I have replaced the Electronic Control Module (ECM), the mass airflow ... to see if the relays are applying voltage to the mass air flow sensor. These two wires are easily seen in a wiring diagram ...

The most common type of mass-flow sensor is the hot wire design ... Once the electronic control module (ECM) knows the amount of air entering the engine, it looks at these other sensors to ...

That's particularly true of the engine's Mass Air Flow (MAF) sensor. As part of the performance-boosting air intake system, the MAF monitors how much air is entering the engine, helping regulate ...

A mass air flow sensor is one of the numerous tiny widgets and gewgaws that make up a modern automobile's electronic fuel injection system. In the MAF's case, it tells the car's computer how much ...

With disposable towels, wipe away any loose dirt or dust from the MAF sensor, as well as all air ducts. Take your time ...

Principles of heat transfer are utilized by thermal mass flow sensors to determine the flow velocity of a fluid. Heat is carried from the sensor to the medium when the fluid passes across the sensor.

Add the sensor and sensor interface into a microprocessor ... ultrasonic, turbine, thermal mass flow, and coriolis flow meters. In module 4 you will learn the theory and practical application of ...

Affected components: mass air flow (MAF) sensor. Number of affected vehicles: At this time, GM has not disclosed how many vehicles are believed to be affected by this recall.
