10054E - Special Coverage (customer co-pay discontinued). The contacts on the fuel level sensor may wear prematurely. This wear could cause the fuel gauge to read empty after filling the tank and cause the malfunction indicator light (MIL) to illuminate. As the fuel level in the tank drops, the MIL may turn off and the gauge may display a reading; however, the reading may indicate a slightly higher level of fuel than what is in the tank. Eventually, as the contacts continue to wear, the fuel gauge will stop working and the MIL will illuminate continuously. If the condition occurs within the stated terms, dealers will install a new design fuel level sensor.
