Hi,

I believe there is only one pressure sensor on this system. It should be located on the liquid line.

If you look at pic 1 below, it shows the wiring schematic for the system. Pic 2 shows the pressure sensor location on the liquid line.

I'm not sure what is happening, but here is a link you may find helpful. Take a look through it and let me know if you have questions.

Take care,
