I get the same approx results for all the EGT readings. EGT14 tends to peg sometimes and all the others seems to get no data briefly. But they all give good results commensurate with what I would expect based on the senors location.

Distance Since Last Completed Regen behaves as previously mentioned. It only updates after the key is cycled. It seems I haven’t had a completed regen in over 400 miles.

I tried 042C for DPF Percentage Load and DPF Soot Concentration with no luck (I didn’t expect any). Returns an unchanging value of 120.

MPD56, the DPF equations above are for the DPF sensor, correct? If yes the range of the sensor is 0-80 kPa (0-11.6 psi). The PCM calculates soot load based on the diesel particulate filter pressure. Not sure if this helps with your calculations. I too would be interested in a calc tutorial. I do some programming…mostly in Excel as it relates to metrics/stats in Clinical Research. I can’t imagine there’s much of a parallel here tho…

I’ve been hunting the soot levels and came across some XML referencing the DPF and soot PIDs.

PID id=”DPF_SOOT_INF” read=”yes” write=”no”
acronym=DPF_SOOT_INF
description=Hot$DPF_SOOT_INF
Description=DPF Soot Concentration – Inferred (grams/liter)
module=PCM

Typing reply while you edited your post.
I believe that DPF_SOOT_INF is the PID to find?

Still testing the DPF. I believe that the PID for the pressure sensor alone won’t give the soot load. I’m thinking the DPF pressure constantly changes with exhaust flow rate. I’m not sure if 2013 6.7L has a PCM internal calculated output for soot load, but I’m thinking that’s the PID I have to find.

MPD56:

Are you saying variable E increases
with throttle?

So do you think C&D could be your
dpf psi? or E&F?

Maybe the first bytes are the pid Bridge
mentioned… seems too low for psi.

((A < 16)+(B < 8)+C)*(1/100000) Edit: http://torque-bhp.com/forums/?wpforumaction=viewtopic&t=2807.0

The DPF 2, C&D showed 2.7 to 3.0 on gauge valve. Increasing throttle while testing increased the Equation number. Also increased the numbers after 7E81009417A and 7E82

I think the Soot Level shouldn’t change up and down with throttle, wouldn’t it be an accusative valve.

How would I make an active PID out of 0x42c

Thanks for the Link

That looks like some kind of
can address not obd. Really
dont know what to do with it.

I would watch these over time
to see what happens when you
are near regen.

Maybe one of the bytes will
increment over time.

Edit:

Some other pids to try when you
get a chance…

EGR 016B
CACT 0177
MAP 0187

PM 0186

Yes, the soot level should climb and not waiver up/down per the values I’ve seen on the commercial readers. Generally around 2.66 is when a regen is initiated. The regen is complete when the level gets back to ~1.15.

Re: Ford 6.7 Diesel PIDs

Hey Folks: update.
Had a chance to compare with a commercial monitor for the EGT sensors. Although I couldn’t have both connected at the same time I assume that they are close enough for me to grasp what’s going on.

FYI:
I monitor #2 and set an high alarm (1150) to tell me when I’m in Regen (Till I can find the right PID), I monitor EGT1 to let me know when the turbo is cooled down after a long trip and #4 because it is the easiest to compare with a IR thermometer.
Also It seems that Distance Since Last Complete Regeneration (DIA – PID 220434) has kept up with the same readings as the odometer, will have to see if it reset on the next completed Regen. It still only adds the mileage when you restart the engine at the start of a trip.

Hey Capp777: (Was just writing a reply)
Have been around just went back to learn some of the basics so I would get more confused. Going to test some today. Thought I give you a rest.
Says Equation for 017A (Soot Level) is invalid.
Seen other monitors coming out reading DPF PIDs so I’m assuming that Torque Pro can do the same, Right?

Thanks for the check-up.

Re: Ford 6.7 Diesel PIDs

Maybe changing (1/100000) to 0.00001
will work? The math from your earlier
posting of the test response (02 00 32)
yielded 1.31122 which would be in the
ball park after the active regen you had
just went through.

Its there somewhere we just have to find
it. The mode 1 pids may hold the key to
others if they respond. PM (particulate
matter sensor address has also got me
curious.

