DTC P0461 - Fuel Level Sensor Circuit Performance

  1. Perform On-Board Diagnostic (OBD) System Check. Read and record FREEZE FRAME and/or FAIL RECORDS data for each DTC set. Go to next step.
  2. If a vehicle speed sensor DTC is also set, diagnose it before proceeding. If a vehicle speed sensor DTC is not set, go to next step.
  3. Remove fuel level sensor from fuel tank. Ensure sensor arm moves freely. If sensor arm does not move freely, replace fuel level sensor. Retest system. If fuel level sensor is okay, go to next step.
  4. Connect an analog ohmmeter to fuel level sensor. As arm of sensor is moved, needle on meter should move smoothly. Replace fuel level sensor if operation is not as specified. Retest system. If operation is as specified, go to next step.
  5. Using an ohmmeter, measure resistance of fuel level sensor as arm is moved from empty to full positions. Resistance should be 120.5 ohms at empty position and decrease steadily to 17 ohms at full position. Replace fuel level sensor if operation is not as specified. If fuel level sensor tests okay, replace PCM. Retest system.
