Does anyone know how to turn the check engine light off with out going to the dealer? i had a loose gas cap and they are telling me it will take 100 starts for it to turn off.

Usually goes off by itself in 4-5 days don't sweat it!!

Oddly enough it went out after 1 day. I gues if there was somthing actually wrong with the car it would stay on until it was fixed.

i had the same problem, simply disconnect the battery, wait 3 minutes , connect it again and the check light will reset.

Just took my '05 Santa Fe 3.5 in with the check engine light on...replaced a defective gas cap.

mine came on..........was a valve of some kind, not the gas cap

can you be more specific regarding the 'valve" /was it in the engine? a PCV valve? please let me know.thanks

I finally took mine in and it was that Valve you guys were talking about. It doesn't drive any different but it was annoying going on and off all the time.

the most common codes for Sante Fes are P0446 and P0449, which indicate problems in the evaporative emissions system, the two valves (solinoids, really) that usually cause this condition are the canister close valve, which is mounted to the charcol canister in the center of the vehicle, above the driveshaft on 4WD equipped models. The second is the purge valve, which is under hood. On 3.5s, you have to pull the engine cover, and its mounted in front of the throttle body, held to a bracket with a 10mm nut, with a electrical connector and 2 EVAP lines going to it. On 2.7 and 2.4s, I think its behind the intake manifold towards the driver's side.

Mine is on at 2200 miles. I unhooked battery for a hour. It's still on. I'll call the dealer. Guess I should of bought a toyota.

Update:
Just went to the store and it went off.......for how long.......who knows????

Still off- 5/17/05 :clap:

Trust me, toyota is doing poorly with reliability and they are making ugly cars as well. So is Honda and Nissan. I have had 5 Hyundais and they never gave me a problem.

04 Santa Fe with over 60,000 KM, no issues

Digging up this topic...

I just had the check engine light pop on in my 03 Santa Fe.

Autozone read the error as P0446-Evaporative Emission Control System Vent Control Circuit Malfunction

Now, I don't know if its coincidence or not, but the CIL appeared a day after I blew through a huge puddle (didn't realize it was that deep). Could this have done something underneath?

Also, I cranked the gas cap to make sure it was on. If this is the cause of the problem, how long does it usually take (days, miles?) to reset itself?

Thanks.

I had just resolved EXACTLY the same error code issue. Resolved @ Hyundai service center.

(a) Under warranty, basic 60k
(B) Under back seat, 2 positions are there, which has to be opened to reach the fuel-tank. Take out the fuel-filter and change in both the 2 meters, which give the fuel gauge. In my case the code appeared AFTER I noticed another anomaly. The fuel gauge (dashboard) started showing ZERO when reaching half-tank. REMEMBER to change both, as they are in serial.
© Underneath there's a connection, which has to be changed besides the evap. cannister.
(d) Under the hood, there's another sensor - which requires change.

Note - © and (d) has been well described in this thread. As for (B), not sure but might be unique for me, nevertheless rep. told me that P0446 always almost also requires this change.

In your case, depending on the Hyundai store you'll go - they might be honest enough to change all.

Thanks alot. I appreciate the info. I guess I'll book an appointment with the dealership. I'll update after.

Just an update...

Looks like it was, in fact, the gas cap. I made sure I tightened it after my last fill-up. About a hundred miles later the light turned off.
