Scania fault code 4174

EMS Engine Management System Exhaust gas temperature sensor upstream of SCR catalytic converter T113 Implausible signal in T158 1, Temperature sensor at silencer intake. The value is lower than the calculated temperature. Read explanation → EMU Heater H39, internal fault Heater H39 has detected an internal fault. Read explanation → EMD Exhaust gas temperature sensor upstream of SCR catalytic converter T113 Implausible signal from exhaust gas temperature sensor upstream of SCR catalytic converter T113. The value is lower than the calculated temperature. Read explanation → EME Exhaust temperature sensor, temperature too low Implausible signal from exhaust gas temperature sensor T158 upstream of SCR catalytic converter. The value is lower than the calculated temperature. Implausible signal from exhaust… Read explanation → EMO Exhaust gas temperature sensor upstream of SCR catalytic converter T113 Exhaust gas temperature sensors before the SCR catalyst (T158) signal is not plausible. The value is lower than the calculated temperatureExhaust gas temperature sensors before the… Read explanation →
