Would like to know this too.

i believe its dependent on the ambient tempreture
I would think ambient temperature would not be relevant to the actual HI and LO cutoff sensors. Yes, relevant to charging the system. I'm just a A/C layman... :artist:

According to the FSM the values for the pressure switch located on the High Pressure Line of the HVAC system are as follows.
Abnormal refrigerant pressure:
Below 196 kPa (2.0 kgf/cm 2 , 28 psi)
Over 3,140 kPa (32.0 kgf/cm 2 , 455 psi)
If the pressure is over or under the listed values above, the HVAC system will set a DTC "23" and cause the A/C Amplifier to turn off the compressor.
"Standard" Operating range on the High Pressure Side is:
1.37 to 1.57 MPa (13.9 to 16.0 kgf/ cm 2 , 198 to 228 psi)
There is only one HVAC Pressure sensor located on the High Pressure Line on the passenger side of the A/C Condenser at the front of the vehicle.
