Condition
Some customers may comment on an illuminated check engine light shortly after a cold start with no engine performance concerns. Upon inspection,
DTC P1101 (Intake Air Flow System Performance) may be set. In some instances, DTCs P0068 (Throttle Body Airflow Performance), P0171 (Fuel
Trim System Lean Bank 1) and/or P0174 (Fuel Trim System Lean Bank 2) may eventually set as a result of the DTC P1101.
Correction
Verify the condition. If the diagnostics in SI for the conditions described above do not isolate a fault, reprogram the ECM with the revised calibration
that has been developed to address this condition.
Verify that the multiple diagnostic interface (MDI) that is being used is configured to the PC that will be used.
Warranty Information
For vehicles reprogrammed under the 8 year/80,000 mile (130,000 km) emission controller warranty, use the table above.
