What are the sensors in the DPF for???

[Stroken49s]

When putting a DPF delete pipe on, one of my sensors would not come out.. I am ordering one from ford, but was wondering what would it do to the truck riding without it for some time.. No CEL is on

With the latest update to your Spartan tuner, you won't need them in the exhaust anymore. Without them in the pipe with the earlier software, your truck would not crank. You would need to clear codes and jump stat the truck.....or clear codes and let it sit for 60 minutes without cranking it.
