A/C Pressure Transducer
A/C PRESSURE TRANSDUCERNOTE: It is not necessary to recover the refrigerant before removing the A/C pressure transducer.
The A/C pressure transducer is used by the PCM to monitor the discharge pressure in the high-pressure side of the refrigerant system. The PCM monitors the A/C pressure transducer through the ACP circuit. When the A/C pressure transducer is reading a discharge pressure above acceptable levels, the PCM will disengage the A/C compressor clutch.
