Intake Air Temperature (IAT) Sensor 1 bank 2, Signal too High

Частые симптомы

• Abnormally high primary air temperature readings bank 2
• Check Engine Light
• Possible insufficient hot air compensation
• Incorrect temperature-based engine protection
• Primary system performance limiting

Возможные причины

• Short to power in primary IAT circuit bank 2
• Failed primary IAT sensor bank 2
• Open circuit or high resistance in primary system
• ECU primary signal processing fault
• Primary sensor calibration error

Диагностика

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

Решения по ремонту
