P0533 Isuzu Code - A/C Refrigerant Pressure Sensor Circuit High Input
Quick Answer
The Powertrain Control Module (PCM) monitors the high side refrigerant pressure via a A/C refrigerant pressure sensor. Common causes include A/C system low or over charge with refrigerant, Faulty A/C refrigerant pressure sensor, Cooling fans in-operative. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
