obd2 post Transmission Temperature Gauge

Transmission Temperature Gauge

We have had a few customers ask us how to use our OBD-AUS tool to bring up a transmission temperature* gauge on their phones. This has mainly been for customers who have towing caravans. Even though they have an over-temp sensor and their dash light turns on, by the time the alarm, shows the damage may already be done.

An Example

We will do this example for a Ford Ranger, but the process is the same for any vehicle. The only difference will be the PID you need to bring the data up on your phone*.

1st Step:

Buy one of our OBD-AUS units here for $39*. This will allow you to connect your phone to your vehicle easily. All you need to do is find the OBD2 port which will be within 50cm of the steering wheel and you can access it using no tools. It looks like a rectangle plug with 16 pins and slope sides.

2nd Step:

Download the App onto your phone (for this example we will use OBD Fusion). This is a paid app, and will cost you $15. For the extra PIDs*, it will cost you another $13*. You are still looking at under $50 to have all this data at your fingertips and save you a costly replacement or trip to the mechanic. Note that this app is for example purposes only and you may need to use a different app for different vehicles.

3rd Step:

Turn on your Bluetooth or and search for the device called OBD AUS. Pair with this device; the password is 1234. You are now connected.

4th Step:

Open up the OBD Fusion App on your phone and you will see that we connect you to your car and you can see all the standard data. However, you will not have the extra custom data like the transmission temperatures*. For this, you need to watch the below video.

You have watched the video and added the extra sensors for your car and now you build your custom dashboard with all the information you want to view.

All done! You know have a live feed to your Transmission Temperature and you can even setup alerts if the temperature goes up so that it beeps and warns you.

And for those of you with a Ford Ranger, here are the PIDS below for the Transmission that should work* if your vehicle model is the year 2012 onwards. You will need to enter these into the custom PID part of the app you are using.

PID: 221e1c
Long Name: TFT – Or whatever you want
Short Name: TFT – Or whatever you want
Min Value: 0.0
Max Value: 200.0
Scale: x1
Unit type: ºF – Important
Equation: ((A*256)+B)/8
Header: 7E1


That will show in Fahrenheit. Now the really important part is in Settings/Units make sure Use Celsius instead of Fahrenheit.

*IMPORTANT NOTICE:

Some live data parameters (such as transmission temperature, EGT, oil pressure etc.) may require you to source out or purchase PID codes and program the app to enable such parameter/s to be read. Due to PIDs being very variable, OBD2 Australia does not provide any more PIDs. Most PID codes are taken from different sources online and MAY or MAY NOT work with your vehicle (this also applies to extra PIDs purchased in app). Some readings may be incorrect as well (such as fuel consumption, oil temperature, boost etc). This is because most apps use a generic PID which may not be compatible with your vehicle, to interpret these data. PIDs for certain parameters are subjective to vehicle model year and ECU type, so there are chances that PIDs found online may not work. This is NOT indicative of a ‘faulty scanner’ and any reason for return due to PIDs not working will be subject to our Returns Policy and Terms and Conditions. PID compatibility and non-default parameters are beyond the control of OBD2 Australia and are not our responsibility to make it work or enable compatibility. If you have questions about PID compatibility, please contact the developer of the app (if the PID was bought in app) or the website/site admin you sourced the PID from.
