I am trying to monitor the DPF on my Toyota.
There is a default called “DPF pressure” this gives me a crazy reading but I do not know how to edit or check the equation or even which pid it uses.
Also WIKI shows DPF pids of mode 01 pids 7A 7B and 7C.
7C is shown as DPF temperature which I am fairly sure is EGT B01S02 so does anyone know what the other two are? 017a and 017b or could point me in the right direction to find out please.

It is a Toyota Prado with the 2.8 litre diesel. Somebody has worked out how to monitor the soot % by sniffing the output from a scan tool.
Torque pro shows % soot or clogging, exhaust temperature of three sensors, including the dpf but I would like to be able to monitor more such as pressure differential across the filter, (there is a sensor) and possibly when a regeneration or burn is happening. Although of course I can see this now with raised temperatures and % soot falling.
I have read that some vehicles will give such information as how many burns, distance and time between them etc.

Forgot to say 2015 year of manufacture, it is the 1GD engine as fitted in the Prado, Hilux and Fortuner vehicles from that year onwards.

Thank you I am scanning now with header 7E0 as requested, this seems to take a very long time at present reached 224xxx
Any idea how long a scan takes and does the email function work as I have read that it doesn’t? hopefully the issue has been fixed?

just scan the address 2100 – 21FF
if you specify your mail, I’ll write to you at my mail address of my mail, to which you can send scan results
or you can put the data on any file hosting and give a link

I copied to myself the data you gave
I’ll write when I check it out.

Thanks to both of you for helping me. I have also heard from Ian saying the email bug was fixed a long time ago.
I am using a Chinese head unit with 10 inch screen in the car and will check that the version of torque pro is 1.8.199 Although I have paid for the app I fear that my version came with the unit and could be anything put on in China.

I have been monitoring the raw data (with someone else driving) but as yet have not been able to make any sense of it. I have also tried pids and equations published for other vehicle manufacturers but as expected these don’t make sense either.

I will update this thread with my progress.

I have installed your pid scanner on a galaxy s6.
It connects to the BT OBD adapter and shows under the red and green scan and stop buttons:
7E0 7E8 2100 21FF

Unfortunately when I press the green scan button absolutely nothing happens.

Have I understood the basics of this? there is no need for torque pro to be running? it isn’t a plugin for torque pro but a separate scanner?

I also checked that the version of torque pro was the latest and changed the obd settings to speed up the scan. this did make a torque scan faster but the email function still reports “cannot attach an empty file”

Edit I have checked to see if anything is logged and there is:
“PIDscan log:Device: “CAR-KITo” 17:D1:5E:18:0D:00Android 7.0 Close.”

I would try creating a custom pid to look
at bytes B and C as …

Int(B:C)

Int(B:C)/10

Int(B:C)/100

Do any of these results match
atmospheric conditions with
KOEO? (101 kPaA where I live)

For temperatures you might want to
fully read the following thread for the
Ford 6.7’s where “22F4xx” was equivalent
to “01xx”.

Since your posted result is so close to x8000
I would also test…

Int(B:C)-32768

(Int(B:C)*(1/10))-3276.8

(Int(B:C)*(1/100))-327.68

((Signed(B)*256)+C)

((Signed(B)*256)+C)*(1/10)

((Signed(B)*256)+C)*(1/100)

Edited.

Thank you, I will try what you suggest as soon as I get time, in fact I am happy to try any suggestion to try to get to the bottom of this.

As I am such a novice please would you answer this basic question which is still bugging me.
Is it possible to edit a default or built in pid in torque pro?
for instance I would like to know what the default sensor in torque pro is monitoring for “dpf pressure”. How do I find the details (pid and equation) for this?
