hello I got both p0107 and p0100... I know that p0107 = map sensor. its been replaced.But what is po100. I found this===>MAF P0100 open circuit check sensor signal time period = 0 uS battery voltage > 10.5 V
Engine is running TRUE
Key on TRUE

but what does this mean? please help. My car symtoms are: itmakes 20psi but it does 15 a lag then the other 5

 

P0100

The ECM detects that the MAF Sensor parameter is equal to 0 Hz for greater than 0.5 second.

 

so in you honest opinion. how can i fix this. I traded my Maf with a ss sc and still the same code?

 

now I have no boost.

 

The maf from an LSJ will not work on the LNF. The frequency range is completely different

 

wtf!! no comment
you know i know **** about that ****

hope you can fix it soon

 

well I work on an autozone and for all cobalt I get the same part number maf. I was checking, could it be the sensor located on the cold pipe
(air charge sensor) that sensor could cause no boost.

 

Le5 and the lnf are the same exact maf I kno cus I've swapped mine with my buddys

 

If you free-rev it at idle does it surge?

 

MAF is the same as Z06 MAF.

 

Well I traded the Maf from my Grandpas 05 ls sendan and still the same problem. I then took out the intake tube, cleaned it (it was full of grease type dirt) put it back on and the freaking cel went off. who knew. well anyway thanks for confirming that all mafs are the same.
