Modern electronic engine controls calculate the correct quantity of fuel for a given situation. Several sensors and actuators come into play, such as the mass air fuel (MAF) sensor and fuel injectors, and just as with any other car part, these sensors and actuators can degrade over time. If...
HOW DO YOU KNOW IF YOU’RE DRIVING WITH A CLOGGED FUEL FILTER? Here are five of the bad fuel filter symptoms to watch for: You have a hard time starting car. If the problem is the fuel filter, and it isn’t changed soon, you may find that your vehicle won’t start at all. Mi...
Typically, a gradual decrease in gas mileage over several years is not directly attributable to the ECM. This slow decline can often be a result of general wear and tear on the vehicle’s fuel systems, including components like fuel injectors, fuel pumps, and filters. As these parts age, ...
Based on that piece of information, the ECU determines the amount of gas that fuel injectors need to send to each of the cylinders. You should be careful about bad MAF sensor symptoms because a little malfunction in this device leads to poor engine performance. 3 Most Common Bad MAF Sensor...
There are quite a few sensors which control the engine and transmission. If one of the sensors, such as the MAF, MAP, TPS or speed sensors are sending improper signals to the computer, limp mode can activate. Failed fuel injectors, coil packs and worn out spark plugs can also cause it....
If the signal from the sensor is missing, there will be no spark and fuel injectors won't operate. The two most common types are the magnetic sensors with a pick-up coil that produce A/C voltage and the Hall-effect sensors that produce a digital square wave signal as in the photo abov...
