P1102 - MASS AIR FLOW SENSOR IN RANGE BUT LOWER THAN EXPECTED

Description:  This DTC sets when the air flow is less than the calibrated threshold based on the engine speed and torque.
Possible Causes: 
  • Damaged mass air flow (MAF) sensor
  • Leaks or restrictions in the intake air system and charge air cooler (CAC)
Diagnostic Aids:  The presence of this DTC may indicate that the vehicle is operating in derate mode and may experience a loss of power.
When the RPM is 400 RPM to 3500 RPM the air flow should be greater than 0 to 210, air flow less than the minimum threshold value indicates a concern.
