Why does my Ford MAF sensor get dirty?
Bad gas mileage. Vehicle may idle rough and stall. Is My Ford MAF Sensor Just Dirty? MAF sensors have a tremendous tendency to get dirty and cause several headaches that may include: BAD gas mileage, higher emissions, and/or lack of power.
What happens when the MAF sensor goes bad on a F150?
F150 Bad MAF Sensor Diagnosis If the MAF sensor has gone bad, it’ll trigger the check engine light and provide an OBDII trouble code. This is great because it helps you narrow down the problem. The two most common trouble codes in relation to the MAF sensor are:

What happens if you have a vacuum sensor leak?
A MAP sensor vacuum leak can upset ignition timing and engine stability and efficiency. A vacuum leak can also prevent an EGR valve from opening, cause engine overheating, and increase harmful emissions. This type of leak can also affect the Positive Crankcase Ventilation (PCV) system.
What causes black smoke from the MAF sensor?
The MAF sensor measures the air going into the engine. If there is a leak on the pipes between the MAF sensor and the engine, there will be measured air lost. This will cause a wrong air-fuel mixture and, in most cases, a rich mixture. A too rich mixture will cause black smoke from the exhaust pipe.
