Is it necessary to replace a faulty fuel level sensor?
1 Answers
It is necessary to replace a damaged fuel level sensor. Below are the relevant details: 1. Sensor: The sensing part of a capacitive fuel level sensor is a coaxial container. When fuel enters the container, it causes a change in capacitance between the sensor housing and the sensing electrode. This change is converted by the circuit with precise linear and temperature compensation, outputting a 4-20mA standard signal to the display instrument. 2. Function: The sensor detects the position (height) of fuel in the container by utilizing the capacitance change between the sensor housing and the sensing electrode when fuel enters, and converts this change into a current variation.
