Re: Maf P10201
Whenever possible it is helpful to post the year and model Grand Prix you have. The DTC is erroneous as typed. Should be a P0101 which is MAF range/performance problem. The other common DTC of P0102 is MAF operating below frequency of 1500 hz. Low frequency.
Was this MAF sensor new or used (reman)? Or do you have both DTCs?

Re: Maf P10201
Did you have this code before you replaced the MAF, and if so, did you have the codes erased after replacing the part? If not, the computer doesn't know you replaced it and it's an old stored code.

Re: Maf P10201
Did you check the electrical connector to the MAF. At least check for the PCM 5 volt low reference signal at the input. It is possible the MAF sensor you got is bad, wiring from MAF output to PCM module or the PCM module itself. In many cases on reocurring MAF DTCs you may have to go through more than one or two MAF sensors until you get a good one. When I had a similar issue I went to a salvage yard and got a pull/used one. Make sure it matches your year. '99 and up. One from a '97/'98 SII 3800 engine will not work properly.
Also, check the throttle body intake for no obstructions and that the input screen is clean and present.

Re: Maf P10201
No. Just remove the rubber intake ducting at the front of the throttle body. Screen will be at the input of the throttle body. Can't miss it unless someone removed it.
