  • •Erratic fuel gauge readings (fluctuations while driving)
  • •Fuel gauge stuck at a certain level
  • •Warning light for low fuel illuminated incorrectly
  • •Check engine light illuminated (if related to fuel sensor issues)

Diagnostic Steps

  1. 1Scan for error codes using an OBD-II scanner to check for related fault codes.
  2. 2Inspect the vehicle’s fuel level sensor wiring for damage or disconnections.
  3. 3Verify the functionality of the fuel level sensor by measuring resistance with a multimeter.
  4. 4Check the vehicle’s fuel tank for proper operation and ensure the float mechanism is not stuck.
  5. 5Test the instrument cluster for proper function by running a self-diagnosis if available.

Solution

Solution

1. Preparation

  • Tools Required: OBD-II scanner, multimeter, basic hand tools (screwdriver set, socket set).
  • Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Accessing the Fuel Level Sensor
