Pinpoint Test N : P06A0: Notes
Refer to Manual 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. REFER to: Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System Operation and Component Description .
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. |
Possible Sources
- 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.
