Proper Referigerant Pressures

My 07 Yaris Sedan is blowing warm air when I turn on the A/C. Before I bring it to the shop, I want to check the pressures and see if a recharge might fix the issue, but I can't seem to find proper refrigeration pressure anywhere. Does anyone have the spec for low side pressure?

Is it not under the hood on the sticker?

There's not really a concrete right answer to your question, as the pressure reading on you gauges will fluctuate depending on temperature, elevation, and other atmospheric variables where you are. Your gauges will read different when it's 70 degrees outside than when it's 100 degrees outside. Generally though, your low side readings will correspond with the temp coming out of your vents, roughly. If your high and low are equalized(reading the same), then something is wrong.
