Hi, I’ve been using the Torque app for a number of years now and I love it. I recently installed an Android head unit in my car so I no longer need my phone mounted on the windscreen

I duplicated my usual gauges all of which worked great in my Galaxy S8, but the Voltage (AD) gauge is reporting no data, yet still works with my phone connected

When going through the add gauge dialogue, the Voltage (OBD Adapter) is green, but not light green like some of the other available data sources

Any thoughts?

Cheers Martyn

I believe the supported sensors under
adapter status icon refers to the OBD
01xx pids from your vehicle.

The voltage from your adapter would
likely use an elm command to read
(ATRV). Are you using the same adapter
with the head unit?

so try another app like obdfusion.
I cant get why this app here is so often used.

Is there a PID for your car somewhere for control module voltage? Could you use that instead.

Torque’s way better than OBD Fusion.

How would I find this PID? Actually, would someone mind telling me what PID means!?

I work in IT so I’m no stranger to working with complex software, and I’m only now starting to realise how much there is to this app!

Look under Adapter Status icon information
for version. 1.8.205 is the current release.

You can add a pushbutton display from the
realtime dashboard for sending commands
and testing the responses.

When you send ATRV, it is recognized by your
adapter as an ELM327 command. Only OBD
commands are packaged by the adapter for the
protocol in use and sent along to the proper
module on the vehicle network.

AMEN Brother! Then you can go download Track Recorder and overlay Torque Pro gauges on your video camera view! And Themes …

This sounds interesting!! Will be looking into that!

Wikipedia.org/wiki/OBD-II PIDs shows Hex 42 to be Control module voltate (formula 256A+B/1000). Lot of good info there to help you get started getting deeper into Torque Pro. Beyond that you need to ‘dig’ for proprietary PIDs for your specific vehicle. They’re harder to find. PID = “Parameter ID”. If you are an IT guy – you can best relate to PIDs as PORT Addresses on your computer. Torque is not reading the sensors. The ECU reads them, filters it through its software formulas, or calculates stuff for which there is not even a sensor and posts the results on a PORT (or PID).

This is really helpful, thank you for the comparison to network ports, that’s gone right up my flagpole, I’m saluting that!

REf: what Capp777 said. Beware if version if Torque was ‘pre-loaded’ on your device or came with a Disk.

Thank you guys for the advice and direction, I’m away for a few days but will be having a good rummage when I get back! Really encouraging to find such a knowledgeable and supportive community behind the app

Your Elm327 adapter uses AT commands
for its commands. ATRV is the elm command
for read voltage as seen by the adapter.

There is also an ATCV command for calibrating
its voltage if a more accurate reading is
known (such as a multimeter).

There are pdfs on the web which describe the
various commands for the Elm327.

Torque should already have the 0142 voltage
mentioned in Wiki.

I just downloaded the latest APK and installed it, which has rectified the voltage gauge issue! So thanks for the hint regarding versions, I thought I installed it on the head unit, but it must have been bundled

Track Recorder uses the device’s camera so
if there is no camera – no image… but you may
be able to get the map overlay with gauges if it
wasn’t crashing.

Also suggest Torquescan plugin for helping
with pids and addresses. The addresses are needed
if you want to customize your themes.

Glad its working now!
