Check Engine sign-Code P202C ????

Hi,
I just got "CHECK ENGINE" sign yesterday. With OBD scanner. it is showing code "P202C". What is that and how to fix it? I cleared it once, but it came back. So it needed to be fixed somehow. Any help is appreciated. Thanks.

It means 0 out of 34 people had the codes, or knew that a search of the forum would reveal that others have posted codes.

The search tool is your friend. It can often get you answers much faster than 24 hours.

Other than that, the person who has the time and references will answer when it suits them - not you. We aren't here just to jump for your convenience.

On the other hand, dealers are there for that, and you can pay them for their time.

All I was requesting was a quick answer. If it offends you, I am sorry. I tried searching about P202C before posting it, but nothing came up. and what is wrong in asking? I knew all the suggestions you wrote. If you are not willing to help, don't do it. Why are you wasting your time typing all that?

BTW, Thank you dearly, Gondon for the answer.

Nothing at all wrong in asking. You didn't offend with that.

Your slap at the forum members who didn't jump fast enough to suit you was offensive.

And I typed all that in case your criticism stemmed from ignorance, and not from a display of petulance. Plainly, it was a waste of time.

YOu need to get the dealer to tell you whats REALLY wrong with your car.. unless you want to spend the rest of the time chasing wild guesses..

BTW.. You will never get a C/E light because you need to flush anything.

After reading all the posts, I flushed the coolant. The check engine sign is gone for now. It was not on all the time, as we turn off the car, the computer resets. But last few days, after I changed the coolant, it has not came back. May be a coincident. But it worked for now. I will check my MAF sensor, as suggested. Thankyou all.
