GM fuel level sensor to gauge wiring diagram
The fuel level sensor is a tedious process, and many people are worried about it. Here is a detailed explanation of the installation of the fuel level sensor carefully prepared for the general public. Installation instructions for fuel level sensor
First: put the gasoline clean, then rinse it with water two to three times, and install it according to the following steps.
1. Positioning
The principle is generally in the middle of the fuel tank, avoiding the position of the original oil float.
2. Clean the dirt at the opening of the fuel tank. Remove the oil stains on the installation position of the fuel tank
3. Drilling
Clamp the 50mm metal hole drill with a hand electric drill, connect the power supply to drill in the middle of the positioned fuel tank, (note that the speed is not fast, stop when it is about to drill through, and use a screwdriver and needle-nose pliers to peel off the metal to be drilled. down to avoid it falling into the tank)
4. Clean up
Use a shrink file to remove the burrs from the opening. Put a magnet with a wire into the fuel tank, and suck out the iron chip.
5. Take out the sensor customized by the manufacturer according to the vehicle model. Remove the protective cover of the float, and use a screwdriver to remove 5 mounting screws and 5 self-tapping screws.Separate the sensor from the mounting flange.Check the O-ring of the flange. If it is complete, place it on the open hole.
6. Fixed
Use an electric drill to clamp a 2mm drill bit, and drill holes in the 5 grooved holes of the mounting flange (to penetrate the fuel tank), apply metal sealant to the 5 self-tapping screws respectively, and fasten the flange to the fuel tank . Mount the sensor on the flange and tighten with 5 screws.
7. Sealing
Use metal sealant to seal the junction of the flange and the fuel tank.
8. Wiring
Connect the corresponding colored wires, and wrap the joints with black tape. Select line sleeves. To route the line, go to the girder on the car.Fuel tank fuel level sensor output mode.The fuel tank oil level sensor has two output modes, electrical signal and physical signal.
The sensing part of the capacitive oil level sensor is a coaxial container. When the oil enters the container, the capacitance between the sensor housing and the sensing electrode changes. This change is converted by the circuit and performs accurate linear and temperature compensation. , output 4-20mA standard signal supply display instrument.
