Question about 2003 Hyundai Santa Fe
We took it to autozone and they put it on the computer the code read:BBH02S21 lambda at limit-rich condition, probable cause 881- fuel pressure too high,
882- fuel pressure regulator fault, 883- plugged air filter or exhaust, 884- failed injectors do you think any of these are the culprit?
Plugged air filter will result in too lean.not too rich. have the fuel pressure tested. overfuelling will result in the catalytic converter overheating.if the 02 sensor on the catalytic is no good,it will not sense unburnt fuel and the ecu will overfuel. check the air inlet hose and the airflow meter
