B27C8 Nissan Code - Compressor Suction Refrigerant Temperature Sensor Low
Quick Answer
The Diagnostic Trouble Code (DTC) sets when the compressor suction refrigerant temperature sensor recognition temperature is too low [less than - 66°C (- 86.8°F)]. Common causes include Faulty Compressor Suction Refrigerant Temperature Sensor, Compressor Suction Refrigerant Temperature Sensor harness is open or shorted, Compressor Suction Refrigerant Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
