Can ODB or DLC be used to monitor real-time temps?

[MICA4R]

I was flying on Southwest the other day and say an ad for a bluetooth ODB in the SkyMall Mag that can hook up to an Iphone and give read outs of engine oil temp. Transmission temp, Coolant temp. O2 readouts and some other stuff. Has anyone bought this, or know if this is even possible... I'm usually very skeptical of SkyMall stuff.

Welcome to Land Cruiser Owners On Line
Based on this link it seems like the DLC or ODB (I'm using these interchangeably) can be used to give us lots of useful information about our rig.


This would be SWEET if we could figure out a way to tap into that data!

I don't know about that particular product but on my 2010 Ford V10 Motorhome I have one of those new EcoRoute OBDII modules that send all that data and more to my Garmin 1490LMT. It is sent via bluetooth, so no wires are dangling. I haven't used it yet because it hasn't been RV weather since I got it last month, but it is reviewed favorably.

You probably know about the Scangauge II. I really like mine. It is plugged into the OBDII port and I have programmed some additional codes into it.

YES!!! I just recently bought a bluetooth transmitter off eBay for $35 (ELM327 is the model) and hook it to my HTC Incredible (Android 2.2) using an app called "Torque" which is $4.99 and it delivers real-time data of anything you want, including speed, throttle position, RPMs, coolant temp, intake temp, etc.

It will also log data, show graphs, different dials, and even show and clear error codes.

Are you guys able to get tranny temps on that?

Ordered mine about a week ago, still waiting on it to arrive. A buddy of mine had one in his MDX, it's pretty cool.

I just ordered mine as I already have the Torque app and it shows you can add Tranny Temp, now I hope the ODBII scanner actually reports that information.

got my ELM327 shipped for $29 bucks from Gadgettown Gadgettown.com - Buy Best Electronic Gadgets, Laptop Parts, Computer Components, Cell Phone Accessories!

and used the paypay pay me later option for the first time and got $10 bucks back so $19 bucks! Cant beat it.

I purchased the Ultra Gauge and love it.

UltraGauge Automotive Information Center and OBDII Scan Tool

I gety lots of data that the normal readouts do not give.

Now to answer the questions:

No tranny temp, no oil temp.

Though lots of data on intake temp, cat temp and throttle position, the T4R does not have the necessary sensors to relay this data. The ability to read this data is in the Ultra Gauge, but no sensors to transmit mean no available information for display.

Recommendation:

Purchase the Ultra Gauge and utilize what info you can view. I like the engine load data as well as data on oil and fuel mileage.

There are 2 Transmission sensors that read temp in ohms.

I just have to figure out how to tap into them.
Please do share if you know how.

Using a ScanGauge II with the X Gauge feature seems to be the only way.

 

[DC runner]

I use a OBDII adapter and the torque Andorid app. I have real time access to all information (Trans, engine temp) real mpg.. etc etc
As well as full time mapping and tracking via GPS. I can see, over a trip, overlaid on google maps where my engine was X or my trans was X.

My buddy had a scan gauge and dumped it as soon as he saw mine.


If you have an android phone, you have a device with about 100 times the cpu power of the scan gauge. All you need is the physical connector to the OBDII.....

Is exactly what I bought. Only from Amazon. Too lazy to find it on there. It works perfectly. All it is, is a OBD to Blutooth convertor. Your phone app (torque) for android does ALL the work.

Did you have to get the Toyota specific Android app for it to be able to read tranny temp? I have one but haven't tried it yet, didn't think I would be able to see much on the little phone screen. Also, I can't leave the phone on all the time, since it's been around 115 here every day the battery in the phone gets too hot and it shuts off after 15 minutes or so. Since I want something I can leave in the car all the time that will work without fussing with it a lot the phone isn't really an option.

Do you have a v8?

If you have a v6 can you let me know the code for the trans temp.

It works if I use it on my friends ford and then plug it into the 4R but it doesnt show trans temp if i do a direct plugin

.............


