P0101-00: (PCM - VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	MAF sensor system: Function malfunction
Detection condition	The difference between the intake air amount measured by the MAF sensor and the estimated intake air amount estimated by the MAP sensor is outside of the specified value.
Fail-safe	Not applicable
Possible cause	MAP sensor/IAT sensor No. 2 connector or terminal malfunction (see CONNECTOR INSPECTION .) MAF/IAT sensor No. 1 connector or terminal malfunction (see CONNECTOR INSPECTION .) MAP sensor/IAT sensor No. 2 incorrect installation (Refer to MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 2 REMOVAL/INSTALLATION (VIN Y) in service information.) MAF sensor/IAT sensor No. 1 incorrect installation (Refer to MASS AIR FLOW (MAF) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 1 REMOVAL/INSTALLATION (VIN Y) .) PCM connector or terminal malfunction (see CONNECTOR INSPECTION .) MAP sensor malfunction (Refer to MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION (VIN Y) in service information.) MAF sensor malfunction (Refer to MASS AIR FLOW (MAF) SENSOR INSPECTION (VIN Y) .) Air leakage from intake-air system Purge solenoid valve malfunction (Refer to applicable PURGE SOLENOID VALVE INSPECTION (VIN Y) in service information.) PCV valve malfunction (Refer to POSITIVE CRANKCASE VENTILATION (PCV) VALVE INSPECTION (VIN Y) in service information.) A non-genuine air cleaner or air cleaner cover installed PCM malfunction (Refer to applicable PCM REMOVAL/INSTALLATION (VIN Y) in the service information.
Repeatability verification procedure	Clear the DTC recorded in the memory. (see CLEARING DTC .) Start the engine. Access the following PCM PIDs using the M-MDS. ECT TP1 TP2 ENG_RPM Warm up the engine until the engine coolant temperature is 70°C {158°F} or more. Perform the following: Depress the accelerator pedal to increase the engine speed to approx. 5, 000 rpm. Release the accelerator pedal to decrease the engine speed to idle speed. Repeat Step 1 and 2 operations above three times in succession.
