I'm not familiar with this software, but each ECU can have totally different PIDs. I saw another post that it should be hex D9 (decimal 217, but it's probably entered in hex) and it should use E and F instead of A and B on the pre-09s.

 

As @BillG suggests, try E and F instead of A and B and use D9 (or 217) for the PID number. This is what I use with both Torque (Android) and Car Scanner (iOS) and it matches what one would see with Techstream for my 2007. My notes say that it is good for pre-2010 Toyota and we have the same transmission, so I think it should work for you too:

Header: 0
PID: 21D9
formula: ((((E*256)+F) * (7/100) – 400)/10)
Min value: 0
Max value: 300
Name: ATF or anything you like
Unit factor: F

I am pretty sure that the Sienna only has one trans temp sensor (in the pan?).

I have a 2010 and I've always been frustrated that there was PID information referring to "up to 2009" and "pre 2010". I could never tell for certain if it originated from Toyota's internal reference to production dates as opposed to actual model years. My 2010 was built in 2009 (as were most, if not all).

Here's an excerpt from Wiki as to when the 3rd gens hit the showrooms:

"The redesigned 2011 Sienna premiered at the Los Angeles Auto Show in early December 2009. It was designed at Calty studios and engineered at Toyota Technical Center in Ann Arbor, Michigan and Toyota Motor Corporation in Japan.[23] The new Sienna arrived at dealers in February 2010. "

Based on that, I figured that the PID info referred to production dates, and NOT model years. . . . but I've never found any absolute confirmation. If anyone has, please share it.

I would be very surprised if it didn’t work for your 2010 model. 2010 Sienna is still gen2 and there’s no way Toyota would have replaced the ECU and/or TCU for a single mode year.

There’s one sure fire way to find out if it works or not! Even in the slim chance it doesn’t, you will have a nice small wireless OBD code reader.

Thanks gents. I'll give it a try and report back soon.

No luck so far. I think I need to purchase the "enhanced diagnostics" add- on for Toyota .

 

I believe the free version of Car Scanner will let you test the formula, but you may need to get the pay version to add a gauge with a custom formula to the dashboard. It wasn’t much $$.
