Luftmassenmesser prüfen

Andreas, hier mal die MAF DTC Liste der 2002er EU Corvette LS1 mit 6 Gang (ich habe leider kein stock HP-Tuners File von 2000):

Ich habe mich jetzt nur auf die MAF Codes beschränkt

DTC P0101: MIL on Second Error
DTC P0102: MIL on Second Error
DTC P0103: MIL on Second Error

Du müsstest demnach zumindest nach 2x auftreten des Fehlers die MIL sehen und einen oder mehrere DTCs
auslesen können.
