silverado oil pressure sensor replacement
How to replacement Silverado oil pressure sensor: Use the hand pump or siphon method to empty the fuel tank, remove the battery negative cable, remove the luggage compartment carpet, remove the fuel tank gasket retainer, pull out the wire connecting wire from the sensor, loosen the nut, pull out the fuel sensor upward and backward from the fuel tank, replace it with a new sensor, and install it in the reverse order of removal. The fuel pressure control valve is located at the end of the fuel return pipe. The fuel pressure sensor, also known as the fuel pressure regulator, is used to control the fuel pressure in the fuel circuit, maintain the constant oil pressure of the fuel injector, and send the excess fuel back to the fuel tank.
The fuel pressure sensor is mainly composed of three parts: pressure sensor, transmission circuit and electrical output interface. The basic structure of the voltage pickup is that the pressure change is induced by the strip resistance, the resistance change is amplified and converted into the pressure difference through the Wheatstone bridge structure, and then transmitted to the transmission circuit for filtering, amplification and other processing. The fuel pressure sensor detects changes in the oil pressure in the fuel lines. If it is damaged, the fuel pressure cannot be detected, and the engine computer cannot adjust the fuel pressure according to the working conditions, so the car will have weak acceleration and difficult starting. It's easy to change this. The oil pressure sensor is located a little above the oil pan. It should be said that this is true of all engines. If you change it yourself, first of all, be careful not to dirty your clothes. Oil stains are not easy to clean. Remember to wrap the thread of the oil pressure sensor you bought about 7.8 times with the material tape, then put it aside and unscrew the old oil pressure sensor on the engine. To prevent more oil leakage, quickly turn the newly purchased sensor wrapped with raw material belt clockwise
In the process of using the fuel level sensor, not only its installation method is very important to the user. The disassembly method of oil level sensor is also an indispensable knowledge for users. As the fuel level sensor inevitably needs to be replaced and maintained during use, it is easy to damage the fuel level sensor if the removal method is not known. What is the removal method of the fuel level sensor? Before removing the fuel level sensor, drain the fuel in the fuel tank with a manual pump or siphon. Remove the negative battery cable. Pull out the luggage compartment carpet and remove the fuel tank gasket retainer. Unplug the wire connector from the sensor. Loosen the cap nut and pull the fuel level sensor up and back out of the fuel tank. Install in the reverse order of removal. It should be noted that when installing the cover nut, two types of sealing rings should be worn, and the lug on the flange face of the sensor should face downward.
