‘chip’) with a current running through it.

Dividing the sensor vacuum and the vacuum from the intake manifold is a flexible silicon wafer (a.k.a. (On a forced-induction engine, the MAP sensor can be found on the intake tract before the turbo.) Inside the MAP sensor is a sealed chamber that either has a vacuum or a controlled pressure that is calibrated for the engine. Your intake may look different.The MAP sensor is typically located on the intake manifold, either next to or on the throttle body itself. It is located in your intake tube right after the air filter. The first thing you’ll need to do is locate the sensor. More oil is not better on an air filter.ĬRC Mass Air Flow Sensor Cleaner (DO NOT use carburetor cleaner or brake cleaner, those leave residue and will make the sensor in worse condition) Most problems are from 'oiled' element air filters such as K&N. Running lean can cause excessive combustion temperatures and lead to engine damage or destruction. This can cause the engine to idle funny and not get enough fuel which is also called running ‘lean’. If the engine doesn’t know how much air is coming in it doesn’t know how much fuel to inject into the cylinder. If the mass air flow sensor becomes dirty it can no longer tell the engine how much air is really getting in.

They are the vane meter and the hot wire our trucks have a hot wire sensor. There are two common types of mass airflow sensors in usage on gasoline engines.

The air mass information is necessary to calculate and deliver the correct fuel mass needed by the engine. A mass airflow sensor is used to determine the mass of air entering the engine.
