Post DPF active regeneration
on: August 12, 2019 (GMT)

The DPF temperature sensor is not available to my ELM327 (Jaguar 2014 facelift version, 2.2 Sportbrake),but an earlier post mentioned that the MAP sensor could provide an indication of when an active regen was taking place – the air pressure would drop. Mine shows a fairly constant 98-100kPa – will this drop when a regen is occurring? I’d like to alarm it – would a low alarm setting of say 90kPa work for me?.

Thanks cintak, I’m new here and finding my way around. When I open the OBD2 PID Editor, I am unsure of how to fill in the blanks – Long name, Short name, min and Max values, scale factor, unit type, Equation, etc.
I’d appreciate some guidance thanks.

it doesn’t matter, for example, and make the PID Test

PID: 220417
Long name: Value
Short name: value
min: 0
Max: 100
scale: x1
unit: –
Equation: A
Header: 7e0

Hi cintakc, I got 0.0 results for 220417 and 220434, but for 22042c I got “result for equation 60.0 response 7E80562042C3CE6”
But then when I selected Test Results on the main menu, I got message “ECU does not appear to support mode ”
Not sure if this is a dead end for me now, but thanks for your input.

Many thanks cintakc, I’ve now got a “Soot DPF” reading. It is 23.8. I presume I can take this as a % full, so will keep an eye on it and perhaps set an alarm level at 40 so I can give things a blast.
You’ve been a great help even although I can’t quite follow where the figures come from!!

it is necessary to control the readings for several days, whether they will change
maybe this is not suitable for your car

if I had more data about your car, I could more accurately see the parameters for DPF
