, or updating/reprogramming the hybrid control module.
How much does it cost to repair the P0C52 code?
Repair costs vary, but replacing the drive motor position sensor typically ranges from $200 to $500, depending on parts and labor rates.
Can a dead battery trigger the P0C52 code?
A weak or dead battery can potentially cause this code if it leads to low voltage in the drive motor position sensor circuit.
Does the P0C52 code require a software update?
In some cases, a software update for the hybrid control module may be necessary to resolve the issue after physical repairs are completed.
What tools are needed to diagnose the P0C52 code?
You’ll need an OBDII scanner capable of reading hybrid system codes, a multimeter for voltage testing, and possibly a wiring diagram for the vehicle.
