conditioning when it is not pumping out cold air through the vents in your car.
Most cars have a warning light on the instrument panel that alerts when the
refrigerant level is low, while others rely on codes sent through the car's
on-board diagnostic generation 2 (OBD 2) system. If your car was produced
before 1995, then it may use R12 refrigerant, which is no longer being produced
now. But, you can have a mechanic update your older A/C system so you can use
an R134a recharge kit,
which can be bought at any car parts supply store.
You'll Need OBD 2 scanner for this job.
Find out the OBD 2 port on your car first.
The OBD 2 port on your car is located near the steering column, it generally will
be within 2 feet of the steering column and concealed behind a small panel that
can be removed easily by hand. The OBD 2 port is a 16-pin connector. Every car
manufactured after 1996 is equipped with this on-board computer (OBD 2).
Insert the scanner into the OBD 2 port and
turn the ignition key to the "Accessories" position. Power on the OBD
2 scanner on and wait it for several seconds to read the error codes from the
engine control unit (ECU).
Consult the error codes reported by the OBD
2 scanner by using a computer with Internet access to browse a table of error
codes. Other websites such as AutoZone also list this information in the online
repair guide for the make and model of your car. The OBD 2 code will show
whether the A/C refrigerant pressure sensor is faulty or the refrigerant only
needs recharging. If you are about to replace the sensor yourself, keeping in
mind that the OBD 2 code does not necessarily indicate whether the sensor or
the circuitry is causing the error which activated the "Check Engine"
light.
Use a multimeter to check the terminals on
the electrical connection leading to the A/C refrigerant pressure sensor. Disconnect
the electrical connector leading to the sensor. With the ignition key turned on
to the "Accessories" position, touch the probes to the terminals
leading from the car's electrical harness. If the multimeter does not register
any voltage coming from the terminals, it means your car's electrical system
needs to be repaired, but not the sensor. If you are interested in OBD 2
scanner, I am glad to communicate with you.
