Pinpoint Test S : P06A0: Notes
Refer to Manual Climate Control System for schematic and connector information.
Normal Operation and Fault Conditions
The Externally Controlled Variable Displacement Compressor (EVDC) is electronically controlled by the PCM. The PCM pulse width modulates the ground to the Externally Controlled Variable Displacement Compressor (EVDC) solenoid to change the A/C compressor displacement.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P06A0 | Variable A/C Compressor Control Circuit | This DTC sets when the PCM senses greater than expected voltage on the sensor feedback circuit, indicating a short to voltage or an open circuit or an open sensor. |
Possible Sources
- Fuses
- Wiring, terminals or connectors
- A/C compressor
- PCM
Visual Inspection and Diagnostic Pre-checks
- Inspect for loose or corroded PCM and A/C compressor connections.
- Make sure BJB fuse 27 (15A) is OK.
