check engine light

justincase · 01-27-2006, 08:56 PM

My check engine light came on today on my 98 firebird formula after changing the main belt.

The belt is on fine and all my gauges look alright. I ran the car down the road to check it and the light didn't come on until about 5 minutes when I did a 0-60 check at wide open throttle

What could be causing this? I checked all the connections onto the maf and the intake.

Take it to AutoZone and have them read the code for you.

Then report back to us what the code is.

Until then...not a whole lot we can do to help. Too many variables.

yea, thats what I was thinking

just wondering if anyone had a similar problem after changing belts and could give me a heads up

I'll run it to autozone in the morning

the code is p0102 which refers to the maf and the vaf saying the have "low circuitry"

what exactly does that mean?

To get to the belt did you removed the airbox lid right?

Did you remember to get all the wires reconnected?? One of them is the MAF.

Yea, I had to take the airbox lid and maf off, but I hooked everything back up fine, checked the connections and they also look fine.

If the maf wasn't hooked up right wouldn't the car run bad? Car's running fine.

Did you maybe accidentally clip one of the sensors in the MAF?

P0102 - Mass Air Flow (MAF) Sensor Circuit Low Frequency. Some things to double check from my manual, '98 might be a little different:

Engine sensor fuse
Poor connection @ MAF or sensor harness
Misrouted sensor harness/wire insulation
Any unmetered air sets P0102 - Vacuum leak, PCV leak, Oil dipstick tube not fully seated, Oil cap loose.
