Check Engine Light
Check engine light came on and care started to shudder a bit. I found this thread and cleaned the MAF as described. The shudder seems to be gone, but the Check Engine Light is still on.
Or if the MAF was the problem and cleaning the MAF solved it (the shudder that was there is gone now), will the light go off on its own after a time or must it be manually reset by a tech?
Then once you get the code, post it here.
I called the dealer and asked them, they confirmed. Once the CEL comes on, if the problem is resolved and the car is cold started 3 times the CEL will go off if the error state does not return.
So, no codes needed this time, we got it. Thanks for this thread!




However, if a state emissions inspection is near, you'll likely fail.
The reason is that there are a dozen or so senors, which need to reset from 'not ready' to 'ready'.
These too will automatically reset, but only after driving at least 300 miles.
