Common Culprits Behind Nissan Juke P0101
- Contaminated or Faulty MAF Sensor: Accumulation of dirt, oil, and debris can compromise sensor accuracy.
- Vacuum Leaks: Even minute air leaks in the intake system can perplex MAF sensor readings.
- Wiring Complications: Damaged or corroded wiring connected to the MAF sensor can disrupt signal transmission.
- Obstructed Air Filter: A severely clogged air filter restricts airflow, leading to inaccurate MAF sensor readings.
- ECU Software Glitches: Outdated or buggy ECU software can misinterpret MAF sensor data.
