After installing a new compressor, dryer and expansion valve in my '95 S320, I am getting the EO 45 and EO 47 errors for the refrigerant pressure sensor, open or short circuit. (thanks to K6JRF's great page!) The compressor runs for a few seconds and turns off for a few minutes and starts the cycle over again, all pressures are correct. Do I need to replace the refrigerant pressure sensor or could something else be creating the open circuit?
Thanks!
