摘要： An accelerator position sensor (APS) includes a transmitting coil generating a magnetic field, a coupler controlling the magnetic field generated from the transmitting coil, a receiving coil receiving the magnetic field generated from the transmitting coil to generate a predetermined frequency, and a signal processor calculating rotation information of the coupler using the frequency received from the receiving coil and outputting displacement values of an accelerator pedal. With the APS, a guarantee signal can be generated only through the receiving coil and precise measuring values can be achieved.

摘要： A method of diagnosing failure of fuel level sensors includes a first measuring step of measuring voltages from first and second failure detection terminals; if the voltage is higher than a reference, diagnosing the voltage as “high,” and if the voltage is lower than a reference, diagnosing the voltage as “low;” and if the voltage is neither high nor low: a second measuring step of receiving the voltages from the first and second failure detection terminals; calculating and storing a difference between the voltages of the first and second failure detection terminals; determining whether an amount of fuel is reduced; if the amount of fuel is reduced, calculating a difference between voltage signals of the first and second failure detection terminals; determining whether the voltage difference before and after the amount of fuel was reduced are identical; and if the voltage differences are identical, returning to the first measuring step.
