Cummins x15 scr intake sensor

It’s early and I’m lazy

 

ESN or Model year?

The SCR intake temp is after the DPF and at the inlet of the SCR. Depending on the year it could be a stand alone sensor or if its newer it will have a sensor module with both SCR temps combined in a module. Da, you said X15. Its a EPA 17 and a combined module if so. All DPF and SCR temps are in one module. Its the spider looking one with 5 cables. Might have to roll the sytstem to get the probes out. As the sensor are long and sometimes they hit the brackets before they come all the way out.

Do you have any voltage faults logged or data erratic for that sensor?

 

He knew it was my birthday and didn't wish to bother me.

 

Happy birthday

 

This is a datalinked sensor. If faults are all logged and Inactive and recent, good chance you in fact have a bum sensor module.

Wiring checks are easy. Check for battery voltage and ground to the sensor. I ussualy load test with a healight just to make sure its nice and bright, not a green wire. Other 2 wires are datalink(green/yellow twisted). Should measure 60 ohms plus or minus 5, key off and powered down.
