A/C Compressor: TD4
TD4 vehicles are fitted with a Visteon VS16 variable displacement A/C compressor. Displacement is controlled internally by a control valve, which is integral with the compressor. The control valve measures the input and output pressures of the refrigerant entering and leaving the compressor and controls the angle of the internal swash plate accordingly.
NOTE:
There is no external control over A/C compressor swash plate angle. Consequently, compressor displacement is neither measured nor calculated by any external control component.
Compressor clutch engagement is controlled by the ECM. See CONTROL COMPONENTS .
