Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
IMPORTANT:
High resistance in the secondary fuel level sensor circuit may set this DTC. When inspecting for a deformed or warped fuel tank, measure the resistance of the suspect fuel level sensor at empty, with the sensor in the fuel tank, and again with the sensor removed from the fuel tank. The measured resistance values should be the same at empty. If the measured values are not the same, refer to Fuel Tank Replacement
.
Depending on the current fuel level, it may be difficult to locate a malfunctioning sending unit. The malfunction may only occur when the fuel level is full or near empty. The fuel sending unit may need to be removed for further diagnosis. A fuel level sensor that has an intermittent condition causes this DTC to set. Remove the fuel level sensor. Refer to Fuel Tank Module Replacement - Primary or Fuel Tank Module Replacement - Secondary in order to test the resistance of the sensors. The resistance of the sensor should change between 40-250 ohms. Replace the sensor if the resistance did not change or was out of range.
