DTC P0101 DETECTION CONDITION AND POSSIBLE CAUSES

DTC P0101 MAF circuit range/performance problem
DETECTION CONDITION 
  • PCM monitors the mass intake air flow amount when the engine is running.
    • If mass intake air amount is above 50 l/s  for 5 s  and engine speed is below 2, 000 RPM  with engine running PCM determines that detected mass intake air flow amount is too high.
    • If mass intake air flow amount is below 8-59 l/s (1) , 6-58 l/s (2)  (The value depends on engine speed). for 5 s  and engine speed is above 1, 000 RPM  with engine running and throttle opening angle is above 50%,  PCM determines that detected mass intake air flow amount is too low.

Diagnostic support note 
  • This is a continuous monitor (CCM).
  • MIL illuminates if PCM detects above malfunction condition in two consecutive drive cycles or in one drive cycle while DTC for the same malfunction has been stored in PCM.
  • PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
  • FREEZE FRAME DATA is available.
  • DTC is stored in the PCM memory.
POSSIBLE CAUSE 
  • MAF sensor malfunction
  • Electrical corrosion in MAF RETURN circuit
  • Voltage drops in GND circuit
