alright first off, got full exhaust on my truck and 2 of the sensors broke off and my machanic said he can just plug them and it should be fine
ive got the spartan tuner, so will that allow me to not run the senors?
and also, he said he cant get the truck started and that the starter sounded like it blew a fuse and that the starter isnt getting any power.
any ideas on this and what happened?
hes got the 250 tune loaded.

You have to have the sensors in with the spartan, and that's why its not starting more than likely.

You'll need to buy new sensors from ford and put them on.

Why does everyone say you need the sensors in? Is it just strongly recommended or what? I dont have any sensors in my exhaust, theyre tied up to the frame rail...didnt have any bungs to put in the exhaust when we did it, and I havent had any problems.

whoever broke them, tell them to buy new sensors and install them in the bungs.



then reload a lower tune like 210...... and re upload the 250. Should be good to go.

are you running H&S? That's the only tuner that you can leave the sensors unplugged.

Are you running a tuner and if so, which one?

Did you make your own straight pipe or just remove the sensors and plug the bungs?

How long have you been running the straight exhaust system and/or tuner?

Your truck will run for awhile without the sensors, then when it goes into a timed/mileage regeneration, your truck will go into "limp mode" and you'll only be able to go around 20 mph.

Do a search here on the forum for more information, get yourself a proper DPF delete pipe and install the sensors, before you run into trouble.

I've installed DPF delete exhaust on 4 of my trucks and have never broken a sensor. Hard to believe your mechanic broke several. Is this guy a mechanic or just a buddy with a set of wrenches? The sensors aren't cheap and I'd have him foot the bill!

He said there plugged in just zip tied to the frame, witch would work. Its just easier to get the right exsuast with the bungs and there safe there. zip tied to the frame they will be screwed and need new once if you go back to stock.

Which tuner are you running on your truck?

It's hard to help when we don't have your equipment info.

I'm looking to see if I have pricing info on sensors.

I copied and pasted this information from another Forum concerning the (1) pressure sensor located in the DPF and the other(3) temperature probes. I believe that the threaded fittings are the "bungs" welded onto the exhaust. These are Ford part numbers.


Pressure Sensor 8C3Z-9J460-B

EGT Probe 8C3Z-12B591-D

Threaded Fitting 7C3Z-9J454-A

The same thread said the fittings were $57.00 each, Dealer cost.

The dealer needed to replace my dpf because the mechanic could not remove one of the sensors. Never stripped a thread? Needed any liquid wrench?

So all the exhaust sensors are $57 a piece?
and the only place to get them is the dealership?

I must be getting old! I asked this question two times without an answer, then realized that my answer was in the original post by xnissanxminisx.:damnit:damnit:damnit

The pressure sensor on two of my truck's DPFs were tightened so much at the factory that they bottomed out on the inside of the DPF. Removing them damaged both the sensor threads and DPF bungs, but the damage was minimal and I was able to use a tap & die to repair them. I did use WD-40 to help lubricate the threads on the sensor as I was removing it.

Never had a problem removing any of the other sensors.

I've made it a habit of re-installing the sensors (whether they are going into a delete pipe or back in the DPF for warranty work) with a nice coat of anti-seize compound on the threads.
