Possible causes

  • Aged or damaged catalytic converter
  • Downstream oxygen sensor fault giving a wrong efficiency reading
  • Exhaust leak
  • Misfire or mixture fault overloading the catalyst

Recommended checks

  • Compare upstream and downstream oxygen sensor signals
  • Check for exhaust leaks
  • Check for stored misfire or mixture codes first
  • Verify catalyst temperature plausibility where available
