Charge Air Cooler Temperature Sensor bank 1/2, Correlation

Частые симптомы

• Inconsistent temperatures between charge air coolers
• Check Engine Light
• Possible uneven boost between banks
• Reduced multi-bank turbo efficiency
• Bank-specific performance issues

Возможные причины

• Different sensor readings between bank 1 and bank 2
• One charge air cooler more efficient than other
• Bank-specific intercooler restrictions
• Sensor calibration differences between banks
• ECU correlation calculation fault

Диагностика

1. 1. Compare charge air temperatures between banks
2. 2. Test both temperature sensors operation
3. 3. Check for bank-specific intercooler restrictions
4. 4. Inspect intercooler efficiency differences
5. 5. Verify ECU correlation calculations

Решения по ремонту

• Replace faulty temperature sensor on affected bank
• Clear restrictions in affected intercooler
• Balance intercooler efficiency between banks
• Update ECU correlation software if needed
• Reset multi-bank turbo adaptations

Профилактика

• Regular multi-bank intercooler inspections
• Address bank-specific cooling issues promptly
• Monitor temperature differences between banks
