What happens if the mass airflow sensor is bad?
The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Toyota Camry’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Camry’s ECU.
What are the causes of code p0330?

What does the MAF sensor on a Toyota do?
The MAF sensor’s job is to measure the amount of air entering the engine (when the engine is running) and transmit this info to your Toyota’s fuel injection computer. The computer then uses this air flow measurement, along with other sensor inputs, to inject the correct amount of fuel into the engine.
What can cause a Mazda air flow sensor to fail?
For example, in some Mazda Skyactiv engines, a failed mass air flow sensor could cause the engine to crank but not to start. An improperly installed or collapsed air filter can cause the air flow sensor to fail sooner. Over-soaking a washable air filter can also cause troubles with the air flow sensor.

What happens if the MAF sensor on a Jetta goes bad?
A bad mass airflow sensor can leave your Volkswagen Jetta’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Jetta’s ECU.
How to test the 5 wire mass air flow sensor?
The most common way to test the 5 wire VW Mass Air Flow (MAF) sensor is just to unplug it with the engine running. If the MAF is bad (either because it’s not producing a signal or producing an erratic one), the car’s idle will return to normal and the car will seem to run fine.
What are the symptoms of a bad MAF sensor?
Here are the most common symptoms of a bad or failing MAF sensor: Idle Issues – Your Jetta may run rich or lean when idling, or it may also idle erratically. A rich condition is when there is not enough air relative to the fuel in the air/fuel mixture.
