Trans Fluid Temp - ODB2 Adapter

Hello

I’m trying to check the Trans Fluid Temp on my 2014 Impala LT Limited. I got a Mini ELM327 2.1 blue tooth adapter. It came with Torque Pro1.8.16 9/16/2014 as well as some other ODB2 apps. Got it working on my Android phone but it doesn’t show many temps ie. Transfluid, Oil or Outside temp. It already has them listed in the Manage extra PID’s/Sensors but I also tried to add them with the Add Predefined Set >Pontiac/GM/Opel/Vauxhall which made no difference. I went thru the process of adding the gauges and when the car is running, nothing shows.

On each of the temps I was trying I used the Test option for each and it came up No Data. I tried others like Oil Pressure and it showed the result.

Here’s the PID’s the system defaulted which is also the ones I’ve found on this site:

Trans fluid temp 221940 Equation A-40 for both method 1& 2. Header Auto & 7E2.
Oil temp 221154
Outside Air Temp 221161
Oil Pressure 221470

In the list of sensors while car running or with ignition on, doesn’t show oil or trans oil temp but shows Ambient Air Temp.

Any ideas why it’s not showing or returning data for the Trans fluid temp?

Thanks

It might be because you're using an ancient version of Torque Pro (which probably isn't even a legitimate version - it's most likely a pirated version).

Spend the $5 and buy the real version. Besides supporting the author, it will probably work a lot better. :-)

Trans temp definitely works on the 2012+ Impalas with Torque Pro - I've used it many times.

It could also be an issue with the specific OBD-II adapter you purchased too (they are not all created equal).

For what it's worth, I'm running Torque Pro 1.8.106 (many, many, many versions newer than 1.8.16!) - released on 8/30/16.

I hear what you're saying but the video's I watched on Torque Pro were from 2014 and showed the trans oil temp so you'd think the 2014 version would work.

I bought the current Torque Pro App and same thing, none of the temps show as well as no data returned from the test options.

I tried clearing the list of custom pid's and re-adding the GM ones. Still nothing.

The list of Available Sensors the ECU reports doesn't include anything from the transmission and seems it only reports the basic odb2 info from my old ODB2 scanner from 2007 & older. No ABS.

The ODB2 protocol shows ISO 15765-4can11/500.

Do you have a link to which OBD-II adapter you are using?

If you are selecting the GM-specific transmission temp PID (either "Transmission Fluid Temp (GM Method 1)" or "Transmission Fluid Temp (GM Method 2)") when adding them to the Torque display and they are not working (with the current version of Torque Pro), then I'd have to assume that it's something with the specific OBD-II adapter. Like I said, I know that it works with the computer in the 2012+ 8th gens.

I'll have to check mine to see what protocol it picks - it's been a while since I used it.

The connection to the adapter works fine. I get all the regular odb2 stuff I used to get with my old scan tool, coolant temp, rpm, oil pressure. When I go into the pid section and edit the 2 trans fluid temps you mention, there's a test option and those along with many others come back with no data while the oil pressure, coolant temp come back with a value. Also when I add the gauge I get no value. I don't actually save anything in the edit function, just use the test option.

It seems like there's some extended GM functions that need to be accessed. The ECU doesn't report anything for the transmission in that section of Torque. It could certainly be the adapter I have but there must be some protocol you'd need to have to access those sensors. Most of the ELM327 adapters mention they handle many other sensors. Maybe to read the other temps require an adapter with a special protocol.

Torque shows pids for injectors but none of them work either. That would be cool if you had an injector problem it would show.

For what it's work, Torque Pro is using the same OBD Protocol on mine (ISO15765-4CAN11/500.

A few other things I saw in the Adapter Status section of Torque Pro:

Adapter Version: ELM327 v1.5
Faster Communication is enabled and working on my adapter
Trans temp is NOT listed in the "Available Sensors" section - probably because it's an "Extended" PID that you have to add. It definitely works though.

Here are a few screenshots that show it's working:

Thanks for taking the time to post pics. Torque Scan is an add-on. I'll have to load that and let it do the scan and see what it finds. Some said the scan takes a long time, half hour or more. Don't know if you need the car running or not.

Do you have the name and model of the adapter you have? Mine is ELM327 mini v2.1. I read some reviews on mine and some didn't want the 2.1 but preferred 1.5 as it's more compatible.

