I have a 2001 Blazer ZR2 Widestance. Every once in a while, while driving long distances, I get a P0101 code. After a while the code will clear. I was able to get the code read at an AutoZone while the light was still on, and it read as a p0101. That's about all thehelp I got from them. I'm thinking that it has something to do with the MAF sensor? Help please!

Thats your MAF Sensor. It may be dirty, try getting some intake cleaner and spray it all over your MAF sensor. Sometimes dirty and grime could get on it causing the sensor to display that.

Do you have a cold air intake or a k&n drop in filter?

Have you installed or reoiled a K&N filter lately?

Yea the oil from the filter will get on the sensor causing poor performance and the error.

I've had a K&N OEM replacement "drop in" since January. I havn't recently re-oiled it.

Yea same problem i had so i replaced it with the stock one and used the intake spray and just drenched my maf sensor and the code went away and i recently contact K&N about the issue as well.

Symptoms didn't show up till 6 months latter for me to.

Leave the K&N in there and blast the inside of the sensor with brake cleaner to clean the oil off of the sensor filament.

Reset the computer and you will be good to go.
