Checking the resistance of the sensor

Check the resistance of both the fuel level sensors. The resistance across each sensor may vary between 12 ohms (full fuel tank) and 383 ohms (empty fuel tank).

HINT: The resistance of the left fuel level sensor can be measured between terminals #5 and #6 on the connector for the fuel level sensors. The resistance of the right fuel level sensor can be measured between terminals #6 and #7 on the connector for the fuel level sensors. 

Remedy as necessary.

• For further information about signals and other values, see Signal specification
• To access the connector for the fuel level sensors and to replace the fuel level sensors, see Left fuel gauge sensor and Right side fuel pump with level sensor .
