Which Code Reader/Scanner Diagnostic tool should I buy and why

My tacoma has check engine light on. I am thinking about buying obd code reader/diagnostics tool. Can anyone suggest me one please.

 

Get a scangauge or an ultra gauge. Both a code reader, and multi function gauge unit for the truck and will help track gas mileage, etc as well!

 

Blue tooth OBD II reader and torque app. 20$ on Amazon

 

I love my SGII

but if all you need is codes read, Autozone does em' for free.

 

You could try search feature.

 

Scanguage II

Code reader/fixer(some)

and then some.

 

how about this:
Equus 3100 Innova CanOBD2 Diagnostic Tool

Has anyone used this? I see one for $100 at walmart

 

Ultra gauge is cheaper and does more.

 

x2... you'll only need the Torque app if you have a Droid phone and want to use it on that, which is nice, otherwise it comes with software you can run on a laptop. Search on Amazon for ELM 327

 

I love TW.

I was looking around for a OBD2 software tool. Took me 3 seconds to find the info I needed!

Looks like this is the one to get though:

Search Amazon for: soliport ELM 327

Apparently it has more features than just the ELM 327 and costs about $1 more.

 

Has any one used this? I see this on sale at Autozone for $49.99 and thinking about buying one. Is this any good?

 

Got the 327 a few weeks ago..lovin it

 

I have an older actron, similar to this newer model.

Its a great reader and can be bought on sale fairly often. I still carry it even though I now have a scangauge in case I need to pull a code on someone else's vehicle or want more detail than the scangauge offers.

I got as a half joke christmas present from my family because I always had the check engine light on in my old truck even though it was a faulty O2 sensor reading that never went away even with both changed.
