A011 - High Side Temp Sensor Circuit

S073 - Right Rear Accelerometer Fault

My 2 current codes.

Can anyone elaborate as to what they mean? I get a message about my AC refrigerant being low & service ride control.

A011 is an A/C code. The sensor is the one on the A/C line along the firewall closer to the drivers side. Have the system charged and see if that fixes it since you have the low refrigerant message.

S073 is the reason for the other message, but I don't know much about that one.

System was charged about 6 weeks ago. No leaks at the time. The AC worked for 2 days then the message came up about the refrigerant. Could the sensor be bad & my ac system not be leaking?

In that case I would replace the high side AC switch. Your GM dealer should have it. And I'm sure others on here will post a picture to help you identify the sensor....

Well, if the system is still charged then it might be a bad sensor, but the system will have to be evacuated and recharged to change it.
