Well, the Home Depot across the street doesn't sell M20 bolts, so I guess I'm just going to run it with the hole open. Should have kept my old bad sensor from a year ago, could have used it as a plug...
-
leave the hole open. no problem.PermanentTourist Thanks this.
-
So did that work? Code cleared? Truck will run?
-
Diesel additive, available at Walmart.PermanentTourist Thanks this.

Ok, the sensor is dangling freely in the air.
Now the next problem...
My DDDL is weird and obsolete, it won't let me do a force regen through the computer.
I guess all I can do is let it warm up and run a button regen and see what happens. Unless there is some sneaky way to force a regen with this old software. It's weird, it shows me all the data from the one box, but doesn't let me talk to it. -
Obviously written by a former divorce attorney.sealevel, Bumper, mhyn and 1 other person Thank this.

You don't suppose where it says the last update you did was 2017 days ago has anything to do with it do you?91B20H8, Sirscrapntruckalot, Bumper and 2 others Thank this.

The fact that I bought it on Amazon for 50 bucks from some weird Lithuanians might also be a contributing factor91B20H8, Bumper and Dave_in_AZ Thank this.

your software is very old and hacked... Will not work for sure if you are unable to start parked regen by using software..Bumper, PermanentTourist and Dave_in_AZ Thank this.
