artscot79 Posted May 22, 2013 Share Posted May 22, 2013 this should help ult Code DefinitionThe Mass Airflow Sensor (MAF)measures the amount of air entering the engine and the Engine ControlModule (ECM) uses the information to determine the proper amount of fuelquantity and ignition timing. The P0101 trouble code is set when theECM detects a problem in the electrical circuit to the MAF Sensor. Mass or Volume Flow Circuit/Performance Malfunction Symptoms Check Engine Light will illuminate In some cases, there may be no adverse conditions noticed by the driver In other cases, there may performance problems, such as a lack ofpower on acceleration, "coughing," misfiring, and/or backfiring Problems idling Black smoke from the tail pipe and poor fuel mileage Other codes may be triggered by the Mass Air Flow Sensor problemsuch as Oxygen Sensor and/or Fuel Trim Lean/Rich codes (P0130/P0136,P0131/P0137, P0132/P0138, P0135/P0155, P0171/P0174, P0172/P0175) Common Problems Large vacuum leaks, split Intake Air Boot or PCV Hose, defective intake manifold gaskets Mass Airflow Sensor (MAF) Mass Air Flow Sensor circuit and or wiring problems Defective Barometric Pressure Sensor Dirty or contaminated Mass Air Flow Sensing wire or filament PCM software needs to be updated Quote Link to comment Share on other sites More sharing options...

johnH Posted May 22, 2013 Share Posted May 22, 2013 try disconnecting the maf sensor and see if that makes any difference...if you are not sure where it is located, find the air filter box. Head upstream and you will see a plug with two wires coming out. Unplug this (this is your maf) Quote Link to comment Share on other sites More sharing options...

artscot79 Posted May 22, 2013 Share Posted May 22, 2013 with these faults dont waste money buying a sensor take it to a dealer and have it checked yes youll pay a dealer fee but youll only replace one part instead of replacing half a dozen trying to trace the fault as you see theres many things that can cause the fault Quote Link to comment Share on other sites More sharing options...
