A/C High Side Pressure

Scan Tool Displays 0.00 to 5.00 volts. This represents the A/C refrigerant pressure sensor signal. The amount of pressure indicates the amount of load that the A/C compressor is placing on the engine. The PCM uses this information in order to adjust the idle and to control the cooling fans.
