Description
A/C REFRIGERANT PRESSURE SENSOR CIRCUIT


PCM uses input signal from A/C refrigerant pressure sensor to
determine if it should turn on engine coolant fans. When signal is out
of range, DTC P0530 sets and PCM will not allow A/C clutch to engage.

Symptoms
You likely won't notice any drivability problems.

Causes
  • A/C refrigerant pressure sensor signal less than 0.1 volt.
  • A/C refrigerant pressure sensor signal greater than
    4.9 volts.
Solutions
  • Check for open/short circuit in wiring harness.
  • Check for damaged connector.
  • Replace A/C refrigerant pressure sensor.
