It looks like the p0533 and b1324 are the ones to be concerned with. They both mean the same thing. You have a pressure switch fault indicating high pressure(in excess of 430 psi). I believe the sensor is in the smaller line down near the compressor. Check and see if it is plugged in. The DIM is seeing 5.00 volts on this sensor, which indicates high pressure. You could have a sensor fault, disconnected or poor connection, open wire, or faulty DIM. The pressure ports are at the rh end before and after the variable orifice, by the underhood fuse block. The three wires at the sensor are: Pin A(black) to pin 50 at pcm, Pin B(gray) to pin 67 at pcm, and Pin C(red/black) to pin 56 at pcm. Pin b is the 5-volt line, pin a should have continuity to ground. If all else fails. Check wire continuity of each wire from the sensor to the pcm. All the wires are in the blue pcm connector.
