P0533 A/C Pressure Sensor High.

It could be low on refrigerant, or it could be a bad sensor. Back-probe the pressure sensor connector (on the discharge line, near the compressor - it's a 4-way connector) on the dark blue wire with the engine running and the A/C turned to max. If you get no volts, or 5 volts, the sensor is bad. 4.5 volts indicates a properly-operating system, while less than 4.5 indicates low pressure, and anything above indicates high pressure. If low or high pressure is suspected, verify with a set of refrigerant gauges.

If warranted, the sensor can just unscrew. You won't lose refrigerant - there's a valve built in to the line to prevent that. Make sure to use a new O-ring and lube it with the proper oil if you do change the sensor.

DTC P0645: A/C Clutch Relay Control Circuit
Circuit System Description
When the A/C switch is pressed, the HVAC control module sends a serial data message to the ECM. This input will request the engine control module (ECM) to ground the A/C compressor clutch relay control circuit, which will switch the A/C CMPRSR CLUTCH relay on. With the relay contacts closed, battery voltage is supplied to the A/C compressor clutch assembly.

What is a po532 code on a 2008 hhr ss


DTC P0532: Air Conditioning A/C Refrigerant Pressure Sensor Circuit Low Voltage.
The engine control module (ECM) monitors the high side refrigerant pressure through the A/C refrigerant pressure sensor. The ECM supplies a 5-volt reference and a low reference to the sensor. Changes in the A/C refrigerant pressure cause the sensor signal to the ECM to vary. When the pressure is high, the signal voltage is high. When the pressure is low, the signal voltage is low. When pressure is high, the ECM commands the cooling fans on. When pressure is too high or too low, the ECM will not allow the A/C compressor clutch to engage.

Switch number 1 on the cruise brakes has low voltage on the circuit. Or how about low voltage on your brake line switches or something? Check to see if inadvertantly the connection to the actual pressure switch (one for front & the one for the rear) may have pulled loose at the switch. These are located in the Hydrolic fluid line...
