CCU 000096.03 — Fuel Level Sensor Circuit Voltage High. High Voltage in Fuel Level Sensor Circuit

CCU 000096.03 (CCU 96.03)

Code: 000096.03

Shortcode: 96.03


This error indicates that the fuel level sensor’s circuit has detected a voltage higher than normal, suggesting an open circuit. This condition might be due to a faulty sensor, poor connection, or damage to the wiring.


Function of the fuel gauge or related systems may be degraded, potentially leading to inaccurate fuel level readings.


  • Inspect Wiring and Connections: Check for any disconnected, damaged, or corroded wiring and connectors in the fuel level sensor circuit.
  • Test the Fuel Level Sensor: Use diagnostic tools to test the functionality of the fuel level sensor to ensure it is operating within specifications.
  • Replace Faulty Components: If a fault in the sensor or wiring is confirmed, replace the damaged parts.


Regular inspection of sensor connections and wiring can prevent this issue from affecting vehicle operation.
