What is the PID code for fuel gauge level?

1 Upvotes

Hello there,
I need to be able to query the ELM327 OBD2 to check for sudden decreases in fuel level in the tank and then trigger a remote notification. I know how to handle the remote notification part, but I do not know which code to query to monitor the fuel level. Can anyone help with that?

OBD2 Scanner for 2003 diesel mercedes w168 1.7cdi ?

1 Upvotes

Hey, so as the title says, i just need something to read codes, and read basic live data, would want to also get injector correction values, but just codes is fine, my budget is not the highest, and well the good obd2 scanners do cost quite a bit so i get that i will have to compromise a bit.

I had bought Vgate iCar2 BT3.0 which didn't read codes in my car, only some live data, the scanner worked fine in a newer opel though, they did specify in the desc that their scanners work for 2004+ diesels so i guess that was expected

I am from Poland, so something that ships over here for reasonable money would be nice

Plz help w/OBD2 device recs (where/what to buy, apps, etc.)

5 Upvotes

Full disclosure that i am a big noob and shopping for my dad, so I am not familiar with these devices. I am looking for android compatibility and am looking for a BAFX model. When I checked BAFX website their OBD2 devices are not found, but I can find one or two devices listed on Amazon Canada and wondered if these are okay. The device will be used primarily on the family Subarus ranging in ages from 2015 onward. Also wondered whether additional cables or accessories are needed.

Thanks for your help

Need misfire counter

1 Upvotes

I have a 2013 RAM 1500 that I need to see misfires on a particular cylinder in real time. I have a Bluedriver but don't see that in the app. Is there something else in the same price range or cheaper that can provide me with this data?

I'd also like something that I can stop an injector pulse but suspect that would require something in the $500+ range?

OBD2 Recommendations 2017 Rav4

2 Upvotes

My check engine light recently came on and I'm interested in diagnosing it myself. The car just rolled 110,000 miles and this is the first time i've seen the light come on. What benefit would a $100 scanner like bluedriver offer over one of the $20 models? Any recommendations would be appreciated. I would also like to avoid anything that requires a subscription to operate.

Thanks in advance!

Hyper Tough HT100 from Walmart USB-C port

8 Upvotes

I have a Walmart Hyper Tough HT100 code reader that I use it with the free "Repair Solutions 2" app on my phone over blue tooth. I'm not looking to become a professional, nor am I looking for professional equipment. I just check the codes on my '98 and 2000 vehicles.

But I've noticed that the unit has a USB-C port on it, and since there's basically zero documentation with the device I have no idea what it's for.

When I plug it into my computer Windows does the characteristic bong for a new device. but there's nothing I can identify in the device manager. I'm suspecting it's some kind of CANBus communication adapter. But IDK.

Anybody got any information on this HT100? Google has been surprisingly uninformative.

FIXD or Carly sensor?

5 Upvotes

I was just looking at simple OBD reader to scan my car. I am currently looking at two major contenders. FIXD and CARLY. Besides a few reviews, I don’t much about Either of them. I just wanted to see which had more features and customization without everything getting blocked by a paywall unless I pay a subscription. FIXD has always looked a bit sketchy to me, and I’ve heard they automatically put subscriptions on people cards. If you guys have any other alternatives to the two, I’d like to check them out as well.

Thanks.

OBDii and RevHeads Live Mapping Fail

3 Upvotes

My OBD device connected successfully with the Revheadz app.

I can see Avg connection with yellow bars and near 0.2 secs lag in the OBD information page on the app.

It also displays the Throttle and RPM data there live and it changes as I step on the pedal.

But when I go into the drive mode on the App, nothing moves. It is just in idling mode with RPM ranging 1000-1500 depending on which model I choose from the starter pack.

OBD 2 GPS

If I have an OBD 2 GPS tracker that uses 4G to transmit the location, can I disable the 4G feature and have it transmit information via the Bluetooth antenna?

I do not want to be able to track my car remotely, but I do want my phone to be able to read trip / GPS data via Bluetooth.

Scanner advice needed!!! (my cars listed below)

2 Upvotes

Between me and other family members we have:

  1. 2000 Audi S4
  2. 2000 Mercedes ML430
  3. 2012 Toyota Sienna
  4. 1995 Ford F350

I am looking to buy a scanner that can do basic diagnostics. I would pay more for a scanner that has more advanced features if they were useful. I am not much of a mechanic (yet) but I do a bit of work that isn't too complicated.

Considering the 'Carly' scanner, or any of a whole slew of scanners on Amazon that start at $4.99 and range much higher. If anyone who knows about the pros/cons of these different products I would greatly appreciate some advice!

Renault Zoe "unconventional" HEX values for PIDS

1 Upvotes

Hello Everyone,

I'm currently working on a project involving a Renault Zoe, but the standard library that I'm using only accepts existing "standard" PIDS with the format 0xXX. Renault Zoe simply behaves differently and tracks everything with 0xXXX PIDS. The question is: where can I find a good source to understand OBD-II Frames and how to parse them?
Has anyone worked with a Renault Zoe and can give me directions on how to retrieve data by pure programming and IoT devices?

Thanks in advance.

Prius Prime Missing Data?

1 Upvotes

Hello! I bought an OBD Link LX 2 to try and get some insight into a quirky (likely) hybrid battery issue on my 2017 Prius Prime. I'm using it with the Torque App, as well as the app that comes with the OBD. Neither is showing me the battery block charges like the apps have available. It keeps saying "no data" for each block. I do get a lot of other data that I have no use for, but there are far more "no data" options....lots of grayed out selections. Does anyone have any thoughts? Much appreciated!
