Expansion Block/Orifice Tube: Description and Operation
A/C Pressure Transducer
Air Conditioning
A/C Pressure Transducer (Non-Hybrid Only)
The A/C pressure transducer monitors the compressor discharge pressure and communicates with the PCM. The PCM will interrupt A/C compressor
operation in the event that the A/C pressure transducer indicates high system discharge pressures. It is also used to sense low charge conditions. If the
pressure is below a predetermined value for a given ambient temperature, the PCM will not allow the clutch to engage.
The A/C pressure transducer is located on the receiver/drier. It is not necessary to recover the refrigerant before removing the A/C pressure transducer.
