  1. Disconnect the connector from the A/C pressure sensor.

  1. Connect the three 1.5 V dry cell batteries' positive (+) lead to terminal 3 and the negative (-) lead to terminal 1.

  1. Connect the voltmeter's positive (+) lead to terminal 2 and the negative (-) lead to terminal 1.

  1. Measure the voltage according to the value(s) in the table below.

    Standard Voltage:
    Tester Connection
    		Condition
    		Specified Condition
    2 (PR) - 1 (-)
    		Refrigerant pressure:
    0.39 to 3.187 MPa (57 to 463 psi)
    		1.0 to 4.8 V
    If the voltage is not as specified, replace the A/C pressure sensor.
