How many bytes were returned on 22017B?
It could be Ford is mimicing the mode 01 pids
using mode 22 pids.

If it is mimicing then maybe 22016B will yield
egr temp?

I’ll get back to you on that. The last post took alot of my time LOL.

I appreciate very much the
all the feedback you are giving.

The truly sad part is not only do
I not have a 6.7 but I drive an old
obdi jeep. The only time I get to use
the dashboard is on family and
friends vehicles.

Very grateful for your time and
your sharing. I have learned a lot
just by helping others like yourself.

I wasn’t too far off for the alarm
EGT12 > 600 lol.

Its interesting to note that EGT13
stayed around the ~1000 degrees
we read about. Just didnt realize
that EGT12 would be hotter.

Based upon your startup readings
from before and this data I am
thinking the order is correct. IMHO.

I also believe that the DIA dropped
when you interrupted a regen that
just started and didnt totally reset
until the full regen was completed.

Now if we only had positive and
negative direction edge triggers
we would be set. :-)

I think I got the DPF PID from TXD 07E00322116c. All the other TXD numbers have fewer digits (e.g. 07E0022XXXX).

I understand your concerns about the “b” in the PID for the EGR 07E022F46b; I’ll play around with that later today hopefully and try PID 22F46c.

I was thinking about that 22017B you
were using earlier might be Fords extended
pid equivalent to the mode 01 pid 7B listed in
wiki for DPF which supposedly returns 7 bytes.

If that is true then maybe your other sensors
can be found in the 220001-220200 pid range
by adding 22 to the mode 01 pids and looking
at the responses.

I listed the EGR Temp above as a trial case to
see if it would respond with meaningful data.
(22016B).

I hope I didnt confuse you and Bronco.

Update:

I’m thinking that this DIA PID is close. I made trips and when I start up the engine, the gauge updates that matches the odometer, accept the last trip it seem to update when I was backing into a parking spot. As usual I will continue to monitor.

PID – 220434
Long Name – Distance Since Last Complete DPF Regeneration
Short Name – DIS
Min Value – 0.0
Max Value – 700
Scale Factor – x1
Unit Type – Miles
Equation –
OBD Header – 7E0

Note: I did changed the Short Name on this post to match the reference material I started with (my previous posts I name it DIA). I thank Capp777 for the equation. I set the Max Value to 700 because I usually like the gauges to read at the top (Half Scale) of the gauge at normal readings, although this gauge readings depends on a lot of things.

Capp777:
You didn’t confuse me, that is my normal state. On to the next piece of the puzzle!

For some reason it wouldn’t let me post the equation for DIS above?

((A < 16)+(B < 8)+C)*0.24 This PID seems to be working. PID – 2216c1 Long Name – Fuel Level Short Name – Fuel Min Value – 0.0 Max Value – 100.0 Scale Factor – x1 Unit Type – % Equation – ((A*256)+B)*(1/38) OBD Header – 7E0

Interesting that 2216c1 matches pid that
was used in 2004 Fords for fuel level.

Thanks for pointing that out. That gives me another Idea; I’ve been trying to find just new PIDs for the 6.7L when I should test some old ones. Of course the ones I really want are the ones for the DPF and they seem to be new LOL.

Still strange that there are 1600 views of this thread and few responding? I’m glad for your help, without you, I’d be a one man band without an instrument.

Since 22116c didnt work I would look
hard at mode 1 pids: 017A and 017B responses
using the equation for dpf psi.

The mode 22 pids: 22017A and 22017B
as well.

I didn’t get a response for 017B, 22017A, 22017B

I did get a response to 017A
Response from Equation -0.73138

I didn’t write down the other command response because I thought it would stay on my phone when I disconnected, but it didn’t. I’ll write it down next time.

Based on wiki 017A should return
7 bytes of data. You might want to
create displays for the different
variable combinations and watch
to see which may work prior to
your regens.

I am guessing that as your DPF
becomes more obstructed with
soot that the psi will continue to
rise.

We’re all waiting patiently to see if you guys figure out the regen monitoring. I’d gladly help if I had any clue how to program. The most I can offer is information from the service manual (which I’m sure you already have) and information from my own Torque app for testing.

Also watching are the companies that currently offer products that monitor the regens and other DPF parameters through their products. I doubt they’ll chime in with any help.

