Nitro 2WD V6-4.0L (2007)
Refrigerant Pressure Sensor / Switch: Testing and Inspection
A/C PRESSURE TRANSDUCER
The A/C pressure transducer is tested using a scan too. Before testing the A/C pressure transducer, be certain that the transducer wire harness connection
is clean of corrosion and properly connected. For the A/C to operate, an A/C pressure transducer voltage reading between 0.451 and 4.519 volts is
required. Voltages outside this range indicate a low or high refrigerant system pressure condition to the powertrain control module (PCM). The PCM is
programmed to respond to a low or high refrigerant system pressure by suppressing operation of the A/C compressor. Refer to the A/C Pressure
Transducer Voltage chart for the possible conditions indicated by the transducer voltage reading.
