Hyundai - Error Code P0101
Hyundai - Error Code P0101
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles that have a mass airflow sensor. The MAF (mass air flow) sensor is mounted in a vehicle's engine air intake tract downstream from the air filter, and is used to measure the volume and density of air being taken into the engine. This P0101 diagnostic trouble code (DTC) means that the Mass Air Flow (MAF) sensor or circuit is not within normal operating range.
Causes:
- Dirty/Failed MAF sensor
- Air intake leaks
- MAF sensor electrical harness or wiring problem
Symptoms:
- Check Engine Light
- Rough running engine
- Slightly less power
- Inconsistant idle
- Poor fuel economy
Diagnose & Repair:
- Check all MAF sensor wiring and connections to make sure they are in good working condition (not frayed, broken, or exposed wiring)
- Clean the MAF sensor wiring and connections of contamination such as dirt, dust, oil, etc.
- Check for any air leaks in the air intake system
- Check for any vacuum leaks downstream of the MAF sensor.
