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?
