Alright, I am in a huge hurry...need to get to Jacksonville tonight, and I have to leave asap. This morning, I removed my air filter to clean it, and before putting it back on, I turned on my car. I noticed the Check Engine light came on, and remembered I hadn't replaced the filter, so I turned off the car thinking it would go away once the filter was back on. Well, it didn't. My brother told me to disconnect the battery for a bit, which I did, but the light is still on. Now, it was never on before this morning, so I assume it happened when I turned the car on without the filter in place.

Can anyone please tell me what the problem might be, and how I can fix it. Like I said, the sooner the better, because I have to get the hell outta here. Thanks.

 

I unplugged the temp sensor at the front face of the filter in order to remove the filter. But I have cleaned my filter before without this problem. I'm not sure if I turned my car on last time before replacing the filter though.

 

@Steve: I did, no difference

@Gabe: That's what my brother said it could also be, but what could've gotten in there? If it is a dirty MAF, can I drive with it like that, or will something else get nutty?

Yeah, it drives fine, and I can't tell a difference, but you never know. Reset what? Need some instructions for that.

 

As far as I can tell, yes. No difference. The first thing that crossed my mind was that the ecu was looking for the air temp, and since it was disconnected, the check engine light came on. That's why I thought it would go away once the cable was connected. But when it stayed on, I figured something had to be reset, but I don't know why. I guess the battery disconnect didn't work. What else can I do? I'm also thinking about sticking around tonight, and going to JAX early tomorrow morning, to get this thing cleared up.