The PID's I used for trans oil temp are the same as worked for you.

Thanks

This is the one I purchased - I love it's tiny size, black color and the fact that it has an on/off switch... $16 shipped on Amazon right now...

Interesting the first review is yours.

I installed the Torque Scan. On all the temps I've been talking about 'No data' is returned. I then did the pid scan. There's 2 options, regular and extended. The regular took 15 min and the extended has a note it will take a very long time so I didn't do that one. The scan didn't find anything.

I wonder if something is turned off in the ECU that allows these pids to be returned or if they're available all the time.

The company I bought my adapter from offered to give me a refund. Outstanding company. Maybe they know something I don't about it.

Maybe I'll try the one you have. For the free shipping I need a $50 order. Yours mentions Canbus. Don't know if the ISO15765-4CAN11/500 means canbus or if the canbus circuit just isn't working.

I'll let you know when I get another one and how it works.

Thanks

Actually both versions of Torque Pro I have, 1.8.16 & the latest 1.8.106 have the pids already included the GM Trans Fluid Temp pids in that custom pid section. All I need to do is add a gauge then select the GM trans fluid temp or go into the pid and select edit then click test to see if it works. Don't seem to need to add anything. I did try clearing the list then re-add the GM pids with the option to do so but it only puts the same ones out there.


Did try that speed up option Faster Comm you mentioned.


Thanks

What I meant is that if you go into "Adapter Status" and click on "Available Sensors", the GM-specific transmission temp PIDs don't show up there, even though I added them via the Settings->Manage extra PIDs/Sensors menu (as you did)... I'm assuming that menu option only shows the "standard" PIDs that are "available". Was just something that I noticed - even though I can add gauges for those PIDs, they didn't show up in "Available Sensors" list via the "Adapter Status" icon... The GM Trans PIDs worked on mine when I went into the PID, selected Edit and then clicked Test - so I'm getting completely different results that you are - and the only difference is the OBD-II adapter being used.

I have a feeling the problem is with the 2.1 version of the ELM327 standard that your adapter is using... Most ELM327 adapters use v1.5. You'd think that version 2.1 would be fully backward-compatible, but obviously not...

There is nothing else that you do via Torque Pro to make the PIDs work. It has to be an issue with that specific OBD-II adapter that you are using.

I agree completely. I watched a youtube video from early this year and the person mentions not to use the 2.1 as it's less compatible than the 1.5.


I looked at some of the adapters Torque recommends. One of them has several models but only 1 supports AW-CAN which may be what is needed to report extended sensors. The have a comparison chart.


This is the one Torque recommends but doesn't support AW-CAN
https://www.scantool.net/scan-tools/.../obdlink-lxbt/


Here's their better model that does support AW-CAN:
https://www.scantool.net/obdlink-mxbt/
This place has software options that almost give you a Tech 2 device but you'll spend a total of $300.


The adapter you have mentions CAN-BUS. I wonder if that's AW-CAN? Maybe they can tell me if the one they're currently selling will work with Torque & Trans Fluid Temps.


Thanks

We know that the one I linked to works with the GM Trans PIDs. It's still the exact same adapter that I purchased (says v1.5 right in the main description). I would just order that one since it's inexpensive and we know that it works (plus it's nice and small and has a power switch). The OBD-II port on the Impala is in a location where a real long adapter would get in the way of your let when entering and exiting the vehicle, so getting a real small OBD-II adapter is nice.

The OBD Link LX doesn't support CAN. If you have a GM made after 2007 or 2008 it will not work for you.

I own the OBD Link MX Bluetooth version. I don't believe the OBD Link MX WiFi version works with Android.

It's worth noting that the ECM in my SS freaks out and stops commanding the alternator to charge if I leave the module plugged into the J1962 OBD port through an ignition cycle.

If I plug it in after I start the car... the OBD Link MX is one of the most reliable fast interfaces I've tried for Torque Pro. It will let Torque Pro read the Transmission temp in my 2009 SS.

Only reason I question yours from Amazon is it was 3 years ago. I read a lot of reviews where adapters that said 1.5 in the description ended up being 2.1 when the customer got them resulting in very unhappy customers. Who would think a newer version would be bad. I'm trying to find out from them if it is still the same.


Thanks
