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

Частые симптомы

• Check Engine Light
• Possible oxygen sensor correlation issues between sensors on bank 1
• Reduced emission system accuracy
• Sensor agreement problems between upstream and downstream on same bank
• Emission control consistency concerns detected

Возможные причины

• Oxygen sensor accuracy differences on same bank
• Catalyst efficiency affecting sensor correlation
• Exhaust system issues between sensors
• ECU correlation algorithm fault for same bank sensors
• Sensor calibration differences on bank 1

Диагностика

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

Решения по ремонту

• Replace faulty oxygen sensor(s) on bank 1
• Address catalyst efficiency issues if present
• Repair exhaust system problems between sensors
• Update ECU correlation software for same bank
• Reset emission system adaptations on bank 1

Профилактика

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