Why a mass airflow sensor instead of a volume airflow sensor is used for an engine management?
Air changes its density with temperature and pressure. In automotive applications, air density varies with the ambient temperature, altitude and the use of forced induction, which means that mass flow sensors are more appropriate than volumetric flow sensors for determining the quantity of intake air in each cylinder.
What kind of engine does a Mazda F8 DOHC have?
The F8-DOHC is a DOHC F8 and basically a de-stroked version of the FE-DOHC displacing 1.8 L (1,789 cc). It uses the same exhaust cam, but a different intake cam with less lift and a long, single-runner intake manifold.
Where is the correct timing mark on a Mazda F8?
The information I have on the JF8 Engine fitted to these vehicles states that the camshaft is in the correct position when the notch on the rear belt cover is aligned with the ‘A’ mark. As a precaution, make sure you turn the engine over a minimum of 2 full turns to ensure there is no valve-piston contact.
What’s the purpose of the mass air flow sensor?
The basic purpose of the mass airflow sensor is to measure the amount of air that is going into the engine so your car can release the proper amount of gas into the engine, so the car is able to run correctly. What Happens If You Disconnect Mass Air Flow Sensor?
How does the MAF sensor work at idle?
The MAF sensor produces an analog voltage signal. This MAF signal’s DC voltage is directly related to amount of air the engine is breathing. Therefore, if the engine is breathing in more air at 2500 RPM’s that at an idle of 900RPM’s the voltage output will be greater at 2500 RPM’s than at idle.
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 are the timing marks on a Mazda F8 engine?

What does a MAF reading on an engine mean?
Also, remember that MAF is a reading of the amount of air entering the engine. If you have a backflow issues (high backpressure) or even a timing issue where the valves are not opening and closing at the correct time (slack chains, jumped timing), your MAF sensor readings will reflect this as well.
