Conditions for Running the DTCs
* DTCs P0102, P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0128, P0335, P0336 are not set.
* The engine speed is between 450-8,000 RPM.
* The IAT Sensor parameter is between -20 and +125掳C (-4 and +257掳F).
* The ECT Sensor parameter is between 70 and 125掳C (158 and 257掳F).
* This DTC runs continuously within the enabling conditions.
Conditions for Setting the DTC
The engine control module (ECM) detects that the actual measured airflow from the MAF, MAP, and TP sensors is not within range of the
calculated airflow that is derived from the system of models for more than 0.5 s.
Action Taken When the DTC Sets
DTCs P0101 and P1101 are Type B DTCs.
Conditions for Clearing the MIL/DTC
DTCs P0101 and P1101 are Type B DTCs.
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. To pinpoint this condition perform a voltage drop test on the circuit.
* Any type of contamination on the MAF sensor heating elements will degrade the proper operation of the sensor. Certain types of
contaminants act as a heat insulator, which will impair the response of the sensor to airflow changes. Water or snow can create the opposite
effect, and cause the signal to increase rapidly.
* 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 increase or decrease the MAF sensor signal that is interpreted by the ECM. Additionally it may cause a rapid fluctuation in
the IAT Sensor parameter.
* A skewed or stuck engine coolant temperature (ECT) or IAT sensor will cause the calculated models to be inaccurate and may cause this
DTC to run when it should not. Refer to Temperature Versus Resistance (See: Powertrain Management/Computers and Control
Systems/Specifications/Temperature Versus Resistance).
