Pinpoint Test Y : DTC P06A0: Notes
Diagnostic Overview
Refer to Automatic Climate Control System for schematic and connector information.
Normal Operation and Fault Conditions
The externally controlled variable displacement compressor is electronically controlled by the PCM. The PCM pulse width modulates the ground to the externally controlled variable displacement compressor to change the displacement of the A/C compressor.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P06A0 | Variable A/C Compressor Control Circuit | The PCM senses greater than expected voltage on the sensor feedback circuit, indicating a short to voltage or an open circuit or sensor. |
