Getting EGT readings with torque pro

[bilgeboy]

I got one of those cheap eBay odb2 dongles and downloaded torque pro. Has some good things, but I got it to see EGTs but it doesn't seem to work. Anyone done this before? I believe there is a few tricks to get some of the sensors to work, but haven't seen anything Pajero specific yet. There is a mits plugin but it was out of date for my android OS.

As I understand it, and could be wrong, the reported temperature is part of the DPF system, so I don't think it's called EGT as such. Have you tried looking for Cat Bank or DPF temperature signals?

Torque Pro can read Cat B1S1 temp.
Normal value is around 350 degC, during DPF cleaning the temp rise up to 750 degC.

I found the cat sensor so all good. I have the dpf delete but it still sees the sensors but not relevant obviously.
Interestingly, it threw a gearbox comms code, but it didn't do anything. I just cleared it.

Not a bad bit of kit, although the gearbox and engine temps are coming from the same sensor. I have a gearbox temp gauge already, so no big deal for me.

You need to create a custom PID in Torque Pro to read the transmission temperature. Try this:

This is for the Pajero with the Jatco box. Don't know if it works on the Challenger.

Go to Torque home screen and click on bottom Left Hand menu, then select settings, then, select Manage extra PIDs/Sensors. Now select menu in top right hand corner, then add predefined set, then Chrysler/Dodge, then Transmission Fluid Temp (GM Method 1). Now a screen will come up options for: Trans.FI.Tmp and select Edit, now edit it. Change the fields first line is the heading and under it is what to change it to
OBD2 mode and PID(in HEX..... to
2102

Short name (used in Display) to
Trans Temp

Minimum Value (typically 0) to
0.0
Maximum Value to
200.0

Scale Factor to
x1

Unit factor to
°C

Equation (eg A+B+20- or [0d]+10=A or even just [0d] to
f-50

OBD Header to use (leave blank, 'Auto' or HEX header) to
TCM


Then go back to Torque home screen and click on bottom Left Hand menu, then select Vehicle Profile then edit the profile you already set up for the Pajero. Scroll to the bottom and select the protocol where it says "Automatit - through profile scan" and change to
ISO 15765-4 CAN (11bit 500k baud)

Now when you add the transmission temp to a screen you must use:
Transmission Temp (Chrysler/Dodge)

I think the "f-50" is for the Aisin transmission, and the Jatco should be "f-40". Once you have it set up and working, first thing in the morning before you actually start the engine, turn on the ignition and wait for all your readings to come up. Intake air, coolant and transmission should all be the same temp, within maybe a degree or two. If the transmission temp is more like 10 degrees different, use the other number.

Belated thanks for the info...

I just found out you can get torque pro to work on Android auto.
Need an API and be in developer mode in AA.

This dongle I have seems to be rubbish however, still throws a/t fault codes, and today it made a bunch of lights flash on the trip computer above the head unit and the door open indicators flash on and off. I think I might have to invest in something a little better. Any suggestions?

Thanks in advance.

A couple of things. Make sure you select 11Bit 500k baud and also make sure you dont click faster communication in settings. These will throw codes.

EGT sensors for 3.2L Diesel

Yes, it is possible to read the 3x EGT sensors on 3.2L 4M41 Pajero with the active (closed type) DPF system (but not on the passive (open type) system as they don't have sensors).

I set about finding these by writing a simple app which continuously monitors a set of PIDs and highlights changes in their values. After applying a blow torch to one of the EGT sensors, I saw a byte in one of the responses begin to rise in value and then fall when the heat was taken off. This technique of scanning the CAN network and then applying heat (or some action) while observing changes is nothing new.

So that I could derive the formula, I compared this raw byte value to that of ‘Cat B1S1’ reported for the same sensor on the standard PID set. (Side note, this ‘Cat B1S1’ sensor is EGT #2, or the second EGT sensor downstream.) After a few drives and comparisons, I was then able to figure out the formula to convert the raw value to degrees Celsius.

The EGT sensors and their Torque configurations are as follows:

Long name: Exhaust Temperature (EGT #1)
Short name: EGT #1
Mode and PID: 2110
Equation: (A-40)*5
Header: 7E0
Min value: -200
Max value: 1075
Scale: x1
Unit type: C

Long name: Catalyst Temperature (EGT #2)
Short name: EGT #2 (Cat)
Mode and PID: 2110
Equation: (B-40)*5
Header: 7E0
Min value: -200
Max value: 1075
Scale: x1
Unit type: C

Long name: DPF Temperature (EGT #3)
Short name: EGT #3 (DPF)
Mode and PID: 2110
Equation: (C-40)*5
Header: 7E0
Min value: -200
Max value: 1075
Scale: x1
Unit type: C

The first EGT sensor (EGT #1) is located in front of the Cat, the second sensor (EGT #2) is in the middle of the cat and the third sensor (EGT #3) is just after the DPF.

The readings are accurate to within 5c.

During a DPF burn, I saw these sensors sustain values of EGT #1: 450c, EGT #2: 690c and EGT #3: 625c, as expected.

These Torque configs have been tested on a 2007 NS and a 2018 NX (both 3.2L Diesel Auto with DPF).

Yes, it is possible to read the 3x EGT sensors on 3.2L 4M41 Pajero with DPF, as these models have the sensors in place.

Thanks for that. It will be very useful if I decide to do a DPF delete and need to work out the correct resistor values for the sensors

You mean EGR delete?

G’day Mate,

Like you I invested in a cheap OBD2 scanner and found a few issues with using it. I purchased an OBD2 Bluetooth scanner from OBD2 Australia cost $39 and found that it works with Torque Pro and Car Scanner really well. No errors and I could pick up all the sensors I want.

For your consideration.
Kind Regards,

Tonks

I think on average people who bought cheap ELM327 BT OBD2 scanner for $10 or so from amazon/ebay/aliexpress are not satisfied with it. My first one is crap but second one is gold. Been using it for one and half year with no issues and takes seconds to connect to my Torque Pro. BTW my Torque Pro is installed in an old Galaxy S5.

No, I meant DPF. I was referring resistors to replace the DPF temp sensors. I have since seen the resistor value confirmed on another post if I do go that route one day.

Is this thread still alive?
