There are only 3 kinds of OBD2 scan tools (some good some bad) "sorry not testing all 1000" but ,,, can talk all day on tools. sure.
If serious on diagnosing engines, (etc) on cars the tool makes the man ! (pays for it self, RIO profits real)
1: dedicated hand tool but is really only a code reader, mostly useless, this. "just a code reader"
2: dedicated tool like this , (real) and some do factory codes too,P1xx p2xx ETC. (VAST CHOICES SOME GOOD SOME NOT)
3: usb OR WIFI DONGLE DEVICE TO PC OR PHONES. BUT THE SOFTWARE FREE SUCKS. horrid in many cases, I use $100 app on laptop above, and nothing works better for less $
There are like 1000 scan tools now, not one new one have I seen , all mine are from Innova or Scantool.net and OBDwiz
I have Innvoa 3100 and 3600 (old) and blue-tooth and wifi scantool.net dongles. (prime grade these are)
I'd never own one that can not PID plot (X/Y) any sensor I want. it has to do plots, for sure O2.
most tools consumer are sold with endless hype and zero facts, (best is RTM first read the manual to see if the thing can plot data or log it , both be super useful) they (scantool.net) even list all PID supported (nice)

I HAVE 3 OF THEIR TOOLS INNOVA HERE, THESE ARE NEW i DO NOT HAVE NEW tools (5years old all)
SEE THE below MATRIX CHART, NOW THAT IS GOOD OF THEM !
see LIVE DATA STREAM FEATURE. also called (tech'like) PID code plotting and or LOGGING PID ( this is raw sensor data etc)
https://www.amazon.com/gp/product/B01MR7...slink=true
the OBD2 scan port 16 pins, one pin is power 12vdc, and the fuse is blown here, the scan tool will FAIL. (my OBD2 pages tell all about that and where the fuse is)
last is our buddy Mr, Scotty. see his OBD2 , plot 02 front.
" you get alot more information with a plot" PID data streaming plots.

the 02 (B1S1) can fail for many reasons besides, just melted wires. there.
1: heater dead. bad sensor.
2: the 02 Cell (oxy cell) is dead, from age or poisoned using some nasty FUEL treatments, (chevron techron is ok, as it is only Benzine CLASS)
3: exhaust cracks make it lie, but is not damage to the sensor, (lucky) fix crack end story.
scotty told my cheap tool blew up my car, (no blew up my ECU/PCM) yes,
those most cheap dongles use a CHINA clone of ELM chip (canada maker stolen !) and has a cheap nasty 7805 voltage regulator in the dongle, see my ELM pages for why.
the answer is SCOTTY DID NOT LIE, (noobs are funny lacking electronics facts) that regulator will blow up in any car made, it sure will.
and then 14.7 volts hits the data ports from ELM to ECU /PCM and blows the input receivers in the ECU, (some cars have PP poor protections here, a FACT)
do not buy $20 tools, ever and then jack it in to your ECU/PCM. 16pin OBD2 port.
ok here i is

do not use china cloned crap in your car. for sure THIS CRAP. (the real and true maker ELM is not bad or evil , just genius) facts!
here is proof of bad, seen here. 7805 never belongs on ANY CAR ON EARTH EVER. (yes I could design a fix here to protect this and all) but why would I fix CRAP.
this is from ebay china, the most cheap made, and never to be used on any car. " no name maker," I needs a real regulator for cars not kids toys, BOOM.

the bad event happens like this, 7805 blows up( in cars) and that puts 14.7VDC on to the other 2 chips and then they blow up, BOOM and in turn blows up, ECU, (via the seriAL TX pins out of the tool to ECU boom kiss off $500 ECU or more.
the reason is the goons in china never read the rules on cars for power surges on cars ever,

check out the NOISE spike cranking, boom kiss off 7805 (25v max input and boom smoke out time.) also bad is A/C clutch electromagnet DC load dump Back EMF spike (or weak battery not acting and great noise filter )car.
