DTC Information: DTC Detecting Condition

Item Detecting Condition Possible Cause
DTC Strategy
  • Plausibility check during shift of lambda set point to rich or lean (after P2096-00/P2097-00 detection)
  1. Poor connection or damaged harness
  2. Rear HO2S
Enable Conditions
  • No fuel cut-off
  • No full load phase
  • No catalyst overheating protection
  • Battery voltage is between 11V and 16V.
Threshold value
  • Downstream HO2S signal voltage is lower than 0.75V when lambda set point is equal to 0.80.
  • Downstream O2 sensor signal is too low.
Diagnosis Time
  • 7 seconds after lambda set point shift to corresponding side
MIL On Condition
  • 2 Driving Cycles
