International DEF Sensor

I found a supplier at Mexico, they recon all kind of QLS sensor, I mean damaged by leaks or lack of singnals, we have sent more than 30 sensors all of them were repaired,

 

Any one know how to change out a def fluid sensor on a 2015 international prostar ???

 

I can find videos on how to do this on about every semi except an international its frustrating

 

Where are they made, you ask ? China . .. . Mexico . .. . Vietnam. .... Who knows . . . .. .

 

Already change the qls sensor and heater coolant valve and the low deer sensor check engine light with the triangle and warm engine comes out you know what it is

 

Change the two sensor qls and the heater coolant valve then drew one day the next day the low deef sensor comes out then goes away then comes again anyone knows what it is

 

Only way to find out is by pulling the codes with a reader. Also, check your fuses for the def header. If it's a freightliner, they are usually on the firewall by the driver side. I've seen the fuse for the def header heater go out quite a few times.
