Incorrect Fuel Sensor Readings
Why are Fuel Sensor readings not Updating/Wrong?
Fuel sensors are capacitive rods that need the following to function properly:
A GPS Device that has to be online for the fuel sensor to send data
Power Supply of approximately 7V. If a bluetooth sensor is used, ensure the battery is in operating condition.
Good Quality Fuel: We have seen impurities in fuel that tend to get stuck in the fuel rod and cause temporary short-circuiting. The impurities can be metallic waste, dust, mud, husk, water, rust, etc.
Connection with the GPS Device: The fuel sensor is not a standalone device. It needs to communicate with the GPS device and send data via the same. Ensure that the connection with the GPS device is proper and wires should not be tampered with. Check for short-circuiting and loose contact.
Recommendation if Tank is found dirty:
- Clean the tank and fuel sensor:
Ensure dust, water, metallic impurities, etc are removed and the tank itself is free of rust
- Tank should be waterproof:
This will prevent water from entering and mixing with the fuel. Rain and wet terrain can cause water to get into the fuel tank.
- Keep in mind the accuracy of the fuel sensor:This is for situations when you see the readings are in line but not accurate enough, refer to the accuracy as mentioned in the specifications.The image below is a depiction of dirt and metallic impurities collected inside the filter of the fuel tank. Such impurities will hamper the fuel sensor readings. Hence it is recommended to clean the fuel tank once every 6 months to ensure proper operation of the fuel rods.
