Adding PID To Scangauge II

Hi,

I've been reading and watching and searching but must be missing something;

How do you add PID's for transmission temp for a 2013 Tacoma?

I have found pages that have the codes but can find nothing about if they are there and I have to discover them or manually add them. And if adding exactly how...

Really just want the TFT for towing a trailer......

Thanks,

A

 

Subd... I was trying to figure this out the other day and couldn't figure out how to enter them either.

 

You have to manually enter the codes for your particular vehicle. It tells how on the Scangauge website. If you can't figure it out, get a teenage kid to do it for you. They may not know which direction to turn a bolt, but they can sure wiz through techy stuff.

 

What OBD2 reader and app are you using?

 

Ummmm .......Scangauge II......

It's ok! I ask questions like this all the time instead of reading the title

 

Yes, I saw that after I made the post. When I get back home and in front of my desktop I'll send you the PID that I used for my transmission fluid temperature.

 

You have to manually add the TFT codes. The scangaugeII manual shows how starting on page 37.

That's quite a gadget you have there. Once you get it placed and running post some pics have you have it setup. Here's the PID I used for my truck and it seems to be pretty accurate. Hope it works for you too.

For sensor 1 (Pan Temp):

OBD2 Mode and PID:
21D9

Long Name:
Transmission Fluid Temperature 1
Short Name:
TFT 1

Minimum Value:
0.0

Maximum value:
220.0

Scale factor:
x1

Unit Type:
°F
Equation:
((((E*256)+F) * (7/100) * 400)/10)

OBD Header to use:
left blank

For sensor 2 (Converter outlet temp):

OBD2 Mode and PID:
21D9

Long Name:
Transmission Fluid Temperature 2

Short Name:
TFT 2

Minimum Value:
0.0

Maximum value:
220.0

Scale factor:
x1

Unit Type:
°F

Equation:
((((G*256)+H) * (7/100) * 400)/10)

OBD Header to use:

Which sensor is better to use? The pan temp or converter outlet temp? I have the trans temp showing on my scan gauge for my 09 Tacoma but I don’t remember which code I used. On mountain grades the trans temp gets up to 208 to 210 degrees just with the Tacoma.

 

I have a gauge for each sensor set up on my Torque app. As I recall, the converter runs a little hotter. I haven't been really driven my truck much since last May when I drove back to Texas from AZ, which was not on IH10. So my memory is a little foggy on that. From what I understand, the coolant temp and trans fluid temp will be pretty close when the vehicle is under strain, as in driving on mountain grades.

 

I have noticed my trans temp gets to around 208/210 while the engine temp will be in the mid 190’s while climbing a high elevation mountain pass with multiple grades (this would be Monitor Pass highway 89 in California).

 

IMO- that's quite a difference. Do you have a trans cooler, or just relying on your radiator to cool the trans fluid? There could be several reasons why your transmisison is running 20° warmer.

 

My Tacoma has the tow package so whatever trans cooler it comes with is what it has.

 

On my 2000 4R my OBD iPhone app would have similar 220° range readings.

Remember putting in OD will drastically raise trans temp so gear selection a factor.

I don;'t think engine and trans temps are always the same ...
