Default How long does check engine light take to reset.

I filled up my tank the other day and realized this morning that the check engine light is on. I freaked out for a second, but I see now that my gas cap was barely screwed on. Like not threaded at all. I tightened it down and turned on my car on only for a second because I just arrived to work, and the light was still on. How long does it usually take before the light would go off.

I know that I need to get the codes read at a parts store, but I'm stuck at work and all I can think about is my poor s2000 in the parking lot. Please someone put my mind at ease before I have a panic attack.

Light won't go out once a code is tripped without clearing it. You could disconnect the battery and let it sit for 15 min or so to reset it. If it comes on again, you know you have an actual problem that isn't just the gas cap. You're fine

I'm new to Hondas, but in most cars, check engine lights, as long as they are resolved, will go out. You must first satisfy the monitors that the ecu requires per dtc.

If its a gas cap code you'll probably get a P1456 code.

Yes, get it checked first. It may be something a little more dire than just a loose gas cap.

You can clear your own code. There is a "clear a cel" DIY in the sticky section of this forum.

Sorry to not ease your mind.

You can disconnect battery or pull the ecu//fuse (while car is off) it will clear the code but the system wont be ready for ~50 miles

Evap is a two trip code. It will take a bit of driving but it will eventually clear itself out.

got the same warning for the exact same reason on my 04 pilot. took about 1.5 tanks of gas to clear (450 miles roughly) without me disconnecting the battery.

Southdakotas2k is right. If its an evap code, it will be a 2 cycle code to satisfy monitor criteria. It has nothing to do with mileage or time driving, but everything to do with temps, level of fuel in tank, how long the car is parked, etc..

An experienced tech can satisfy an ecu monitor in 5 minutes if he knows what the ecu is looking for.

As said before, have the codes read (though I suggest buying a cheap scan tool (20-40$) ) if it's P1456, clear it, Or just let it ride and see if it resolves itself. If its another code you'll have to dig a little deeper.

Reset fixed it for about 500mi or so. Came on again. Its a p1457 code which is a evap valve assembly. What kind of symptoms does it cause on a running engine? I miss a few cylinders every 100mi maybe. Its rare but shouldn't happen. Does the gas cap not being tight cause extra wear on the evap assembly? What exactly does the evap assembly do?