Sorry guys, I haven’t been driving the truck much this past week. I will have some time tonight and able to go out there and do some testing. Anyone have some specifics that need to be confirmed?

Thanks Folks:

I too would like to know the Regen Information, I use my truck also as a daily driver and it would be nice to know when it is close to going into a Regen. I hate not completing a Regen and I don’t always see the message that is up for seconds. I also owned a 6.4L and believe that miss completing Regens is hard on the Engine, DPF and MPG.
I don’t have a Service Manual and Capp777 doesn’t own a 6.7, so we are guessing on a lot of things (well me more then him).

The other companies are going to find it hard to reduce its cost against a App. I believe that only one company has a monitor out for a 2013 6.7L and with the EPA rules on Tuners it only makes the information a bigger kept secret.

That said! So that leaves it to us. I’d appreciate you trying the PIDs and letting us know if you are getting the same results. Also if I have left a PID out from my list that you would like, I’ll post it if I believe it is working and worth it. DIS would be helpful info because I think it stops increasing when it starts a Regen and zeros when the Regen completes. EGT12 increases over 1000 degrees a few seconds after the message displays, once I confirm this, I’ll probably set a high limit alarm at 1100 degrees.

I think that the soot level is determined by a threshold of exhaust gas flow rate and the value of the DPF pressure sensor. This value is calculated by the PCM along with other permissive to start a Regen. So just knowing the DPF psi from the sensor isn’t going to really help because giving the engine more throttle is going to increase pressure. The big question to me is if the PCM has a PID that will give this PID out or is it kept internal. I believe that the Dealer can manually start a regen and would do so only if they knew that the DPF needed a good cleaning. I expect the PCM will send out a PID value so they can diagnose a DPF problem.

I am hoping soot level is included
in the 7 bytes of mystery data.

So don’t forget to try looking at the variables
as %.

I agree that air flow is a function of pressure, air
temp and density… flashbacks of square root
of delta p. plus the effect of soot obstruction.

Capp777:

Could you define variables and what I should try, also equations.
I did create some custom PIDs I’ll try tomorrow. Sample equation – ((A*256)+B)*(1/38)

I noticed that some Icons in the Manage Custom OBD2 PID page are “Current Data” and some are “ECM Custom PID”, do you know what this means?

I’ve loaded up what you have posted and will test over the next few days to confirm your DIS and EGT11-14 PIDs.

The Service Manual mentions two PIDs for Soot level (but doesn’t give the actual PIDs). One is a concentration and the other is a percentage. The concentration is “inferred” grams/liter. I’m experimenting with PID 042c to see what I get.

Would the current data be the mode 1 pid(s)
while the ecu custom pid be your mode 22
pids?

Can you post the test response so I can see
what raw data we are looking at?

A*0.39216 for % (variables A through G?)

((A*256)+B)*(1/13107) for volts

For the dpf psi equation and volts I would try
variables A&B, B&C, C&D… F&G.

Thanks again Capp777 for clarifying, I just wanted to make sure I was still on the right path. Since the only response I’m getting is from 017a, I’ll start with it.
The other problem I’m having is my wife is taking the Bluetooth Adapter away from me for a few hours a day, she thinks that I need to be weaned off it, (one reason I bought two adapters LOL).

Created 5 custom 017a PIDs
***************************************
PID – 017A
Long Name – Diesel Particulate Filter 2
Short Name – DPF 2
Min Value – 0.0
Max Value – 100
Scale Factor – x1
Unit Type – %
Equation – (((C*256)+D)*0.000135)0.8005
OBD Header – 7E0

Response:
Equation – 0.9275 (Gauge shows 3.0)
7E81009417A02003200
7E8213C00000000000
***********************************
DPF 3, 4, 5&6 Showed the same response for second number (7E82-13C000000000000) number after the “-” increased when increasing throttle. DPF 3 unit was psi, the rest %

DPF 3 – Equation (((A*256)+B)*0.000135)0.8005 (Showed -0.7 on gauge)
DPF 4 – Equation ((A*256)+B)*(1/38) (Showed 13.5 on gauge)
DPF 5 – Equation A*0.39216 (Showed 0.8 on gauge)
DPF 6 – Equation B*0.39216 (Showed 0.0 on gauge)

Hope this makes sense, starting to confuse me. Any one knows a Link to explain the basics for formulas. Hoping the developer will add to the Wiki, I’m scared of burning Capp777 out, he is doing all the work.
