Scangauge question

[nealmccarter]

I've been looking at getting a Scangauge for my 2007 Toyota Sienna to monitor transmission fluid temperatures. Because of conflicting information on the code for this combination, I've hesitated to buy one.

Now that we are scheduled to pick up our trailer, I'm wanting to figure it out. Has anyone has installed such a monitor to a '07 Sienna and have it work properly?

Make sure you can get the codes for the transmission temp. We have a ScanGauge and like the info we can get from it - it has helped improve fuel economy - but are unhappy that it seems impossible to get workable codes for the transmission fluid temp for our Frontier. ScanGauge sent us some codes to try but no luck.

I managed to get the trans temp codes for my 09 Tacoma

Check the scan gauge website for specific vehicle information. You could also call or email them. There are codes available for Toyota.

I would search SiennaChat.com, since I know this question has been answered there... although you may have already done so (it may be one of the conflicting information sources). My Sienna is a 2004, and my OBD gauge is not a ScanGauge, so no - I can't help with experience with 2007 codes.

I can't help. I think my new truck does everything except the dishes.

But, I do know there are several threads in the archives about the Scan Gauge on FiberglassRV. If that helps you. Check out threads about Scan Gauge by Norm.

Our TV is a 2008 Sienna which I installed the Scangauge....the following link should explain the different codes that have to be added for it to read the transmission temp.

Thanks for the info A&B. I went ahead and bought the TransGauge II and used the settings for the 2008 Sienna. I can now report that transmission temperatures for the 2007 Sienna can be read.

For anyone with a 2007 - 2009 Sienna, these are the settings for the transmission temperatures:

TXD = 07E021D9
RXF = 032180000000
RXD = 1810
MTH = 00070064FE70
NAME = TFT (or any 3-letter abbreviation--your choice)

Excellent!
This presumably applies to the 2010 model year as well - the transmission change didn't occur until the 2011 model year.

Probably, I just didn't see a post saying it worked from an owner of a 2010 on the Sienna Forum.

Got my Scangauge II installed and setup last week. Was able to find the following X-Codes for two transmission fluid sensors for the 2011 FJ Cruiser:

Sensor #1
TXD 07E02182
RXF 046105820000
RXD 3808
MTH 00090005FFD8
NAME TF1

Sensor #2
TXD 07E02182
RXF 046105820000
RXD 2808
MTH 00090005FFD8
NAME TF2

Settings are for temperature in Fahrenheit.

Took the FJ and Escape for an overnighter on the weekend into the foothills about 1-1/2 hrs southwest of Edmonton. Transmission fluid temperature readouts worked fine and it appears that I will be able to track temperatures at will.

Update: After towing the 19' and monitoring the transmission temperature, we installed an additional transmission fluid cooler. Seems Toyota's tranny cooler is integrated with the radiator and is limited. The additional cooler made a big difference. Now we can tackle the Montana mountains without worrying.

Dave, where did you mount it? And do you have an additional tranny cooler? I have got to get Dory (2012 FJ) ready as Bailey is in production!! What trailer brake controller do you have? I'm thinking the P3. Thx. Kris

I have installed the Scangauge in what I consider to be a "temporary" location, mounted on the topside of the steering column, just behind the steering wheel. I have used double sided velcro tape for this. It is not an ideal location. Longer term solution will involve installing a more permanent mount, either to the side of the steering wheel or above the rear view mirror. Above the mirror would be best but would require getting a slightly longer cable for the gauge. Here are a couple of pics of other peoples installs that seem to be good locations.

I only have the factory transmission cooler that is installed in the radiator. I will be watching transmission temperatures closely over the summer and will decide at that time whether a secondary transmission cooler is required.

I bought the Tekonsha Prodigy Rf brake controller. Cost about $300 Cdn with free shipping. (http://www.hitchweb.com/product/88/9...-Brake-Systems) This is a wireless controller and is quite simple to install and use, especially for a vehicle like the FJ that is not pre-wired for a brake controller. It does require that power be supplied to your 7-pin connector from the tow vehicle battery. The handheld controller plugs into a 12V outlet inside your vehicle and I have mounted mine to the dash with velcro. Is very easy to unplug and put in a glove box when not towing. So far, the system has worked very well and has been quite reliable.

FWIW...
I have a Scangauge II I bought maybe 4 years ago to watch the tranny temp on a truck I bought from the auctions and didn't trust when towing. I found that the temp on the SG is very accurate as opposed to the needle gauge on the dash. I'd see a 50 degree swing on the SG and start to worry while the dial didn't even budge. After 1 season of using the SG and having my anxiety level go up proportionally to the amount of movement shown on the SG I stopped using it, too much info.
You need to figure out what an acceptable temp range is for your TV, mine would go as high as 240 climbing long hills down to a more normal 170 or 180, depending on outside temp. All the while the needle on the dash happily sat at the same spot. Takes a while to get used to seeing the temp quickly climb and then ever so slowly drop again. I believe you don't want to see above 240, but that may have just been the GMC.
I went to the extent of adding a 2nd tranny cooler just to the side of the radiator, helped the recovery time some.
I used Velcro on the steering column like Dave, after a while I guess the heat got to it and the glue gave way and the gauge would slide off to the side. I didn't try the super duper clear 3M Velcro like the EZpass uses to stick to the windshield, I wanted to be able to remove it someday, but that may be an option.
