Scania fault code 8704

EMS Engine Management System Charge air pressure sensor The NOx sensor is not responding in time. Read explanation → EMU Water valve V243, feedback signal, short circuit to earth The control unit indicates low voltage on the water valve's feedback signal. Read explanation → COO Coordinator Oil pressure gauge The voltage in the oil pressure gauge circuit has been above the permitted level. The fault code is set if the voltage on coordinator pin 11 exceeds approx 18 V. Read explanation → MGU Sensor supply voltage, prohibited value The voltage supply to the sensor has an incorrect value. Read explanation → EEC Exhaust Emission Control NOx sensor downstream of the SCR catalytic converter NOx sensor T115 downstream of the SCR catalytic converter signals internal fault in the NOx sensor.
