Mass air flow sensor problems
Problems with mass air flow sensors are common in many cars, including BMW, GM, Volkswagen, Mazda, Toyota, Nissan and other brands. The sensor element could get contaminated or damaged.
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 problems with the air flow sensor.
