Air conditioning (A/C) pressure (kPa)

Measurement range: -176 to +3277 kPa.

The engine control module (ECM) calculates the value from the signal from the air conditioning (A/C) pressure sensor.

The value indicates the pressure at the high-pressure side of the air conditioning (A/C) system.

The engine control module (ECM) calculates the pressure based on the signal from the air conditioning (A/C) pressure sensor. The pressure is given as a value relative to the atmospheric pressure.
