How to Replace Your Vehicle's Fuel Level Sensor
As the food of your vehicle, the fuel should be inspected at all times. You would not want to stop in the middle of the road just because you have insufficient fuel, right? Hence, the fuel level sensor is there to guide you. It allows you to have an accurate knowledge of the fuel level in your ride, so you will always be aware of your refilling schedule. If you want to change the old one, worry not! Here are the procedures and tools that will help you:
Difficulty level: Moderate
What you'll need:
- Marker or grease pencil
- Flat-head screwdriver
- Lubricating oil
- New fuel level sensor
Step 1: You must disconnect the negative ground cable first from the battery terminal in your vehicle. This can prevent any electrical problems or accidents throughout the process.
Step 2: Find the location of the fuel tank where the fuel level sensor is close to. You can find it via looking at the gas pump icon, which points to the position of the tank.
Step 3: Once you have located the fuel tank, draw labels at the top area of the tank next to the old fuel level sensor. You can use a marker or a grease pencil for this matter. From there you can see the three terminals of the sensor. The labels will serve as marks for the proper placement of the new fuel level sensor later on.
Step 4: This time, detach the three wires on the top area of the old fuel level sensor. These wires are the ground, power, and switch. To remove them, grasp each wire's connector that is fastened to the terminal of the sensor, and lift each wire away afterwards. A flat-head screwdriver can be used for removal of wires that are fastened by screws.
Step 5: Pull the gasket or the lock ring of the sensor away with the help of a flat-head screwdriver once again. You can apply a lubricating oil on the lock ring or the gasket while rotating it away to lessen the friction.
Step 6: You may now remove the old fuel level sensor. If it is fastened with screws, move it in a counterclockwise motion until it is released. The screwdriver can be of help also.
Step 7: After setting aside the old fuel level sensor, you can install the new one. Follow the marks you have drawn earlier. If your new fuel level sensor needs to be fastened with screws, turn the fasteners in a clockwise motion this time.
Step 8: Reattach the gasket or the lock ring that you have removed earlier to your new fuel level sensor. Make sure that it is tightly secured.
Step 9: Reconnect the three wires that you have detached as well. If the wires are needed to be fastened with screws, do so with the help of the screwdriver once again.
Step 10: You may now re-establish the connection of the negative ground cable and the battery terminal.
Step 11: Turn on the engine in order to have a test drive. This will determine the efficiency of your new fuel level sensor.
