Can a dirty Mass air flow sensor cause misfire?
Even a dirty MAF sensor can cause a lean code and/or misfire to occur. The engine may be stalling because it isn’t getting enough throttle opening.
What happens when a mass air flow sensor goes bad?
The mass air flow (MAF) sensor, part of your vehicle’s electronic fuel injection system, is responsible for calculating the total amount of air entering the engine. A faulty MAF sensor can cause your vehicle to run too rich or run too lean.
When does the PCM use the MAF sensor?
The PCM uses the MAF sensor signal when calculating how much fuel to give the engine—more air equals more fuel. There are several different types of MAF sensors found in different vehicles.
Can a bad MAF sensor cause engine problems?
More frequent stops at the gas station You get diagnostic trouble codes pointing to the MAF sensor On some vehicle models, the MAF sensor also informs the computer about air intake temperature and engine load (to control some automatic transmission functions). So a bad MAF sensor on these cars can cause an even wider range of symptoms.
Is the Ford mass air flow ( MAF ) sensor inside?
Ford has used a Hot-Wire type mass air flow sensor for many years that either comes with or without an internal air temperature sensor. If the MAF sensor has 6 wires, then this is a dead giveaway that it has the air temp sensor integrated inside.
What happens if you unplug the mass air flow sensor?
Q: Car runs with the mass airflow sensor unplugged. If you plug it in it will die if the car is running. If you unplug the mass air flow sensor the car will start. If you try to plug it in while it’s running the car will die. My car has 90000 miles. My car has an automatic transmission.
