Urea Temperature Sensor Inspection: Notes

NOTE:

If measurements are taken with the vehicle on an uneven surface, a correct urea level cannot be detected because the urea tank could be tilted. When inspecting, take measurements with the vehicle on level ground.
If the ambient temperature is low, the DEF may have frozen and the DEF level may not have been detected correctly. If the ambient temperature level is below freezing, take the measurement after the DEF has defrosted.
