check engine light for several codes

found you a couple of videos about enginelink, might be helpful to you, both seem to be using the wifi reader as well

 

thanks for that, do you think most features would work on an old truck, or does it depend on the vehicle, or do all obd II vehicles have a standard of things

 

So far it has been my experience that as long as your vehicle has the obd2 port that the reader will work in some capacity, newer vehicles will yield better results then older ones, typically just because the computer is better able to diagnose things, but all of them should be able to do things like report what the fault code is, clear the code, read basic engine stats and the like.

or at least that is what my experience with them so far has indicated, someone who has used one of the readers in a professional setting might have more info, all i can say is, i have tested it on 5 different makes and model of vehicles, and all of them worked just fine, i was able to tell what the problem was and fix it every time.

 

My only experience is with torque.. But its great. Like i mentioned earlier, i diagnosed my buddys a4 cel to be a coolant temp sensor. he took it to the shop, and they confirmed my diagnosis. Any sensor your truck has should be read by the reader. Boost has nothing to do with our trucks unless your running a turbo, or supercharger (god i want one of those). You should be able to read: coolant temp, intake temp, engine temp, tranny temp, short term and long term fuel trim (which helps out a lot if you know/learn how to read/diagnose with that) air/fuel ratio, o2 voltage, read cel codes and web search what they mean, gas mileage, info for smog like egr and the like. 1/4, 1/2 mile times. 0-60, horsepower (read as a percentage). I believe a tilt gauge for wheeling, definitely an accelerameter, engine rpm. Put it this way, $30 WELL SPENT. Totally customizable. You'll be charging friends to diagnose there cars!! Your wife or gf will think your a greek god once you show her all the info!

 

i mean i do have the supercharger so the boost would matter, (may have thought i was little dumb there, should have mentioned that when i originally brought that up) and are these all things shown on torque pro? or just in general my truck will display all of these things if i get the wifi reader and the app i mentioned for $6, and i was wondering how big this is, the obd port is quite close to your foot on the gas pedal, would it be in the way at all leaving in all the time

 

As far as the torque app in relation to your truck, everything i listed is gonna show up for your truck. Whatever sensor your truck has, torque "Should" be ableto read it. The obd2 i bought is roughly the size of a pack of cigarettes. Yes its right above your go fast foot, but unless your bigfoot, tou should be fine.just dont leave it plugged in for several days. Ask me how i know!

 

dead battery? but OK ill look into it all, thanks for the help, and im around 50 miles into driving after light turned off ( i know, i don't drive a lot but i was gone for the weekend) and it still hasn't returned and my mpg seems to be much better based on the rate my gauge is going down, so hopefully i wont need it soon but i still do want to order one just to have it for future needs

 

the check engine light came back on, and as you guys said to do check it as soon as possible to see original first code, the code was P0330 which is Knock sensor circuit 2 fault, do any of you guys have experience with changing the sensor? how difficult is it?

 

For one. You need to be able to clear the codes. For two. You need to start back at square one. If you started out with one code. Then you blindly started changing things with out correct info. You probably generated the other codes. It would probably be a good idea to put all the sensors back where they originally came from and start over with your diagnosis. From my experience the only oxygen sensors Tacomas like are the expensive OEM ones that come from the dealer. Or a good OEM Used one.

 

all sensors are back where they should be, except the 2nd o2 sensor, it is a Bosch, secondly the light went back off, so we will see how it goes, if it comes back on and stays spotty like this, i probably have a bad knock sensor harness? maybe?

 

Just wait and see what happens.
