Question for my VNL fam !
Got the ol’ P2453: Diesel Particulate Filter Pressure Sensor "A" Circuit Range/Performance.
Apparently this has been on a while without the check engine light and has now stamped as permanent code !
Of course I operate in California and have to deal with CARB . Also … I found out during my smog lol ! So I replaced the sensor, those 2 little silicone hose were trash so I replaced them with just regular fuel line ( I KNOW, the dealer was closed at the time ) i ran a forced regen , I Did NOT reset aftertreatment system/sensors (I know , mechanic said it would reset data needed for smog test) …
Questions is , what is the drive cycle for the code to clear and monitors to set !? I’ve put 288 miles on the truck and only 3 monitors are in ready status .
I do not want to clear anything because they are continent to pass the test !
I’m allowed 1 permanent DCT with no more than 1 active code, no more than 1 incomplete monitor , 15 warm up cycles , 800 minutes of run/idle time .
I don’t know what to do ….
