Fault code: 5168 SCANIA

Error identification:

The signal from exhaust gas temperature sensor T113 is not plausible. The temperature is lower than the control unit expects.

Cause:

The exhaust gas temperature sensor upstream of SCR catalytic converter T113 is faulty.

The fault may also arise if the exhaust system is converted.

Notes:

The fault results in no reductant or very little reductant being added.

Action:

Check the exhaust gas temperature sensor and electrical cables.

Check the exhaust system.

To verify that the fault has been rectified and that the fault code does not recur, you can click on fault code monitoring and look at the fault code. This fault code is not activated immediately. In order for the control unit to set an active fault code, the fault must occur in four consecutive cycles, i.e. the power must be turned off and on four times with the starter key. You can use fault code monitoring to see whether the fault code is pending, i.e. the fault code is about to be generated.
