REading 2006 Sonata check engine light code
 

Hyundaitech,

My Sonata threw a code tonight. Is a code reader the only way to access
the code? Is there a secret handshake method such as what GM and
Chrysler have had for years?

For those who don't know, on both of these brands you can read many
codes yourself. On the GM, you short two pins on the code reader
connector and the code will flash on the check engine light. Chrysler
is even smarter. There you, if memory serves, turn the ignition key
from off to on to off to on to off again in less than something like 3
seconds and the code will flash on the MIL.

Does Hyundai have a secret handshake method?

My Dodge would show the code on the digital odometer.

What year is it? My 1996 did not do this, but I haven't tried by newest
Chrysler (a 2003). Maybe it does that also which would be the cat's
pajamas.

It is things like this that has always caused me to hold Chrysler
engineering in pretty high regard. Unfortunately, their manufacturing
has always been mediocre at best.

Unfortunately, no. Such is the case with nearly every OBD-II
product. You'll need an OBD-II code reader. If you're planning on
purchase, choose one that's CAN compatible so you'll get the most
future use out of it.

I think my Chryslers are/were OBD II and they allow reading without the
scan tool. I think my 84 Chevy is called a "partial" OBD II
implementation. Maybe the foreign brands are different in this regard.

Long story short. After being on for just less than two days, the light
went out on its own accord at lunch time on Monday. Since I already had
an appointment at the dealer for this morning I visited anyway thinking
the code would have been stored. No code. I asked what might have
happened and they shrugged and said this just happens now and then.

I've never had an American car light the check engine light and then
have no code found. Not exactly confidence inspiring...

My Saturn has done that a couple of times. Whenever it misfires, the
check engine or service engine light will come on for a few days and
then go off. The first time I had my mechanic read the code and he
said a misfire on plug 3 (or something like that, it was years ago) He
cleared it and told me it would have gone away by itself. Sure enough,
a couple of years later, the car sat for several weeks and misfired
again. It ran fine and a few days later the light didn't come on.

Well, the light is back on again. Both times now it came on shortly
after fueling the car. I'm thinking there may be a connection. I will
see if it goes out again by itself and then if it comes on the next time
I refuel, I will have something more to tell the dealer tech.

Common problem with a lot of cars. That is why they tell you not to put any
more gas once the pump kicks off on auto-fill. The re-circ system does not
work properly with the tank over filled, light comes on. After a few more
miles, gas is burned and the problem is corrected and it takes some number
of cycles for it to go off again.

On my Buick, I have to drive about 3.5 miles for hte light to come on,
something like 10 cycles and it goes off again.

I don't fill past when the pump shuts off automatically and I have
filled this car for 57,000 miles with no prior problems. I can't
believe it is that. But who knows. The idle is a little slower than
normal a little rough, so something is not 100% that is for sure. If
light stays on for more than two days this time, back to the dealer it
will go for a scan.

Could stil be a venting problem. Get the code read. It should still be in
there for a while even if the light goes off.

Lat time it wasn't. That is the strange thing. The light was on for
about a day and a half and went off the day before my service
appointment. They dealer said no code was present.

I'd be betting on a bad sparkplug. If you have an autozone of aamco
around you they will read it for free. I invested in a scangauge II for
my elantra. A little costly but the real time monitoring and ability to
read codes is well worth the $160 I paid for it. The reason your code
went out last time before you took it to the dealer is because your car
completed 3 or 4 drive cycles without the problem present anymore. In
cases like that it won't store it any longer. It may even be bad gas
temporarily fouling a plug. Or a bad plug wire. When was the last time
you changed the wires and plugs? The stock and cheapo aftermarket ones
should be done yearly.

That is certainly possible. I have not yet changed either plugs or plug
wires. Changing such annually went out with the 1970s. Replacement of
the plugs is recommended at 98,000 miles and my experience of late is
that the platinum plugs will easily go 100K miles. Even my Chevy truck
gets 50,000 on a set of standard plugs and the plug wires were replaced
for the first time just last year after 15 years and 100,000 miles. And
I think I wasted my money as they weren't the problem which later turned
out to be a catcon that was plugging up.

I will run the Sonata for a few days this week and see if the light
stays on and try to stop at the dealer and see if they will check the
code without first having to have an appointment. It is a pain making
an appointment and then having nothing for them to look at.

That would be a terrible waste of money. In the past 30 years, I've not
gotten less than 60,000 miles from plugs and six years from wires. The
newer cars have gone 100,000 miles and my '91 Regal had the original wires
(seconds set of plugs) after 14 years and 160,000 miles. Ran as smooth as
the day it was new.
