2006 Prius A/C Temperature Stuck?

Conversion is pretty straight forward.

Low-pressure side: 0.15 to 0.25 MPa (22 to 36 PSI)
High-pressure side: 1.37 to 1.57 MPa (199 to 228 PSI)

 

You're looking 36 to 40 on the low side the blue the hi I rarely connect much anymore .

 

As you know, proper method is to evacuate and refill with proper weight.

Filling it by PSI is not accurate. R-134a chart can show approximate PSI values with humidity and temperature etc.

 

Seems to work ok for me; what happened for you?

 

Or ... chosen MegaPascals, not milliPascals.

 

Ah. So daveyedgar gave the prompt "mpa to psi converter", all in lower case, and Google honored the difference between m for milli and M for mega. As it should, I'd say.

But that means it is not ignoring case, so maybe it should kinda warn you about that somehow.

It would be easy in this example, given that the abbreviation for pascals is Pa, so it could say something like "I saw pa, did you mean Pa for pascals?".

 

If you don't understand that case is important. Having presented wth that question, you also might not pickup what the converter is subtly trying to tell you. Even then, you're focused on the question asked and will most probably not then apply that to evaluating whether you meant m or M.

 

I know by looking at needle on gauge. They'll be at certain clock positions. My eyes go across gauge set see the aporox clock Positions and move on to the rest of it. Gas do look differently on gauges according to outdoor temps and time running. It'll take about ten minutes to stabilize the cabin . That's wen you want to read gauges.
