    So finally getting back to this. Tried the 2 forumulas that you tried, and doesn't appear to work.
    Got this from the log
    [2021-09-29 13:37:57.141449] [0x91362140] [error] [OpenAuto] [ObdGetPidValueFunction] empty values, query: 21d9
    [2021-09-29 13:37:57.141798] [0x91362140] [error] [OpenAuto] [ObdManager] gauge evaluation failed, formula: getPidValue(10), what: Unable to parse values for PID with query: 21d9

    seems like it doesn't get any values from 21d9

    Anyone have any thoughts on what to do?

    @noelk were you ever able to get your fuel mileage working?
    I'm wanting to do something similar but wasn't able to get it to work.

    I'm hoping to get an average if possible, but would settle for current fuel mileage if possible.

    Just bumping this, hoping that someone might have some idea on how to get transmission temp read.

    Would also like to figure out how to display an average MPG if anyone knows.

    hey chris, like you i got off on other projects. The mpg formula keeps giving me an error, something about an empty cell. so no love. I think once we get the realtime mpg working the average would be possible as well. Where are all those math wizards. I think the formula is correct but the program cannot compile it because of syntax.
    All the nissan and toyota forums are full of people trying to get that trans temp. The torque app forum has a lot of ideas but no one seems to be able to communicate with the sensors.

    Yeah, I tried that exact same things with both the free torque app, and the paid Torque Pro version.

    I got nothing with the free version, but the paid worked.

    I've attached screenshots of my PID editor setting in the Troque Pro app.

    Anyone know what the battery voltage PID would be?
    Torque can read it, but I'm not sure how to get the PID from that app, to use in OAP.

    Also, is there a way in OAP to set a threshold upper and lower limit?
    Meaning, for charging voltage. set a low and high warning? for example: if it drops below 13v or above 16v it starts flashing?

    So I have Torque now, and able to add a dashboard for trans temp to it. Seems to work, but is there a way to tell what PIDs the display use?
    I can't seem to find it. Would like to try whatever it's using in OAP.

    I would really like to get the following readings if possible:

    Trans Temp
    Charging voltage
    Fuel rate (to use for calculating MPG)
    TPMS

    Does anyone have any thoughts on codes/examples to try for a Toyota in OAP?

    Edit: jhornbr225 how do you get to the details of the PID like you have in your screenshots from Torque? I have Torque pro now, but don't see how to get the details like you have.
    Also have you ever gotten these to work in OAP?

    I googled and found a forum that was discussing those trans temp PID's, can't remember which one now.

    I have not installed an OBD reader to to my Pi, and it's still on my desk, anyway.

    I think I got the Transmission temp working, it's a totally different code than I've seen previously.

    [ObdPid_9]
    Query=01b4
    Formula=a-40

    [ObdGauge_9]
    MinValue=0
    MaxValue=250
    Limit=200
    Formula=(getPidValue(9)*1.8)+32
    Label=Trans Temp
    Precision=0

    In torque they have a preset trans temp gauge. The value between this and that, seem to be the same. So I think it's working.
    Question: What does 'Precision=0' do?

    Next question:
    Does anyone know how to get the battery/charging voltage?

    I thought it would be this one. but log shows no data.
    [ObdPid_10]
    Query=0142
    Formula=(256a+b)/1000

    I know I can get a reading for charging, since Torque can display it. but I can't figure out how in torque to see what it's using for the gauges. Anyone know?

    I think this means the value is without decimal places also a integer.

    I don't have a new enough vehicle that offers as many OBD2 PIDs as your 4Runner, but I've used OBD Fusion on my tablet to read codes before and it does show battery voltage.  However, according to this Wikipedia page, there is no code for battery voltage which leads me to believe these tablet apps are just reading the input voltage of the OBD2 reader.
