I have raw inlet sensor code the customer had it another shop they replace nox sensors urea pump and acm. Ddl8 is telling me the sensors are good with the nox sensor verification test

You could have a air leak on the cac system or just a internally new bad nox sensor like could happen, as long as you have 12v and 2.3 and 2.7 on your 4 cables. Sometimes software issues also affect this readings
