A/C system operating pressures

[psbnsx]

Hi, Everyone

Is anyone knowledgeable about the correct A/C system operating pressures for a 2001 NSX? By that I mean what are the correct high side and low side pressure ranges for the a/c system. I can't find those values here in "prime", nor in any of my a/c books.

Thanks in advance!

I'll check in my service manual when I get home and see if it says anything.
Since my car is a 3.0L I don't know if the 3.2L is the same. That is assuming your car is a manual and not an auto which would have an auto.

The manual gives a multi-axis chart, so there's no simple answer. Depends on ambient and evap temperatures. From one of my generic AC shop manuals, a R-134a system should have a low side pressure of 16-29psi for an evap temp of 33-50*F, and a high side presure of 115-200 psi for ambient temp of 70-80*F. Ballpark figures of course.

I believe the '92 still used R-12.
