Corsa mass air flow meter symptoms impala

MAF) sensor measures the volume of air entering the engine so the Engine Control Unit (ECU) can calculate how much gasoline the fuel injectors should deliver to each cylinder in order to create the proper fuel-air ratio. Sometimes, however, a malfunction in this little instrument can lead to big problems, usually resulting in very poor engine performance.A mass air-flow sensor is used on fuel-injected vehicles to tell the computer how much air is going into the engine. Discover why a mass air flow sensor must be removed in order to be checked with help from an auto mechanic in this free video on auto parts.Mass airflow sensor problems can cause a variety of symptoms from the annoying to the must repair. We'll discuss these in-depth on this page.

A check engine light often comes on due to a dirty airflow sensor (MAS). Learn the symptoms of an MAS that needs cleaning, and how to clean it.

Code P01- Mass Air Flow Sensor Circuit Range/Performance

MAF sensor may be hard to start or stall after starting. It may hesitate under loa surge, idle rough or run excessively rich or lean.

Check engine light faults relating to the Mass Air Flow Sensor are becoming less common, but do occur. The tricky thing with some of these types of faults is that you can have a mass air flow sensor concern without triggering the check engine light. A vehicle with a faulty manifold absolute pressure (MAP) sensor will usually display symptoms of a rough running engine during acceleration, deceleration or at idle.The manifold absolute pressure (MAP) sensor is a common component on modern fuel injection engines that vaporize gasoline by pumping fuel into the engine under high pressure.
