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.
