Check Engine Codes

[T-Burd]

So, my check engine light came on suddenly this week. I took it to Advance Auto Parts and they gave me the rundown:

P0100 - Mass Air Flow
P0110 - Intake Air Temperature Sensor
P0440 - Emissions System

I'm guessing since these all popped up at once there is one piece that affects all three systems that has probably failed.

Any ideas?

I've got a '99 3.4L.

Thanks.

If I were in your position, I'd start with cleaning the MAF with dedicated CFC MAF cleaner, clear the codes, and see what happens from there. But I would guess that your MAF may be toast.

Think I sorted it. Went out this morning, and it wouldn't start. Battery was toast. Replaced the battery, and all is good. No more check engine lights.

Good to hear. Sometimes it is the simple things. Make sure all grounds are tight.
