Fault code: EMS 41089 SCANIA

Finding the fault code

Enter the fault code System

Fault code:

Exhaust gas temperature sensor upstream of SCR catalytic converter T113

The voltage in the circuit has been outside the permitted range.

Short circuit in the temperature sensor circuit before the catalytic converter.

If the voltage is outside the permitted range, the control unit uses a pre-programmed value of 0°C.

Check the circuit components, harness-to-harness connectors and electrical cables.

Measure the resistance of the sensor. If the temperature is between 10 - 30°C, the resistance should be approximately 207 - 222 ohms.
