fuel level sensor a circuit low
Fuel level sensor a circuit low is the voltage from the instrument control unit, that is , 5V . If the voltage from the instrument in the past is 12V, this is the sensor . That one is also from the instrument . Some are from the vehicle body, and it is 0V , which is the low-level reference voltage.
This may be the oil pump fault , oil pipe , oil filter blockage , etc . the current car is controlled by the computer . Whenever your car encounters a problem , the on-board computer will remind you in a specific way , but the computer will use the specified code to indicate the fault. Each fault code represents an abnormality or fault of the car.
Different models may use different fault codes . When an error is reported, the owner can query the corresponding fault code , troubleshoot and handle the problem . It is recommended that the vehicle professional maintenance technician should complete it . If you want to clear the fault code by yourself , you should pay attention to the following knowledge.
It is necessary to clear the fault code after troubleshooting the vehicle . When clearing the fault code , it is necessary to clear the fault code according to the clearing method specified for the corresponding vehicle model . It must not remove the negative grounding wire directly to clear the fault code . Otherwise , it is likely to cause the following two problems: first , the control computer of some vehicle models will lose "experience memory". I believe everyone knows that many vehicle computers have the function of automatic memory. After removing the negative grounding wire of the battery , the useful data of engine operation stored in the random access memory will be erased , so that the performance of the vehicle will be poor for a long time after maintenance . Or the previous fault code may appear after driving for a short time . Second , it will also cause the loss of some functions of the car . For example, the audio lock is one of the more common examples . At this time , to restore the normal functions of the audio system , it is necessary to decrypt the audio . This process is very troublesome . If the car notes the fuel level sensor a circuit low , it is better to ask professional people to solve it.
