Forscan lets you see ac data like compressor pressures and commands

 

I changed the high pressure sensor, tought it was fixed and then on my way home from work today it started acting up again. I have looked around and am unable to find the low pressure sensor. Can anyone please point me to the location of the low side sensor? As always any and all help is greatly appreciated. Thank you.

 

I hooked my gauges to the truck just put of curiosity. I could get about 125/25 . After running for about 15 minutes it did start to build pressure up to about 160/30.

Thursday after I swapped the sensor I was able to get about 185 on the high side. And about 35 on the low.

Is this information useful to diagnose my problem?
