Mass Airflow (MAF) sensor measures amount of air entering engine at a given time to determine fuel delivery. MAF sensor information is used for fuel delivery calculations. MAF sensor produces a frequency signal which can be monitored with a scan tool.
Conditions for setting DTC:
Low frequency test
- Engine running.
- Engine run time greater than 0.4 second.
- System voltage greater than 8 volts.
- Conditions present for greater than zero seconds.
- MAF signal frequency is less than 10 Hz.
