Charge Air Cooler Temperature Sensor bank 1, Signal too High

Частые симптомы

• Abnormally high charge air temperature readings
• Check Engine Light
• Possible reduced boost due to perceived hot air
• Incorrect temperature-based engine protection
• Possible performance limiting

Возможные причины

• Short to power in charge air temperature circuit
• Failed temperature sensor
• Open circuit or high resistance
• ECU signal processing fault
• Sensor calibration error

Диагностика

1. 1. Check charge air temperature signal voltage
2. 2. Test for shorts to power in sensor circuit
3. 3. Measure sensor resistance and circuit continuity
4. 4. Inspect for open circuits or high resistance
5. 5. Verify ECU signal processing

Решения по ремонту

• Repair shorted charge air temperature wiring to power
• Replace faulty charge air temperature sensor
• Repair open circuits or high resistance issues
• Update ECU software if processing faulty
• Reset turbo temperature adaptations

Профилактика

• Protect intercooler sensor wiring from damage
• Regular circuit continuity checks
• Address abnormal high temperature readings
