Compressor Protection Control at Pressure Malfunction
WARNING: This page is about a different car, the 2011 Nissan Murano. However, it is still accessible from the selected car via links, so may be relevant.
When the high-pressure side value that is detected by refrigerant pressure sensor is as per the following state, ECM requests IPDM E/R to turn A/C relay OFF and stops the compressor.
- 3.12 MPa (31.8 kg/cm2 , 452 psi) or more (When the engine speed is less than 1,500 RPM)
- 0.12 MPa (1.2 kg/cm2 , 17 psi) or less
