Anyone know the PID for trans temp?

Hi all. I run a scangauge on my 80, but I bought a Bluetooth module to check some codes on my sons bronco. For fun, I put it in the LX570. This is the car we tow with, so I'd love to get the trans temp. I've scoured the net for the Toyota PID for the custom gauge but I can't seem to get one to work. Any one know the PID or a link to find it? I'm using an app called OBD Fusion on my iPhone. Thanks.

I just started using this one yesterday in the Torque app. Seems like the correct one.
Pid 2182
Equation ((((A*256)+B) * (7/100) – 400)/10)


Sent from my XT1254
 
Do you recall what you put in for the OBD Mode? or Module/Header? Thanks.
 
Thanks, I'll try it later today.
 
i've never had the chance to use the torque app as my understanding is that it is only for android based phones. it looks pretty nice, but i limited my search to iOS apps.
 
Just back from a long trip - sorry for the tardy replies. Yup, Torque seems to be a good app. I used it during the trip and was satisfied. Primary reason for setting it up is to monitor temps while trailer towing.
 
Does anyone have access to any other additional codes aside from Transmission Temp? I used the transmission temp PID from scangauge (TXD 07E02182) on with the EngineLink app on my 2013 LC with a generic wifi ELM327 reader today and can confirm it works, but I wanted to see what other info I could gather.

Toyota/Lexus/Scion Specific : Linear Logic : Home of the ScanGauge

For reference I imported the FRZ/BRZ Oil Temp code as well (TXD 07E02101) and that does report a value, but I don't think it's really oil temp on the LC. I suspect this because the intake air temp was 71F and the oil temp code was reading about 70-72F as well but would drop as low as about 41F and would move up to 90F+ and then drop back down over a period of several seconds every so often even at idle. The Transmission Temp (Alternative) value (TXD 07E12182) reports nothing, FYI.
 
I am trying to get this to work with OBD Fusion and am not sure what I am doing wrong. It will not allow me to leave Module/Header blank. it defaults to ECM. Could someone that has it working screenshot their settings page.
Thanks a bunch

In EngineLink I just split the ScanGauge TXD field and set the Header to 07E0 and the PID to 2182. It didn't require any other special settings except the formula.
 
here's a screen shot for my ATF data:

I may have to get a different scan tool. I got the Carista one because it works on Bluetooth problem is only works with their app or Obd Fusion so I can't try engine link.

Plan to tow our boat frequently this summer so I would really like to keep an eye on this.
 
With the above settings, when I hit test it says reading then changes to "No Data Was Received"
 
May have just realized the obvious issue. It has the new 8 speed tranny so I suspect codes are different.
 
Well it's been a day over a year since posting on this. Has anyone else purchased the optional PID's now available from OBD Fusion specific to Toyota. There is an incredible amount of info available including transmission temp. Very much worth the purchase price. Curious to see how those with much more knowledge can put all this available info to work.
 
I cannot speak to Torque Pro, but I am able to read both the torque converter and the pan temps in EngineLink. I suspect if you google a bit you can find how to convert the formula that EngineLink uses to the one that Torque Pro uses

From Towing with a 200-series Toyota Land Cruiser

Gauges
The last upgrade I made (and highly recommend) was to purchase an ELM327-compatible Wi-Fi OBDII reader ($15-20) and the EngineLink App for iOS ($6). When towing I insert the reader into the OBDII port and connect my iPhone to the CLKDevices WiFi name, then fire up EngineLink. Based on a number of other threads I read, I added two additional gauges in order to be able to monitor the automatic transmission pan and torque converter temperatures while towing:

  • Toyota A/T Pan Temp. PID 2182. Formula ((((A256+B)(7/100)-400)/10). Range -40 to 300. Units are F.
  • Toyota A/T TC Temp. PID 2182. Formula ((((C256+D)(7/100)-400)/10). Range -40 to 300. Units are F.

Note that the "Trans Temp TBD" is the torque converter temp above. Yes it shows the same as the transmission in this shot, because I was cruising on the highway in 4th gear at 70mph. But the values do diverge when the TC unlock and/or you're idling/accelerating around town. Highest I've seen the TC was closing in on 240F when I was cresting 10,000' in Grand Mesa... pan temp was about 225F
 
Thank you for your detailed post, I have read your other ones as well.

For some reason PID 2182 is a non starter in TP. I have spent several hours googling Trans temp PIDs and tried them all out to no avail. I wouldn’t think this would be that hard.:bang:
 
With some experimentation and I’m not sure if this is correct as I did get a rising temp reading.

PID 2182, unit type F, equation A+40. I will test further this afternoon.

So I ran around a bit mostly local. Trans temp got as high as 160 degrees. It’s 40 degrees here.
