HO2S Sensor Correlation Bank 2 Sensor 1 / Bank 2 Sensor 2

Частые симптомы

• Check Engine Light
• Possible oxygen sensor correlation issues between sensors on bank 2
• Reduced emission system accuracy on second bank
• Sensor agreement problems between upstream and downstream on bank 2
• Emission control consistency concerns detected on second bank

Возможные причины

• Oxygen sensor accuracy differences on bank 2
• Catalyst efficiency affecting sensor correlation on second bank
• Exhaust system issues between sensors on bank 2
• ECU correlation algorithm fault for bank 2 sensors
• Sensor calibration differences on bank 2

Диагностика

1. 1. Compare readings from bank 2 sensor 1 and sensor 2
2. 2. Test each sensor operation individually on bank 2
3. 3. Check catalyst efficiency and exhaust system between sensors on bank 2
4. 4. Verify sensor calibration consistency on bank 2
5. 5. Test ECU correlation calculations for bank 2 sensors

Решения по ремонту

• Replace faulty oxygen sensor(s) on bank 2
• Address catalyst efficiency issues on bank 2 if present
• Repair exhaust system problems between sensors on second bank
• Update ECU correlation software for multi-bank
• Reset emission system adaptations on bank 2

Профилактика

• Regular oxygen sensor correlation checks on both banks
• Address catalyst efficiency issues promptly on all banks
• Monitor sensor agreement within each bank separately
