Device mac=00:00:00:33:33:33
Device Version (Declared)=ELM327 v2.1

most likely this speaks of a fake adapter

Yes, most lickely it is fake.
But it can make some commands.
What PID should I use in my car for % DPF Shoot?

Hi everybody. My name is Juan, from Spain, so sorry for my level of english.

I have read all the topic and have not found any information about DPF pids for GM A20DTH engine. I’m trying to check parameters as distance from last regeneration, percentage of saturation, and current status of regeneration, and have no idea how to get it.
My car is an Opel insignia 2.0 diesel from 2011, i’ve tried the pids posted here used for an 1.3 Astra J diesel, but it doesn’t work on my car.

Does anybody know the parameters I have to use for this engine, or either the commands to get an answer to calculate it?
My Torque app have pre-installed two PIDs, just for you know: DPF pressure, and DPF temperature, and they do work.

Thanks so much for your support.

You say 017A and 017C (DPF Pressure
and DPF Temperature) work for you?

You might want to test the hex responses
to see if other sensors are included.

Hi again, and happy New Year to all.

These are the answers I got by testing the commands you said:

Responses for commands 017A:
009
0:417A01001400
1:000000

Responses for commands 017C:
00B
0:417C01047100
1:0000000000

End Quote.

Both of those responses are showing sensor
data on bytes B and C only.

Does your vehicle support?

0180 – (PIDs supported)

0185 – NOx/Reagent related. See page [9] of this thread.

0186 – PM related.

018B – (Used in Ford 6.7 threads for more DPF stuff)

Does 73.7°C (164.7°F) seem reasonable?

0.029 Psia? 0.200 kPa? 2.0 mbar? 0.002 bar?

Since these pressures are below atmospheric
it is likely a delta p. assuming readings are
also reasonable. If so, its readings may be +/-
requiring either a signed() or -327.68 form of
equation. (Though in this case the latter
wouldn’t make sense with readings below
0x8000).

Edited.

\\I don’t understand what this implies.

\\Do you mean I must check responses for 0180 and 018B or what? Sorry for my misunderstanding.

\\I don’t know much about DPF normal temperature, I guess it’s not reasonable.

Your posted hex responses indicate only
one sensor is supported for both 017A and
017C.

My understanding about DPF temperature is
that during regen temperatures can reach very
high temps (above 1000 °F). Your posted data of
0x0471 seems to match typical transmission
temps. I assume your vehicle wasn’t in a state
of regen when you recorded the data. It seems
reasonable if your vehicle hadn’t been running
long. Definitely worth watching before, during
and after regen.

If your vehicle supports 018B, there may be
additional useful info. Testing its hex response
will show if it is supported.

When you said that 017A and 017C worked,
what values were the built-in pids showing?

I was under the impression that these pids were
“place holders” only because the other sensor
data has not yet been defined in Torque.

Hi,
I wonder if anyone can help, I’m struggling to get any PIDs to work for DPF.
Mine is a 2011 Vauxhall Zafira B with A17DTJ (diesel, 1.7 CDTI, 110 HP, DPF installed).

I added a push button to send OBD commands, and tested:
2CFE002C = NO DATA
AA04FE = NODATA
AA0118 = NO DATA
AA0329 = NO DATA
2220F2 = 7F2231
2220F4 = 7F2231
2220F5 = 7F2231
2220F6 = 7F2231
22131F = 7F2231

Also changed init string to:
atsp6\nath1\natsh7e0\natcra5e8
Tried again, all above values the same.

With both init strings I still got other data, engine coolant temperature, RPM, throttle position, etc, so ECU communication is working.

Can anyone advise on correct DPF for the A17DTJ engine please?
Thanks.

Don’t forget to test the mode 01xx pids
discussed above.
