HO2S Bank-2 Sensor-2 Heater Resistance

Частые симптомы

• Delayed bank 2 downstream O2 sensor activation
• Extended bank 2 catalyst efficiency monitoring
• Check Engine Light
• Possible slow bank 2 catalyst efficiency checks
• Reduced bank 2 emission system performance

Возможные причины

• Bank 2 downstream heater element resistance out of spec
• Aging bank 2 downstream O2 sensor heater
• Partial bank 2 downstream heater element failure
• Corroded bank 2 downstream sensor connections
• ECU bank 2 downstream resistance measurement fault

Диагностика

1. 1. Measure bank 2 downstream O2 sensor heater resistance
2. 2. Compare with manufacturer specifications
3. 3. Check bank 2 downstream connections for corrosion
4. 4. Test bank 2 downstream heater circuit
5. 5. Verify ECU bank 2 downstream resistance measurement

Решения по ремонту

• Replace bank 2 downstream oxygen sensor with bad resistance
• Clean or repair bank 2 downstream connections
• Replace faulty bank 2 downstream wiring
• Replace ECU if bank 2 downstream measurement faulty
• Reset multi-bank catalyst monitoring system

Профилактика

• Use quality downstream sensors for both banks
• Protect bank 2 downstream sensor connections
• Regular multi-bank catalyst system maintenance
