#FORD F150 MASS AIR FLOW SENSOR PROBLEMS HOW TO#
Here’s a fantastic video on how to diagnose a bad MAF sensor using a multimeter from Ratchets and Wrenches on YouTube. There are other codes related to the mass air flow sensor as well, but these are the most common ones. Ford F150 P0102: MAF Sensor Circuit Low.The two most common trouble codes in relation to the MAF sensor are: This is great because it helps you narrow down the problem. If the MAF sensor has gone bad, it’ll trigger the check engine light and provide an OBDII trouble code.

A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture. Idle Issues– Your F150 may run rich or lean when idling, or it may also idle erratically.Here are the most common symptoms of a bad or failing MAF sensor: When the mass airflow sensor has gone bad, you’ll definitely feel it. And, most of the time they are right by the air box and easy to replace.įaulty Mass Airflow Sensor Symptoms: Ford F150 If you do determine that you need a new mass airflow sensor, they aren’t too expensive.
