Mass or Volume Air Flow 'B', Circuit Implausible Signal - Air Flow too High

Частые симптомы

• Check Engine Light
• Unrealistically high air flow readings from MAF sensor B
• Possible incorrect fuel mixture calculations
• Erratic engine operation
• Secondary air flow measurement accuracy issues

Возможные причины

• Faulty MAF sensor B output indicating too high flow
• Sensor contamination or damage affecting readings
• Wiring issues causing signal corruption
• ECU signal processing fault
• Intake system issues affecting sensor accuracy

Диагностика

1. 1. Check MAF sensor B signal readings
2. 2. Compare with realistic air flow expectations
3. 3. Test for sensor contamination or damage
4. 4. Inspect sensor wiring for issues
5. 5. Verify ECU signal processing logic for secondary sensor

Решения по ремонту

• Clean or replace faulty MAF sensor B
• Repair signal wiring issues for secondary sensor
• Address intake system issues if present
• Update ECU software if processing faulty
• Reset air flow system adaptations

Профилактика

• Regular secondary MAF sensor maintenance
• Protect secondary intake system from contamination
• Address unrealistic secondary air flow readings