1) There are two temperature sensors in the 09 AT, "A" and "B". They read the oil temperature, as one would expect
2) The sensors present the temp as an electrical resistance to the ECU, varying from 79Ω to 156kΩ and the ECU converts it to a temp value in °C
3) The Toyota Techstream tool reads the temps from the ECU through the OBD interface, so it must possible for us to do so, too!
4) The ECM speaks ISO 15765-4 (and possibly SAE J1987, they're both mentioned in the manual)
5) The "B" sensor is placed directly before the oil cooler inlet pipeline, not mentioned where the "A" sensor is
6) The ECU considers the valid temperature ranges to be -40°C to 215°C (-40 to 419F)

I tried the Bluetooth OBDII adapter with the Torque Andorid app and it's pretty useless! Since I can only get 2 gauges on the screen at a time it won't display much but then most of the options don't work anyway. I was able to display Coolant Temp and RPMs but the others didn't work, not even Voltage and there's no option for tranny temp. The Diag My Toyota app does display tranny temp but that's about all it's good for since you can only display one value at a time. The phone battery will only last about 2 hrs running the app so it's not good for checking very long.

What kinda crappy phone are you using? Those are literally the EXACT opposite results I have.

You can set up tiles and have about 9 or 10 different things at once. You can also move between screens, with different tiles, pretty easily. You can see real time info of everything.

You need the pay app though. The free app is just a demo and doesn't give everything. You also need to get the torquescan addon. Did you read the wiki instructions are just fritz with it and move on?

Here are some screen shots. I can literally see everything.

Edit: You can see I can also see instant timing advance. That one I love seeing. I can see a difference between 87 and 89, in terms of how far it advances. On 87, I have seen as much as in the 20's when climbing a hill.

Kinda neat to see.

 

[DC runner]

Ok. You can have 6 tiles on each screen, and as you can see, you can move to a different screen sideways. Like in android.

I also show you the raw data screen, called Torque scan, that simply lists all the data it is getting.

It lists everything. Temp of Air, MPG (instant and calculated), Trans Temp, Coolant temp, co2 in exhaust, a ton others I don't use. Lots of voltage values for various sensors.

I have a 2005 v8. Sport. Perhaps user error?

Also, two hours? I have an old android phone (evo) that sits in my truck. Off. If it is hot, I pull the battery out like I was also told to do. Then, when I start up the truck, I turn it on and off we go.

I have this magically invention commonly refereed to as a "phone charger" that I have to plug the phone into on long trips... I believe the dark magic seller at the walmart sold it to me for about 10 bucks.

I kid. My point is, not sure but you should check your settings or read the APP wiki.


Edit: What are your settings? 1. Enable faster communication. The wiki states you need to, to enable faster data polling. If you didn't then you will only be able to read some data, as you are going too slow. I found that by reading the wiki instructions.
2. Enhanced MPG. Set ON.

Those are my only really important settings.
I have only ever used this with this. I found this app in March when I had a check engine light pop. Used it to determine a o2 sensor. replaced and cleared. Used the DEMO for that. Started to tinker, paid the 4 bucks for the full app and downloaded Torque Scan for free addon. I also allowed the APP to scan my car for extra PID's (sensors). Allowed it to do this one long trip. Took a LONG TIME.

That is all I did.

 

[MICA4R]

any V6'ers willing to share their codes?

still can't get a trans temp on the V6 with TORQUE app on HTC evo

 

[MICA4R]

bump...

 

[DC runner]

Give me a bit. Weekend and all! I just had to wipe my phone, so I am gonna tinker today with a starting from scratch to see if any thing I had to do.

I will get back to you.

 

[DC runner]

Ok.

From a dirt scratch phone that was wiped of EVERYTHING and re installed. This is exactly what I did, and was, once again able to access Trans Temp Method 2 instantly.

1. DO not USE the DEMO. I haven't used it since march, but yea, it is severely limited and only allows 2 tiles per screen. The APP maker obviously wants you to support him and buy the paid app.
Buy it. You have 24 hours to refund it. Buy it and try it, if you hate it, refund it.


2. Once you have the paid app. SET UP your profile. Go through a set up your OBDII adapter, make sure "Fast communication" is on.


3. Go to realtime information at the main screen of the APP. Hold on one of the tiles, delete it, and then add a tile. It will then give you a scroll screen on available data to track. All the way down, in the T's (it is alpha) is TRANS TEMP method 1 and 2. I do not have method 1, although I hear it can be manually found with a manual PID. I see Trans Temp method 2 immediately and see the info.

ON this screen it is in C, but if you click USE Fahrenheit in the options, it will convert it on the tile.

And wham. That's all I do.

If you want it to log that data, go to data logging and select PID's to LOG and ADD Trans temp. Restart the app, and it will log that for you.



Final note: 2005 and beyond went to the same trans for all trucks, right? The sealed 5speed? That should mean it should work? I have an 05, v8, sport.

That may mean that those with the non-sealed 5 speed and the 4 speed on the v6's will not work and for that, sorry.
