WARNING: This page is about a different car, the 2016 Ford Transit Connect. However, it is still accessible from the selected car via links, so may be relevant.
Refer to Electronic Engine Controls - 1.6L GTDI Sigma 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
