Problem is once u delete and get rid off all the emissions.... there’s problems if you decide to trade the truck in..... dealers can’t take that truck on trade unless the emission system is fully intact and operational. If you are like me and keep trucks forever then it may not be such an issue. Most states now are cracking down on rolling coal, deleting, ect.....so if it would be me.. just replace the sensor and keep the system cleaned. I personally don’t worry about that crud anymore cause I run gas engines now. But for those who need or want diesels, requires a little more work now then “back in the day” required... Good luck
