DTC P0174 System Too Lean (Bank 2): DTC Detecting Condition

DTC DETECTING CONDITION

Item Detecting Condition Possible Cause
DTC Strategy
  • Fuel Trim Limits Exceeded
  • Poor connection
  • Relevant sensor/actuator
  • Air leakage
  • Improper fuel line pressure
  • PCM
Enable Conditions
  • 550rpm ≤ Engine speed ≤ 4000rpm
  • 60°C(140°F) ≤ Engine coolant temperature ≤ 115°C(239°F)
  • -10°C(14°F) ≤ Intake air temperatures 60°C(140°F)
  • 0° ≤ Throttle position ≤ 80°
  • 25kPa ≤ Engine load ≤ 90kPa
  • 1.5g/s ≤ Intake air flow ≤ 80g/s
  • Barometric pressure ≤ 72kPa
  • Vehicle speed ≤ 130km/h
  • System voltage ≥ 11V
  • Feed-back control state
  • No other diagnostic fault
Threshold value
  • Average of short term fuel trim > 1.2
  • Average of long term fuel trim > 0.8
Diagnosis Time
  • Continuous (More than 0.3 second failure for every 0.75 second test)
>MIL On Condition
