    All the codes refer to the 'front' (before the catalytic converters) sensors circuits having abnormal voltages.
    Those codes indicate that the computer detects that the engine is running too lean (not enough fuel) and/or that the bank 1 and bank 2 front oxygen (O2) sensors' circuits are faulty.You could have airflow sensor (MAF) problems, air intake leaks, or deteriorating or faulty O2 sensors.
