How do you check the mass airflow sensor on a Ford mass air flow sensor?

Check the MAF Sensor Turn the engine and ignition off. Attach the positive probe of an ohmmeter to the terminal on the MAF marked SIG, and the negative probe to the terminal marked GND. Take a reading from the ohmmeter — damage to the hot wire element will be indicated by an open circuit. Click to see full answer. Subsequently, one may also ask, what happens if I unplug my MAF sensor?If you disconnect the mass airflow sensor, then the car should keep running and still be able to start normally. This means that if your mass airflow sensor dies completely, then your car will stay running and surprisingly the car might run better without the mass airflow sensor.Also, what will a bad mass air flow sensor cause? Symptoms of a bad mass air flow sensor As a result, a bad mass air flow sensor causes various driveability problems, including a no-start, stalling, lack of power and poor acceleration. In addition, a faulty mass air flow sensor might cause the Check Engine or Service Engine Soon light to come on. Then, can you drive with a bad mass air flow sensor?
