Before testing the Fuel Level Sensor, confirm the actual fuel level. For early models, locate the Fuel Level Sensor harness near the
Fuel Tank, while for later models, remove the middle seat and fuel pump access cover. Disconnect the battery's negative terminal, ensuring you have the stereo's anti-theft activation code, if applicable. Disconnect the Fuel Level Sensor's electrical connector on the fuel tank, then use an ohmmeter to check resistance. With a full tank, the resistance should be around 17.0 ohms, and around 120 ohms when empty. If readings are off, replace the unit. Note: This test can be done with the unit removed, checking resistance with the arm down (empty) and up (full). If replacement is required, early models need the fuel tank removed, while later models need the middle seat removed. Be cautious while handling the float. Disconnect electrical connectors, remove the screw, and separate the Fuel Level Sensor from the assembly. Installation is in reverse order.
