Yeah ordered from rockauto just wondering if there is a part # with an actual schrader valve for the high pressure port that swaps in.Amazon isn't the way to go.
Rockauto.com or autozone.
Looking at the diagram and see how it reacts. I think you answered your own question in this paragraph.The AC High pressure sensor is changing while the car is off, power on. I did all the diagnostics and everything passed up until the "Diagnose/Replace B1 AC High Pres Sensor" So the circuit is good, it's either the sensor or the actual PSI on the system is wrong. Don't get why the pressure would be jumping around while the car is off though.
The P0533 S0 is Sensor Circuit High; yet the sensor is reading low and jumping
