Abstract
A fuel controller for an internal combustion engine includes a rotational speed sensor 4 for detecting a rotational speed of a cam shaft of the engine 1, a crank angle sensor 5 for detecting a rotational speed of a crank shaft of the engine 1, and a controller 7 for determining whether the crank angle sensor 5 is normally operated or not based on an output from the rotational speed sensor 4 and an output from the crank angle sensor 5. With this arrangement, the fuel controller can securely execute fuel control with high reliability by detecting the failure of various sensors relating to the fuel control.
