DTC Descriptor
DTC P0068
- Throttle Body Airflow Performance
DTC P1101
- Intake Air Flow System Performance
Circuit/System Description
The engine control module (ECM) compares actual airflow based on throttle position (TP) to a calculated airflow based on manifold absolute
pressure (MAP) sensor, and mass air flow (MAF).
Conditions for Running the DTC
DTC P0068
* The engine speed is greater than 800 RPM.
* The ignition voltage is greater than 6.0 V.
* The throttle actuator control system is not in reduced power mode.
* The DTC runs continuously when the above conditions are met.
DTC P1101
* DTCs P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0335, P0336 are not set
* The engine speed is between 400-7,000 RPM
* The engine coolant temperature (ECT) is between 69-127掳C (156-260掳F).
* The intake air temperature (IAT) is between -20 to +125掳C (-4 to +257掳F).
* The DTC runs continuously when the above conditions are met.
Conditions for Setting the DTC
The ECM detects that the actual airflow rate is greater than the calculated airflow.
Action Taken When the DTC Sets
* DTC P0068 is a type A DTC.
* DTC P1101 is a type B DTC.
