Conditions for Running the DTCs



* DTCs P0102, P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0128, P0335 or P0336 are not set.



* The engine is running.



* The engine coolant is between 69 and 127掳C (156 and 261掳F).



* The intake air temperature is between -20 and +125掳C (-4 and +257掳F).



* The DTC runs continuously when the above conditions are met.



Conditions for Setting the DTC



The engine control module (ECM) detects that the actual measured airflow from the MAF, MAP, and throttle position sensors is not within range of



the calculated airflow that is derived from the system of models for greater than 2 s.



Action Taken When the DTC Sets



DTC P0101 is a Type B DTC.



Conditions for Clearing the MIL/DTC



DTC P0101 is a Type B DTC.



Diagnostic Aids



* A steady or intermittent high resistance of 15 ohm or greater on the ignition voltage circuit will cause the MAF sensor signal to be increased



by as much as 60 g/s.



* Depending on the current ambient temperature, and the vehicle operating conditions, a MAF sensor signal circuit that is shorted to the IAT



signal circuit will cause the MAF sensor signal to be skewed or erratic. Additionally, it may cause a rapid fluctuation in the IAT Sensor



parameter.
