The transmission temp doesn’t work on torque with my 2007 toyota 4runner. I followed a guide that i found on here for translating xgauge code to PID codes, but now it displays the temp as being over 2000 C.

here is the original xgauge code:
Gauge: Transmission Temperature TXD:07E021D9 RXF:032180000000 RXD:2810 MTH:00070064FE70 Name:TFT Notes:Degrees F

This is my translation:
PID:
21D9
Long Name:
Transmission Temperature
Short Name:
TFT
Min value:
0
Max Value:
230
scale factor:
1
unit type:
F
Equation:
((A*256)+B)*10*(7/100)-398

I got confused constructing the equation and i’m pretty sure something is off (i hope the tranny isn’t 2000 C)

any help would be appreciated!! thanks!!

that is similar but is using codes for a newer vehicle. i will try them though.

also, it’s now a puzzle and i’m curious where i went wrong. it’s been too many years since my undergrad programming class to remember what to do from here.

so the variables were different, but i think that i’m getting a value that is realistic (124 F on a very short trip around the block after the car was sitting for several hours).

i left out the OBD header because it wouldn’t work with it inserted. in this case, are the variables different sensors that are being pinged…..i’m confused about how it’s working (not that i need to know, just curious)

thanks for the link. it was very helpful

Sure. Like i posted above, i think that this is correct value, but i haven’t checked it against anything else to make sure.
