DTC DETECTING CONDITION

Item Detecting Condition Possible Cause
DTC Strategy Case 1
  • Signal plausibility with rich mixture (during catalyst purge after fuel cut-off)
  • Poor connection or damaged harness
  • HO2S contamination
Case 2
  • Signal plausibility with lean mixture (during fuel cut-off)
Enable Conditions Case 1
  • Coolant temperature >73°C (163°F)
  • Downstream O2 sensor operative readiness detected
  • Downstream O2 sensor pre-heating phase finished
  • 4g < Integrated Mass Air Flow in last Fuel Cut-Off
  • Downstream O2 sensor signal at end of last fuel cut off <0.3V
  • Integrated air mass flow in Part Load >150g
  • Minimum upstream O2 sensor voltage during Catalyst Purge phase >0.6V
  • Modelled catalyst temperature >400°C (752°F)
  • No relevant failure
  • 11V< Battery voltage <16V
Case 2
  • Downstream O2 sensor operative readiness detected
  • Downstream O2 sensor pre-heating phase finished
  • 12g < Integrated mass air flow since fuel cut-off begin <250g
  • No relevant failure
  • 10V< Battery voltage <16V
Threshold Value Case 1
  • Max. downstream HO2S <0.6V during catalyst purge after fuel cut-off
Case 2
  • Downstream HO2S >0.3V during fuel cut-off phase
Diagnostic Time Case 1
  • 3 valid fuel cut-off followed by catalyst enrichment phases
Case 2
  • 5 sec.
MIL On Condition
  • 2 Driving Cycles
RENDER: 1.0x

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
