P0101 Detects a performancefailure in the Mass AirFlow (MAF) sensor,such as when a MAFvalue is stuck in range.

This diagnostic isperformed using theIntake Flow RationalityDiagnostic (IFRD).IFRD calculatesmodeled values ofsensors from othersensors. The othersensors are theManifold Pressure(MAP) sensor andThrottle Position sensor(TPS).

These modeled valuesare compared againstthe actual sensorvalues to see if theyare similar. If they aresimilar, then the modelpasses. If they are notsimilar, then that modelis considered to befailed. Certaincombinations of modelpasses and modelfailures can beinterpreted to becaused by aperformance issue withthe MAF sensor. In thiscase, the MAFPerformance diagnosticwill fail.

When the value of theIAT signal in °C isdetermined, a delta iscalculated between thecurrent reading and theprevious reading. Theabsolute value of thesedeltas is summed overa number of IATreadings. The result ofthis summation iscalled a “string length”.

Since the IAT signal isanticipated to berelatively smooth, astring length of aparticular magnitudeindicates a noisy orerratic IAT signal. Thediagnostic will fail if thestring length is toohigh.
