Mass airflow sensor Analysis

Image
Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine.  The mass air flow sensor measures the amount of air entering the engine or the  air flow . Mass Air flow Sensor (MAF) In modern cars, an intake air temperature sensor or IAT is built in the mass air flow sensor. There are few types of air flow sensors, however, modern cars use a hot-wire type. Let's see how it works WORK The Mass Air Flow Sensor measures the amount of air volume flowing into a car’s engine, and sends the Electronic Control Unit (ECU) a voltage that represents the airflow. Currently the most common MAF sensor is the plug-in hot wire type which is located inside the intake air duct between the air filter and the throttle body. This consists of a heating resistor, intake air temperature measurement resistor (for compensating intake air temperature), intake air  te

Engine misfires, common causes and remedies

Image
An engine misfires. It’s a sensation you instantly recognize but just as quickly block out. The engine stumbles for a moment and then regains its pace. Just as soon as the rpm settle down, though, the engine misfire reappears, and you’re stuck with the sinking feeling that accompanies all automotive problems beyond the shadow of your wisdom: “Something’s wrong.”  The sinking feeling is often followed by either, “This is going to be expensive,” or, “Why me/now/here?” All expected, but reasonable? What we recommend instead is, “How can I fix it?” Engine misfires can be caused by a list of faults, but there are a few suspects that occur more than others. The primary villains are simple – spark or fuel – usually manifesting in spark plugs, plug wires, the coil(s) or the fuel-delivery system. There are other more dire causes: computer or wiring problems, breakage in the rotating mass (pistons, rods, crank bearings), valves and the heads can fail or distort, cooling difficulties might

How do I get the check engine light to go off?

How to Reset a Check Engine Light Check engine lights go on when there is a problem in the engine or the emissions control system. You should always have the codes generated by your car's computer scanned and read so you can determine the cause. You can reset the light once you have fixed the problem. This article will tell you how to reset the check engine light in your vehicle. Method One of Two: Use a Code Scanner 1 Connect the scanner to the on-board diagnostic connector (OBD-II) under your steering column.  Turn your ignition switch to "On." Turn off all accessories. 2 Press the "Read" button on your scan tool to view the engine's error codes. Write down the code or codes in the order they were received for future reference and repairs if necessary. 3 Press the "Erase" button on your scanner to clear the error code. Clearing any codes present will turn off your check engine light. Some scanners
