Hello all

I'll be doing some towing with my new-to-me '09 LX. I'd like to be able to monitor tranny temp as I go, particularly on the up-grades.

I'm looking into pairing the VEEPEAK OBD2 scanner with the TORQUE PRO android app, and I understand from this third-gen thread that it is possible to set up a custom PID for this as follows:

OBD2 Mode and PID: 222201
Long Name: Transmission Temp F
Short Name: ATF Temp
Minimum value: -40
Maximum value: 300
Scale factor: x1
Equation: AA*(9/5)-40
Overrides PID: "Does not override any PIDs"

What I am not clear about is whether this information is correct for the 2nd Gen Pilot. If there is anyone out there who has experience with this, I'd love to hear from you.

Thanks everyone!

Alrighty then.... I'll answer my own thread in case it helps anyone else.

I got the VEEPEAK OBDII scanner as threatened. Apparently it is one of a number of scanners that uses the ELM 327 protocol and/or microprocessor.

I got it to show tranny temperature with the TorquePro App (Android for me), but not before trying out a number of different initialization strings. Apparently some strings work for some people but not for others, and I still don't know if it has something to do with the particular OBDII scanner or the particular ECM in your vehicle.

In any case, ath0 worked for me, as is did for TheHawke (see his post of May 17, 2017 on the Torque forum). The information on HOW to set the init string came from post #16 of this forum.

So, to summarize:. After you figure out the basics with setting up a profile for your Pilot in TorquePro & getting it to talk to the OBDII scanner, set up a custom PID:
Gear Icon | Settings | Manage extra PIDs/Sensors | Ellipsis | Add Custom PID. Then enter the following.

OBD2 Mode and PID: 222201
Long Name: Transmission Temp F
Short Name: ATF Temp
Minimum value: -40
Maximum value: 300
Scale factor: x1
Equation: AA*(9/5)-40
Overrides PID: "Does not override any PIDs"

Then back to
Gear Icon | Settings | Vehicle Profile | Edit | Very Advanced
and enter the correct init string

ath0 worked for me
atsp7\natshda1df1 worked for someone else (note that the \n is a line separator)
ATCAF1 can be tried when all else fails (including just leaving it blank)

I only took one screenshot of my test-setup so it doesn't show much. This photo is right after startup. I found that usually the Coolant temp goes up much faster than ATF temp when warming up, but once at operating temperature, the Coolant temp stays relatively constant while the ATF temp moves around more depending on how hard the tranny is working, although even then it moves sort of slowly. This is to be expected, so I think all is well.

This also works for Honda Pilot 2018 on Torque Pro

OBD2 Mode and PID: 222201
Long Name: Transmission Temp F
Short Name: ATF Temp
Minimum value: -40
Maximum value: 300
Scale factor: x1
Equation: AA*(9/5)-40
Overrides PID: "Does not override any PIDs"

The set up info to monitor Transmission temp with VEEPEAK is valuable, sticky worthy info. Since we're going into summer, I thought I'd pull it up, if anyone is interested.
Look up 👀☝

Yes, this worked on my 2012 Honda Crosstour EX-L V6 so it should work on 2nd Gen Pilots.

Is that using the Torque app on your phone, connected to a Bluetooth OBD2 scanner?

Cool, then I've got to try that. What temperature range are you looking for as ideal?
Going into the heat if the summer, I hope I can stay below 190°F. This will be my first summer monitoring how hot it gets. We're just not taking those long trips as often as we used to since the pandemic. Video calls are changing the world.

I hear you. I used to try to cleverly plan to combine chore trips to save time and gas. Now, I spread them out not only to avoid the risk of cross contamination, but also to give the Pilot a regular opportunity to warm up, lube up, burn off some carbon, and keep those tires from going square. Enjoy the cheap gas while it lasts. :)

I burned WAY to much time trying to find an iOS app that would provide this information. I have the ATF and PS cooler added, regularly tow my 3,800lb (dry weight) travel trailer, and have been wanting to monitor my transmission temp. I found several threads on the details of the Torque Pro app for Android, but nothing for iOS. I hope to save others from the rabbit holes of research and troubleshooting that I dug into. First off, I found an app that works and successfully now have the Temp displayed on the dashboard on my phone now.

App: Car Scanner ELM OBD2 (free version). Works with BT and WiFi.
Scanner: Foseal OBD2 scanner (WiFi version, since it was cheaper and I wasn't sure that I'd use it). It works, but in retrospect, I'd prefer a smaller one that I could leave in and not have to worry about breaking it when I push down on the parking brake.

App setup is key. The complicated custom PID formulas found on other forum threads are not required. All that's necessary is to chose the right connection profile (Honda OBD-II/EOBD + AT (CAN)) found under the Settings menu. After that, when you scroll down the list of available sensors, you will find ATF Temp F available to be selected.
