The P0C52 fault code refers to the Drive Motor 1 Position Sensor Circuit 1 having low voltage.

This fault code is monitored by the motor control module, which keeps track of the angular position, speed, and direction of the drive motor rotor. It does this by analyzing the signals from a resolver-type position sensor. The position sensor consists of a drive coil, two driven coils, and a metallic rotor attached to the drive motor shaft.

When the vehicle is turned on, the motor control module sends a 7V AC, 10kHz excitation signal to the drive coil, creating a magnetic field around the driven coils and rotor. The module then monitors the return signals from the driven coils, known as Sine and Cosine waveforms. The size and shape of these return signals vary based on the position of the metallic rotor. By comparing the two driven coil signals, the motor control module can determine the exact position, speed, and direction of the drive motor rotor.

If the circuit voltage drops below 0.5V, the diagnostic trouble code (DTC) P0C52 will be set, indicating a low voltage issue in the Drive Motor 1 Position Sensor Circuit 1.

What are the possible causes for the automobile fault code p0c52?

If you’re seeing the engine light or service engine soon warning light on your dashboard, the fault code P0C52 could be the culprit. This code is often caused by a faulty drive motor 1 position sensor, an open or shorted sensor harness, a poor electrical connection in the sensor circuit, or a faulty power inverter module. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
