'Check Engine Light' Trouble Code Reader - Everyone Go Buy One of These
|
I've been dealing with a car that keeps having the CEL light on and I need to get it smogged. Instead of taking it to some mechanic dork who'll charge $$ to just read the codes, I bought this:
http://www.amazon.com/gp/product/B001LHVOVK/
It ended up being a trouble code that (appears) to only take about $10 to fix it.
This saved me a good deal of money. Everyone should own one of these things. Stupid engine lights shouldn't be so "mysterious".

Yeah - but you might still have to wait, it's a hassle, and there might be a sales pitch.
Reading the sucker by yourself in your own driveway, with a device that cost a mere 21 bucks plus shipping, is awesome.

Indeed.
I've never bought one but a friend of mine has one and lets be barrow it when ever. Great thing to have around.

I have one and it not only told me I had a oxygen sensor going bad but which one it was, they also clear the check engine light so people riding with you won't think you are an idiot.

thats a waste of money.
those things only read obd2 generic codes and not factory specific codes.
they are the equivelant of buying a thermometer and thinking youre a doctor.
what was your trouble code?
ill tell you what it really means and how to go about fixing it

yes
ive used several brands of those "OBDII" code readers.
ive also used the $8000 diagnostic computers.
you cant get into manfucturer specific data without a key card to set the connector pins correctly.
i did this type of work with scan tools and in depth computer diagnostics in autoshops for 15 years. i watched the industry evolve from simple mechanical carbeurators to digital computer controlled fuel injection with drive by wire.
if you ever want to know anything about automotive computer systems, feel free to ask. i dont mind giving out advice.
i can also tell you that there is NO fix that will cost you under 10 bucks if it turns on a check engine light.
unless you put gas in the car while it was running and triggered an evap code, p0442(?), then youre not getting a computer repair for under 50 bucks.

good luck with that.
was it a misfire code?

or actual maf sensor code?
is it a VW?

Why would anyone ask your advice when you obviously don't realize pin outs can be preprogrammed and auto set depending on the manufacturing info that is static and default readable by any OBDC2 device?
Obviously you don't know as much about all aspect of automotive repair as you thought...

Thanks - I already did it. It is a P0171/P0174 with no noticeable symptoms - the car drives and idles just fine. The common diagnosis is that the MAS is either dirty or faulty. I'm shooting for dirty first. I just have to drive it a few days and see what the monitors say.
Edit: and technically the fix was about $6.50 for the MAS cleaner. I also bought an air filter which pushed the price up.

thats the system lean codes.
take a can of carb cleaner (or something flamable) and spray it around the top of yer engine.
if the cleaning the maf sensor doesnt do it.
and reese
reprogramming the pinouts would be awesome if the manufacturers shared their pinout info.
im pretty sure thats proprietary. hence the use of keys.
as well as some of the keys being solid state themselves to unlock or decode the manfacturers programs.
theres more to it that just pin locations.
yer right, though. i dont know as much about the keys as i do about using the tool and trouble shooting problems.
i never gave two shits about the keys as long as i had them and could get done what i needed to get done.
i can also guarantee that a 20 dollar code scanner does not give factory specific codes.
i own about 4 of those things. they all say they give manfacturer specific and none of them do.
they get away with it because the ignorant public who buy those things dont know the diference between factory specific and generic obd2

Sounds like a plan.
I also have read it could be a leak somewhere.
SomeOtherForum posted:
I have a 2000 Ford Taurus that had the codes P0171 & P0174, after reading these posts I checked the vacumm lines and found that the elbow on the PCV valve was split. I replaced it and the valve (total cost $3.98) and it is running fine.
If either of the mentioned plans don't fix it, I'll get to inspecting the vacuum lines.
I have until Feb 20th to get the smog crap in order.

so i guess there is one possible fix thats under 10 bucks
i stand corrected. lol

The CEL light was on earlier, and it needed new coil packs. The guy wanted $1100 to do it.
My dad and I ended up doing it ourselves. Took about an hour and cost $200 in parts (including spark plugs).

Me and my work buddy fixed my thermostat(mostly him) and we worked on it for three hours total. If we were working for the man we would have billed lots of money for that time. BUT I have zero trust in any mechanic. not that there aren't great and honest ones out there, but I think they are a rarity. If I found one, I would gladly pay to have them fix my ride every time.

If you want something that will read codes as well as let you access your computer gauges, check this out.
http://www.ultra-gauge.com/ultragauge/index.htm
Pretty much identical to the ScanGauge except its $70 instead of $150.
Lot of handy gauges that you can configure.

That's pretty cool.
There's also one that is a bluetooth enabled connection to your computer. You can then access it through an app on any Android device. I'm not sure if it shows gauges - but just that alone is kind of neat.

why would you need to see the gauges?
arent they already on your dash?
unless youre going to drop $8k for the snapon or OTC scan tools
then just get the $20 one from amazon.
all of you wouldnt know what to do with a real scan tool anyway

Most cars just have dummy lights, it is nice to have actual numbers.
Engine Coolant Temperature
Fuel Pressure
Air Intake Temperature
Oxygen sensor voltage (that is actually useful on my car)
Battery voltage
Throttle position (handy to stay in the 'sweet spot' when trying to maximize MPG)
MPG data both instantaneous and long term(many modern cars now have, but that has become common only recently)
Dozens of others as well.
Having feedback on instantaneous MPG is a great tool to save money. I'd argue that that feature alone would pay for the gauge in a short period of time for most drivers due to fuel savings from adjusting how they drive.

F a vacuum leak. I will gladly pay someone to look for that stuff. 
I would love to get more familiar with my car though. At the present I usually know what is wrong with it before I bring it in to my mechanic, I just don't necessarily have the time, space, tools, or courage to try and fix it on my own.

why would you need to see the gauges?
arent they already on your dash?
Most cars just have dummy lights, it is nice to have actual numbers.
Engine Coolant Temperature
Fuel Pressure
Air Intake Temperature
Oxygen sensor voltage (that is actually useful on my car)
Battery voltage
Throttle position (handy to stay in the 'sweet spot' when trying to maximize MPG)
MPG data both instantaneous and long term(many modern cars now have, but that has become common only recently)
Dozens of others as well.
Having feedback on instantaneous MPG is a great tool to save money. I'd argue that that feature alone would pay for the gauge in a short period of time for most drivers due to fuel savings from adjusting how they drive.
most cars give out that info.
except from O2 sensor. which o2 sensor does it give you? all of them? do you really even know what youre looking at with that info or is it just a fancy gauge you show off to yer buddies to try and look smart and stuff?
also, tps info is only what your gas pedal is doing. with drive by wire you dont control the throttle anymore, the computer does. as a result TPS /= actual throttle angle anymore.
just about all cars now adays have driver informatin centers that give you read outs of everything from coolant temp to tire pressure, including MPG current, long term, estimated, etc...
