Is it ok to drive my car once the check engine light turns off?
I drive a 2016 Honda Civic. A couple days ago my Check engine Light turned on. It turned off today. I got it checked and the code was P0326, a knock sensor problem. Should I get it checked even though the light turned off?
It should still be under warranty - at least the mandatory federal emissions warranty, if you are in the US. Definitely get it checked out. The knock sensor is important for NOx emissions control and for protecting the engine from damage at high throttle. It is safe to drive it normally; not so safe to floor it.
Its ok.
Get it fixed.

OK if the light went out. Maybe you got some bad gas or exceeded the car's weight limit. Leave Fat Mary and her other triplets at home from now on, or don't carry a pallet of bricks for them again.
Likely a case of bad gas. If it comes on again, take it to the dealer. For now, drive the car.
Hi so the check light indicates there's an issue which needs to be diagnosed. Failure to do anything about it will at some stage switch into the Limp HOME mode.
I'd just drive if the motor isn't misfiring and see if the light and same code come back. If it does then go to a mechanic.
- Check engine light, open door light, and batterie light all came on and won't go off? 2000 Honda Odyssey I already had the altinator replaced it a month old. The batterie almost a year old. Would the belt need be changed or something else?
- Test light on positive lead on starter relay comes on when the motorcycle is off, when bike key is turn on, test light is off? Does this mean starter relay is bad? I'm trying to diagnose my electrical problem on a honda cbr f4. The lights turned on but when I tried to start bike all power shut off and now nothing powers on.
- After replacing our car battery, our remote starter just turns and turns without actually starting the car? My wife has a 2010 Honda Fit and we just had to replace the battery. We got a remote starter installed from Best Buy in either 2010 or 2011. But after the recent battery replacement, the remote starter responds by just cranking and not starting. It does like three sets of cranking before stopping. I don't remember the brand of remote starter, but anyone have any insight of what I need to do?
- Check engine light turns on for a few days and then turns off for weeks/months? Code P0420 on a 2004 Honda Civic Hybrid? Over the last year my check engine light has come on about 3 or 4 times for a few days at a time and then turns off again for a very long period of time. I know the code means my catalytic converter is below threshold but why would it turn off? Could it be something else? Should I look into replacing it or wait it out? Any advice is appreciated!
