I need help finding the correct torque PID for reading the transmission temperature for my 2015 Toyota Highlander XLE with the V6 with the U660e transmission. I have used the following PIDs and none of them work.

OBD2 Mode and PID:
21d9
Long Name:
Transmission Fluid Temperature 1 (or what you like)
Short Name:
Trans 1
Minimum Value:
0.0
Maximum value:
300.0
Scale factor:
x1
Unit Type:
°F (or alternatively C is you use the second equation below)

Equation:
((((E*256)+F)*(7/100)–400)/10)

OBD Header to use:
left blank

For 2010+ cars (do not own one, so I have not tested this)

OBD2 Mode and PID:
2182 (NOTE DIFFERENT PID for newer Toyotas)
Long Name:
Transmission Fluid Temperature 1
Short Name:
Trans 1
Minimum Value:
0.0
Maximum value:
300.0
Scale factor:
x1
Unit Type:
°F
Equation:
((((A*256)+B)*(7/100)–400)/10)

try to put in these 2 PIDs Header 7E1
what is the response to these PIDs in the PID Test mode?

I am new to programming Torque Pro App. When you say “try to put in these 2 PIDs Header 7E1”. While in OBD2 PID Editor, Do i just use “7E1” or “Header 7E1” in the OBD2 Mode and PID line.

Thanks cintakc I added 7E1 to the line you instructed on PID 2182. It appears to be functioning as it was giving me a reading independent of the engine coolant and did not fluctuate as I was driving. Reading of 145 degrees after driving for awhile and the after an hour of it being parked it was down to 133 degrees.

Test results:

Response 7E90461826220

Variable:
A=98(HEX=62, Binary=011000010)
B=32(HEX=20, Binary=0100000)

PID 21d9 was giving me minus readings.

Thanks for the information and help. I was just about to give up and buy a Scangauge.
