  • Torque Pro Auto Temp PID's for 120 Prado 2008 3.0 D4D auto

    Hi all, just thought I'd share my experience with using Torque Pro on an Android device to display auto transmission temps.

    I'm using a Joying 5.1.1 double DIN head unit, which so far I'm reasonably happy with. Torque Pro came preloaded on it. I ordered an ELM327 OBD2 Bluetooth adapter with the head unit. The first one didn't work properly, and after a few emails back and forth Joying sent me another one, which so far is working fine. I have to say I've been reasonably impressed with Joying's desire to offer good customer service. They're not always that easy to understand, but they seem very anxious to be helpful, and usually respond fairly quickly.

    So I've got a 2008 D4D 120 GX auto. The info on the interwebs wasn't always that clear on which formulas to use for the custom PID's for auto trans temps. Eventually, after trying several versions, this is what worked for me:

    Auto Oil Pan Temp:

    OBD2 Mode and PID: 21D9
    Long Name: Automatic Transmission Oil Pan Temp (or whatever else you'd like to call it)
    Short Name: ATF Pan Temp (or whatever else you'd like to call it)
    Minimum Value: 0.0
    Maximum value: 120 (or whatever other value you'd like for the top temp on the gauge. Some threads suggest 160, but I've got no intention of letting my tranny get that hot)
    Scale factor: x1
    Unit Type: C (for Celsius)
    Equation: (((((E*256)+F)*(7/100)400)/10)-32)*(5/9)
    OBD Header to use: left blank

    Auto Torque Converter Temp:

    OBD2 Mode and PID: 21D9
    Long Name: Automatic Transmission Torque Converter Temp
    Short Name: ATF TC Temp
    Minimum Value: 0.0
    Maximum value: 120
    Scale factor: x1
    Unit Type: C
    Equation: (((((G*256)+H)*(7/100)400)/10)-32)*(5/9)
    OBD Header to use: left blank

    This is what worked for me. There are some threads around that suggest a PID of 2182 instead of 21D9, and some threads have A/B or C/D in the formulas instead of E/F and G/H. Couldn't make it work with those.

    When you're driving along you'll observe that the TC temp varies a lot more quickly then the pan temp, especially when accelerating, going up hill, or using the gears for engine braking. When you return to flat steady speed driving the TC temp usually equalises to the pan temp quite quickly.

    Hope that's helpful to someone :-)

    Hey Tim,
    Cheers for that. I did have Trans temp, but it showed the same temp as coolant.
    Shall try it soon and post.

      Hi Tim, how do you find the sound quality from the unit as well as the speed?

      Are you using the factory speakers or better?

        Hi Killswitch, sorry for not responding earlier - I've been overseas. I find the sound quality fine, using the factory speakers, but I'm not much of an audiophile, so I expect I'm more easily satisfied than some :-) The std app for listening to music is fairly basic, though - it would be nice to have a better interface than Joying provides. I think I read somewhere that others have managed to install better apps for it, but I haven't bothered. Tim.

            Hi all, I have 01/08 D4D. My readings display as zero on both custom PID's. Any suggestions?
            I have tried changing the letters in the equation as Tim suggested but nothing.
            The only other trans temp PID equation I can get to work (method 3) only shows the same as coolant temp.
            Thanks, Wayne.

              Thanks very much for the info Tim. It appears to be working OK on my 2005 V6 Grande.
              Are they any other useful PID's that anyone's aware of?
              Cheers
