1. INSPECT A/C PRESSURE SENSOR

(a) Install the manifold gauge set.

(b) Disconnect the connector from the A/C pressure sensor.





(c) Connect three 1.5 V dry cell battery positive (+) lead to terminal 3 and a negative (-) lead to terminal 1.

(d) Connect a voltmeter positive (+) lead to terminal 2 and a negative (-) lead to terminal 1.

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

Standard Voltage:





If the voltage is not as specified, replace the liquid tube sub-assembly (A/C pressure sensor).
