Mad Ram Trucking Posted July 26, 2023 Share Posted July 26, 2023 I just read about taking out the outlet nox sensor to keep the truck from going into derate but how do I get the derate to stop to begin with?

Mackpro Posted July 26, 2023 Share Posted July 26, 2023 Use good DEF fluid ( not out a jug ), keep valves , and injectiors and engine brake plungers adjusted, get DPF filter and cat cleaned every 2 years. Keep EGR differential sensor ports clean. Have dealership check truck for software updates in the engine and after treatment ECM,s. Make sure both nox sensors and the newest part numbers and not counterfeit if they have been replaced. No boost pressure leaks anywhere at all . Newest EGR differential pressure sensor and venture pipe installed . Boost /temp sensor clean and not soot caked. I could keep going for ever but in reality, everything has to be perfectly maintained and operating for the system to be trouble free.
