P1462 - FAULT CODE - OBD2

P1462 FORD, LINCOLN, MAZDA, MERCURY: AIR CONDITIONING PRESSURE SENSOR LOW CIRCUIT

The air conditioning system is part of the comfort provided to the vehicle occupants. Its purpose is primarily to cool the interior of the car, ensuring a cooler and more comfortable ride. It should be noted that the vehicle air conditioning system does not generate cold air in the vehicle, like other types of air conditioning systems, it cools the air that is already in the car, it does not produce it.

For a good operation of the air conditioner, there are many components involved in its testing. One of these is the air conditioning pressure sensor, which is located on the high and low sides of the system. This safety element controls the refrigerant pressure on their respective side of the system. With the monitoring of this, various failures that may experience the air conditioner, which in turn affect the compressor are sought.

The P1462 OBDII diagnostic code is set on Ford, Lincoln, Mazda, and Mercury vehicles when there is an erratic operation of the air conditioning pressure sensor, where the air conditioning circuit has voltages below the allowable levels.

• Check Engine lamp illuminated.
• The air conditioning system turns off and on quickly.
• The AC system fails to cool the vehicle.
• The air conditioning compressor does not work.

DTC P1462 OBD2 is set for one of the following reasons:

• Air Conditioning Pressure Sensor wires may have been damaged.
• Air Conditioning Pressure Sensor circuit may have deficiencies resulting in an open circuit.
• The Air Conditioning Pressure Sensor may be faulty.
