What is P0101?
P0101 indicates a problem with the Mass Air Flow (MAF) sensor circuit, meaning the sensor readings are outside the expected range for current engine conditions. This is a medium-severity powertrain issue that affects fuel delivery and engine performance, commonly triggered by sensor failures, intake leaks, or electrical problems. Based on real data, this code appears frequently in Honda Civic, Nissan Maxima, and Chevrolet Spark models.
Common Causes:
- Faulty or contaminated MAF sensor (most common cause)
- Intake air leaks after the MAF sensor
- Damaged or corroded wiring/connectors in the MAF circuit
- Dirty or clogged air filter restricting airflow
Symptoms:
- Check Engine Light illuminated on dashboard
- Reduced engine power or hesitation during acceleration
- Poor fuel economy and rough idle
- Engine stalling or difficulty starting
