How can I read the transmission temperature on my 2012 Dodge Durango 5.7L Hemi via OBD2 (a wifi adapter - using Torque for Android and DashCommand for iOS)?

  • Note that for Apple devices, you need a Bluetooth ELM327 dongle, not the WiFi version. – PeteCon Sep 3 '16 at 11:09
  • Actually, in iOS you need a wifi adapter while Android supports both – Rob Sep 3 '16 at 18:16

According to this forum post, you need to do the following:

Open up torque on your android device On the main screen hit the settings button (gear shaped button) -settings -manage extra PID's/Sensors -hit the menu button (mine is the three dots on the top right) -add predefined set -chrysler/dodge/jeep/mercedes

Three PID's will come up. I just deleted the two I dont need. There is one for <2012 jk's and 2012+

BOOM!

Have to be in gear for it to pick up, otherwise it reverts to coolant temp. The PID is programmed to read Celsius and I edited it to F but thought it would throw off the calculation so I changed it back, deleted the gauge and re added it and it reads in F now like the rest.

A few entries down, there is also this post about what you need to insert if it isn't already there:

OBD2 mode and PID      2130
Long Name              Transmission Temp (Jeep 2012 and later)
Short Name             Trans.Fl.Tmp
Minimum value          0.0
Maximum Value          200
Scale Factor           x1
Unit type              °C
Equation               L-50
OBD Header             7E1
Diagnostic start       -blank-
diagnostic stop        -blank-

I'm sure one of the two methods would work for you.

  • @SteveRacer did it work on your Durango? – Rob Sep 3 '16 at 18:17
  • They are registering at 0 on my Durango. – Rob Sep 3 '16 at 18:19
