Write-Up: Torque APP OBD2 Reader

I assume since it gives a vacuum reading, its a negative vacuum that is detected and is interpreted as boost. as if left on the metric unit inches of mercury is the unit used (a positive vacuum read). It has a sensor on a vacuum is all I can come up with. I don't understand why newer models don't monitor that but it seems to be the consensus

 

But, again, w/o a MAP sensor how is this possible? What sensor is reading vacuum if not a MAP?

 

The vacuum sensor. I dunno man all I no I plug it in and it works.

 

Hello all, Im glad to see that a lot of progress was made determining the PID equation for tarnny temps in 2006-2013 Tacomas. I see there are some people that say they have tranny temp for 1st gen tacomas, but Im having difficulty getting a reading on my 2000 tacoma prerunner (V6).

Can someone that is getting good transmission temp readings on a 1st Gen Auto please post the PID equation/parameters that they are using?

Thanks a bunch!

-Jay

 

Was the pid for 2nd gen posted in this thread?

 

This is for the 05-09

Did you use the 21D9 PID equation below?

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 (there is a degree symbol in Torque)
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 (there is a degree symbol in Torque)
Equation:
((((G*256)+H) * (7/100) – 400)/10)
OBD Header to use:
left blank

 

And this is for 10+ trucks

Ok I think i figured it out for the 2010+ Tacoma

For sensor 1 (Pan Temp):

OBD2 Mode and PID:
2182

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)

OBD Header to use:
left blank

For sensor 2 (Converter outlet temp):

OBD2 Mode and PID:
2182

Long Name:
Transmission Fluid Temperature 2

Short Name:
Trans 2

Minimum Value:
0.0

Maximum value:
300.0

Scale factor:
x1

Unit Type:
°F

Equation:
((((C*256)+D) * (7/100) – 400)/10)

OBD Header to use:
left blank



I'm going to set the truck into the Diagnostic Mode to check and see if the numbers match up. If the PID and equation are correct, the A/T Temp light should light up at 115°F and start flashing at 130°F.

 

I stil need to work on my setup AGAIN>

 

How do I add this and make it work on my junk?

What are your settings for DTE? I can't figure it out and its just way off

 

What's wrong with it?

Que?

 

I keep doing custom ROMS. Forget to back up my data for Torque, and when I wipe my device I need to setup the app all over again.

 

Thanks for the info..

What I'm trying to say is the distance to empty is off and not even close. And I'm having a hard time trying to get it right. I Havnt messed with it in a while trying to figure it out.

 

I have no idea what that is

No problem.
Ahh, OK.
I have no idea, i just got my know how from the AZ geek talk thread.

 

Mine lasted a month...get what you pay for

 

I got that nice adaptrr. 150.

Also. Torque is up to 1.8.1 http://forum.mobilism.org/viewtopic.php?t=637962

 

Anyone have the 1st Gen tranny temp parameters?

 

I didn't go through the whole thread, but I looked some and didn't find any, and I tried the codes for the 2nd gen and they don't work.

 

when I try inputting the codes it would not take the equation values and keeps telling me this message; equation: check parentheses. Anybody know what is going on here?


Do these codes work with the free version copy of Torque?

I have a 2005 Tacoma 4.0, 6cyl

 

I have a '99 4Runner (3rd generation) which is very similar to 1st Gen Tacomas... I have the iPhone app "Engine Link" which also allows for custom PIDs. Try this one, it worked for me:

OBD2 Mode and PID: 01B4
Long Name: Transmission Fluid Temperature
Short Name: TFT
Minimum Value: 0.0
Maximum value: 300.0
Scale factor: x1
Unit Type: °F
Equation: A*(9/5)-38
OBD Header to use: 0 (I put in zero for my iPhone's "Engine Link" app. You might need to leave it blank for Torque)

 

Thanks, Ill give it a try and post if it works (may be a week or so before I have time to get around to this)
