MAF Sensor In Range But Lower Than Expected
on 2016 Ford Taurus 2.0L I4 EcoBoost · FWD
What this code means
The MAF sensor is providing a signal that is within the valid voltage range but consistently lower than the PCM expects for current conditions. This typically indicates reduced airflow detection.
Symptoms
- Check Engine Light
- Lean running condition
- Poor acceleration
- Rough idle
Common causes
- Dirty MAF sensor element
- Restricted air filter
- Intake air leak downstream of MAF
- MAF sensor degradation
Diagnostic steps
- Clean MAF sensor with approved cleaner
- Replace air filter
- Inspect intake for leaks
- Compare MAF readings to specifications
Repair notes
Clean MAF sensor. Replace air filter. Repair intake leaks.
