For checking codes, any off the shelf obd2 reader will do.
If you want to have fun, ELM327 based OBD2 readers are all the rage right now. You can pick up a bluetooth version for ~$40 on amazon or ebay. Several iOS and android apps (like Torque) exist that can read a signal from these adapters and do full on data-logging. This will let you read/clear ...

If you are simply buying it to try to fix your car, and not as a tool to have, car part stores sometimes read the codes for you. The readers will usually have a description, but if not OBD-II became a government standard in 1996. The codes are basically the same accross the board, and any additional codes are manufacturer specific. To translate them, you can ...

As Tim suggests, clearing the code doesn't solve the problem if it's not a random positive.
The engine temperature gauge is fine
Based on the information that you've provided so far (and using Tim's link as a reference), it seems likely that you have either a bad engine coolant temperature sensor. The implication from your PS is that the car is, in ...

I can't speak to the Torque app, but in my experience the US Gov ratings are typically quite a bit lower than what you can expect to get in actual normal driving (Gov ratings seem to be based around someone that does 15mph+ over the speed limit all the time, launches from every stop light, does full-throttle passing, and doesn't see red lights until they ...

Look at the ALDL connector if you have this on it's OBD II
If you have something differant like the one below, it' not OBD II

Be cautious, OBD-II is not as standardized as most people think... Ford & GM both went their own ways with early OBD-II cars and industry standard "ISO only" readers won't work on them. You need tri-mode readers that also support VPW (? going from memory, I believe that's Ford's OBD-II interface) and whatever GM used. Side note, the Toyota Supra ...

Off the top of my head, the easiest way to get there would be using some sort of hobbyist microcontroller board, such as an Arduino. You'll need to add encoders since most of the data you'll be receiving will be analog.
Since the CPU for your board will include timing by default, you can calculate time-based measurements (RPM, MPH, etc) from that.

Well, It's not necessarily dealing with the ELM327, but this looks like a FANTASTIC solution.

No longer getting developed.
Apple is currently not allowing developers to use Bluetooth for this purpose. The only real connection is via Wifi.
My initial "assumption" was that if you're connected via Wifi, then your 3G data is disabled and ...

This can be reproduced by turning the ignition on and off 3 times (somewhat quickly). ON, OFF, ON, OFF, ON. On the last ON switch, the speedometer should cycle through any error codes.
I also found a site that documents this. Different vehicles seem to have different variables: http://www.allpar.com/fix/codes.html
According to the site, this should be ...

Apparently, code 1684 indicates a loss of power to the powertrain control module.
One of the risks seems to be corrosion on the battery terminals or cables. As the easiest way to clear this code is to disconnect the battery (resetting the code and the check engine light at the same time), that would be a good time to check the battery posts for ...

To get smogged in California, you generally need to go to an "inspection-only" shop, that is, one that will only test your car but not fix it if it fails. (If it fails, you go to a regular mechanic and fix it, then come back for a free retest.) I believe the system was put in place to counter fraud; I don't really know how well that's working out.
In any ...

Interestingly, you can read the code without a scanner. The airbag light or ABS light (and even the check engine light) will all blink the codes when the OBD-II connector is properly bridged. For example if it blinks 5 time slow and 1 time fast you have a 51 code. All you'll need is a paper clip.
This video below will demonstrate how to do it. I just did ...

Readers for air bags, ABS, etc can be quite expensive. You can try searching online for PC apps and cables that might do it. I'm hoping somebody has come up with one by now. Last time I was looking for an ABS code reader for an OBD-II car it was ugly. The device was called a "MUTT-II" and cost $5,000. Even worse, it required a vehicle specific ROM pak, ...

If you're not sure why you would need one then no, it would not be a good purchase. You would be much better off telling us what's happening with your car: we might be able to be of assistance given some information on specific symptoms.
The on-board diagnostic port will look something like this:
It serves as an interface port that the engine computer ...

I'm leaning towards a bad thermostat. They gunk up and fail over time (usually on the "too cold" side). My experience with factory coolant temp gauges is that they're pretty much useless. My experiences show that the coolant temp can be a good 20 degrees (F) off of normal and the factory gauge will still sit in almost exactly the same spot as if the ...

Since the vehicle is a 96, the mechanic might have meant that you need 2 or 2 more OBDII monitor readiness checks. Some emissions systems are checked continuously by the powertrain controller, while others are only checked periodically when certain driving conditions are met (FAQ).
Has your battery been disconnected? That could have reset the monitoring ...

If you're looking for the OBD2 pin-out on the vehicles end (female) then it the interface type and pin population will vary from vehicle make to vehicle make. In order to tell you'll have to start by locating the OBD-II Connector.
I'm going to assume since you're asking about this you know where to find this connector
The connector has metallic contacts ...

I was looking for the similar thing and stumbled on a page which describes the protocol for the 650gs. I haven't managed to try it out yet but it seems promising. http://www.f650gs.crossroadz.com.au/Diagnostics.html

It was true a few years back but they charged a fee and then when it was returned, they credit it. That's a hassle in itself. This tool could work for future cars/truck as well.
As long as you get one you can update. You might want to consider one with a erase code feature. So the codes don't remain in the obd scanner. Or pay someone to get it out of ...

No it is not worth the cost.
If you live in the states almost all major auto parts chains (Advance Auto, Autozone, etc) will do a check or even loan you the tool for free. Unless you're checking codes daily, it's just not cost prohibitive.
The error codes produced by OBD2 are rather generic. They can be helpful in pointing you in the correct direction but ...

Be sure to consider one that links to your smart phone. There are several models that link via Bluetooth, which work on Android phones and PC. Googling "obd2 bluetooth" will find what you need. They don't work on iPhone as the Bluetooth profiles on iPhone are limited, but wifi models are available.
Software on your phone (like Torque) or PC will let you to ...

Clearing out the error shouldn't clear it out for good. If the problem persists you should see the error code come back again.
You may have already checked it out, but here is some info on your error code: OBD-II-Code-P0128

Is it the one pictured at the Elm327 Bluetooth website?
If so then the passcode should be 1234 although technically they say that the passcode is
" 1234 "
It's been a while since I paired a bluetooth device but I think you only get 4 digits to work with, not 6, and I think only numerics are allowed so no spaces either, which brings us back to ...

Judging by this...
CAN bus is one of five protocols used in the OBD-II vehicle
diagnostics standard. The OBD-II standard has been mandatory for all
cars and light trucks sold in the United States since 1996, and the
EOBD standard has been mandatory for all petrol vehicles sold in the
European Union since 2001 and all diesel vehicles since 2004.

Unlikely, but I can't say for certain. AFAIK, Mitsubishi first started putting OBD-II diagnostics ports into the 1995 model year cars (in preparation for the 1996 OBD-II requirement).
Most likely is OBD-I, which would require a proprietary plug (or jumpering of a couple pins) to read/force a code display.

It's been a while, but from what I remember there are some strange rules that have to be followed in order to import a car into California.
Depending on when it was purchase and/or initially licenced, you may be OK - any car less that 4 years old should be OK to register in CA. If it's older than that, you'll need to get a smog check by a state-licenced ...

I know that you are looking for a Android solution so I am going to send you to an iPhone site. Actually, they have a nice list of hardware there which is open enough that they can support it as a third party. You can find Andriod software for any of these devices. You may also have to click on the hardware tab since the deep link does not seem to work.

Not the only game in town, but it is probably the most popular. Probably 90% of the standalone EMS ...
