A MAP sensor, or manifold absolute pressure sensor, is a type of engine sensor that measures the amount of air pressure present in a vehicle’s intake manifold. This pressure reading is used along with engine speed (measured in revolutions per minute, or RPM) to determine engine load, which allows the vehicle’s engine control unit (ECU) … Read more
As you probably know, the internal combustion engine of your vehicle needs the right balance of air and fuel in its cylinders for a successful combustion to take place. This will generate the proper amount of power needed to satisfy the demands being placed on it by the accelerator. This is all managed by the … Read more
The camshaft position sensor (CMP) is just one of the many electrical parts found in a vehicle. We’ll go over what this component is, the symptoms of a bad camshaft position sensor, and what you can expect its replacement cost to be when it’s faulty. A lot of people confuse the camshaft position sensor with … Read more
You’ve probably been there before. While driving, your instrument cluster suddenly displays a “Tire Pressure Sensor Fault” message or warning light. But what exactly does it mean and how do you fix it? What is a Tire Pressure Sensor? A tire pressure sensor is a small computer located inside each tire. It is designed to … Read more
Here we’re going to discuss the following engine sensor: The oil pressure sensor (or oil pressure switch). I will be explaining what the functions of this sensor are and what symptoms may occur if this sensor malfunctions. How an Oil Pressure Sensor / Switch Works The main job of an engine oil pressure sensor is … Read more
When you look at the fuel gauge on your dashboard, have you ever wondered how it reads the level of gas in your fuel tank? Well, there is a special sensor in the fuel tank called a fuel level sensor which detects the gas level. And, because this is an electronic sensor, it is able … Read more
Though your car was running just fine the last time you drove it, it’s suddenly acting really strange. The idle may be surging, the car jerking while driving, and it might even stall out at a stop light. Your check engine light is probably on as well. Without plugging in a code reader, it’s a … Read more
In this article, we will go over one of the important sensors in the engine, commonly referred to as the “crankshaft position sensor”. Afterwards, you’ll understand its basic function, working principle, failure symptoms, and the replacement cost of this sensor. How a Crankshaft Position Sensor Works The internal combustion engine depends on the crankshaft for … Read more
The powertrain control module is the central computer of any modern vehicle. It communicates with all different kinds of sensors which exist in the vehicle. Based on the information it receives, the module can keep all systems of the vehicle functioning properly. One particular thing that the module watches closely is the engine load. The … Read more
The crankshaft position sensor electronically communicates with the engine control unit of a vehicle. This sensor keeps track of the crankshaft position and rotation speed. Once the engine control unit receives this information from the sensor, it will tell the fuel injector how much fuel to let into the internal combustion chamber. It will also … Read more
