cad93 Posted July 19, 2005 Report Share Posted July 19, 2005 Newbie to this forum. I'm having a low refrigerent error on my 93 Seville with code A048. My low and high side pressures are ok and if I turn on the compressor by jumping the relay I do get cold air. When I clear the code it comes back within 30sec. When I check the ACP data I noticed AD33 is at -39 and doesn't change. I'm wondering which sensor is AD33?? When I disconnect the low side temperature sensor AD28 reads -39 When I disconnect the high side temperature sensor AD27 reads -39 When they are connected they read positive numbers and seem to work properly. Can someone help me with this AD33? I think this is why my compressor relay doesn't activate. BTW great forum and thanks for the help . Link to comment Share on other sites More sharing options...
