Why does the automatic transmitting fail? Leakage problems in automatic transmissions Repair, revision, and renewal of automatic transmissions Most drivers are unfamiliar with automatic transmissions. The most drivers know little about automatic transmissions. They only know how to shift to the "D", "R" and "P" positions to allow the vehicle to go forward or reverse. Although they are...
What are engine sensors? What is the purpose of sensors in vehicles? What sensor can be used to detect which engine fault?Computers are only capable of performing the tasks that they are programmed for. An engine control computer for a vehicle (also known as an ECU or Powertrain Control Module) is programmed so it can act on data...
What is an engine-air temperature sensor (IAT), you ask? How does the intake temperature sensor work? What are the causes and symptoms of an air temperature sensor malfunction?
The Intake Air Temperature Sensor (IAT), measures the temperature of the air entering an engine. This data is used by the engine computer (PCM), in order to determine air density. It...
What does the engine cooler temperature (ECT-) sensor do? What happens when the water temperature sensor malfunctions? What are the symptoms for a coolant sensor malfunction? How to replace the temperature sensors ?....The engine coolant temp (ECT) sensor monitors the engine's internal temperature. It is a very simple sensor. It is used for measuring the coolant temperature inside...
What is an Air Flow sensor (MAF)? What does the MAF sensor do? What are the MAF sensor malfunction codes and symptoms? How to clean MAF sensor ?....
Two types of Mass Air Flow Sensors are used in multipoint injection systems. They are hot wire and hot films. Although their designs are slightly different, both types measure the volume...
What is a Manifold Absolute Pressure (MAP) Sensor? What is the MAP sensor? What is the MAP sensor's function? What are the symptoms for MAP sensor malfunctions? What are the types of MAP sensor fault codes?The Manifold Absolute Pressure Sensor, MAP / Manifold Absolute Pressure, is one of the key sensors used to detect engine load. The sensor...
What is a Vane Air Flow sensor (VAF)? How does the VAF Sensor work? What is the purpose of the VAF sensors? What are the symptoms of a VAF sensor malfunction?
Multi-point electronic fuel injection engines use air flow sensors. The computer that controls the amount fuel being sent to the combustion chamber (or ECU) is responsible for...
What is a direct gasoline injector engine? How does it work? What are the main advantages and problems with GDI TSI or FSI engines ?
Direct Gasoline injection (Gasoline Direct injection /GDI) is a fuel injection system that injects gasoline directly to the combustion chamber. There is one fuel injector per engine cylinder, as with engines with Multi Point...
