Code P0C5D Cadillac Description

The drive motor position sensor is monitored by the motor control module. The motor control module monitors the angular position, speed, and direction of the drive motor 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. At vehicle ON, the motor control module outputs a 7 V 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 return signals, often referred to as Sine and Cosine waveforms, abbreviated SIN and COS. 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 coil signals allows the motor control module to determine the exact position, speed, and direction of the drive motor rotor. The drive motor 1 position sensor is serviceable separately from the drive motor assembly. The Diagnostic Trouble Code (DTC) will be set when the circuit voltage is greater than 4.5 V.
