MAF Sensor In Range But Higher Than Expected

on 2011 Lincoln MKX 3.7L V6 · AWD

What this code means

The MAF sensor signal is within the valid voltage range but consistently higher than expected by the PCM. This suggests the sensor is over-reporting airflow.

  • Black exhaust smoke
  • Poor fuel economy
  • Rough idle

Common causes

  • Contaminated MAF sensor
  • Faulty MAF sensor
  • Air filter housing not sealed properly
  • PCM calibration issue

Diagnostic steps

  1. Clean MAF sensor
  2. Verify air filter housing is sealed
  3. Check for TSBs related to PCM calibration
  4. Compare readings to specifications

Repair notes

Clean or replace MAF sensor. Ensure intake system is properly sealed.