I didnt know if the manual regen link
would help you guys… but I posted it
just in case.

The EGR Temp pid which Bronco posted
accidently for EGT was showing data that
was changing from shot to shot which
looked like it could be the EGR Temp.

His screen shot for fuel level was yielding
~61 % which seemed reasonable but only
you guys can answer that.

Fuel Level %? (Seems to work on my 6.7, thank you)
Header: 7E0
Mode/Pid: 22F42F
Unit: %
Equation: A*0.39216

Also the Fuel Level (From Engine ECU) from the standard list in Scan Tool seems to work. Is there a way to look at the equation, etc of the PIDs on the torque list or are they top secret?

Also I have never been able to complete a scan with Scan Tool; it always ends up with a scan failed?

I believe that there are at least 37 PIDs that Torque Pro should be able to monitor for the 6.7L. From what I’ve been reading, only 23 to go.

Some of the equations for generic
mode 1 pids can be found on this
link…

http://en.wikipedia.org/wiki/OBD-II_PIDs

For the newer pids I suggested you try I
would start with the known equations
i.e., MAP, Baro and ECTs.

You didnt mention the 0.00001 fix to the
soot gpl? equation nor the EGR Temp pid.

Does this mean they didnt work?

Capp777:

I couldn’t get to the equation with Soot to be valid and save a Custom PID, yesterday. I had luck today, an added Custom PIDs 017A, 017B and 017C and will try later to today.

The Standard Bar PID is showing 14.4 on the dial and not changing value.

I believe that one of the ECT PID, I posted is reading correct. The 6.7L has two coolant circuits and I believe that the one I am monitoring is for the Primary Coolant System by the reading.

As you suggested, I’ll work on the generic (Standard) PIDs, in my mind I was thinking that they would be too easy to figure out, I did try a few and didn’t add them to my list. It just wasn’t fun with getting the easy ones LOL. I did step back to the basics to organize my confusion

Thank Again!!

Re: Ford 6.7 Diesel PIDs

If you get a response for 0167 it
may have both ECTs in its response.

If standard baro is not working you
can hardcode the MAP value at KOEO
or use the baro from your phone until
Ian provides the Baro() function.

Edit:

Unless you are changing elevation
I wouldnt expect the baro (0133) to
change much short of weather changes.

This worked for me too but I didn’t get a screenshot.

My soot level equation came out to this, and I drove around for a few miles and it didn’t really change. Its VERY VERY cold here though and I hear that sometimes doesn’t cause it to go up as fast.

The distance since regen (220434) comes up but I will have to watch to see if it changes for a few days.

Thank you all again for all of this information! We have made so much progress!!!

Some more to try…

EGR Temp (EGR_COT?)
Header: 7E0
Mode/Pid: 016B
(((B*256)+C)*0.0064)-4.0 or standard
(((B*256)+C)*0.007)-40.0
(B*1.8)-40
(C*1.8)-40
B*0.39216 (% for EGR Valve Position?)
C*0.39216 (% for EGR Valve Position?)

CACT1
Header: 7E0
Mode/Pid: 0177
(B*1.8)-40
(C*1.8)-40
(((B*256)+C)*0.007)-40.0
B*0.39216 (% for ?)
C*0.39216 (% for ?)

MAP?
Header: 7E0

Boost?
Header: 7E0

(((B*256)+C)*0.03625)-[33]

ECTs?
Header: 7E0
Mode/Pid: 0167
(B*1.8)-40 (ECT?)

(((B*256)+C)*0.007)-40.0

EBP?
Header: 7E0
Mode/Pid: 0173
((B*256)+C)*0.03625

Need more info for NOx maybe at
or during regen?

If Soot gpl works it should read around
~2.66 gpl at regen. This is a longshot guess
based upon the data. Maybe we will get
lucky. If you can post a test response for
017A at start of regen maybe we will see
the other bytes as well just in case.

Bronco… Thank You for your posting of
the test responses! Without them I am
blind.

All of these will need to be verified against
a calibrated source. The equations given
are based upon similiar formulas that
were used in the past. The formulas may
be different for your 6.7’s.

Hope these work for you.
