Cm2250 nox sensor power wire failing load test

[Gcc]

The only way i can get codes to become active is with egt 550 plus. Below that for a few minutes or even running empty code goes inactive over 550 it come on almost like clock work only thing i can find correlating with it I’m watching everything on insite. I’m going to try another ohm meter tomorrow see if its different but key on i get 60 and when i turn key off u can watch it drop to 0.00 an the meter scans all the ohm settings automatically and shows 0.00 turn key back on bam 60 again
