Patent ID: 7997251

Claim:
An engine control system, comprising: a status determination module that determines states of first and second throttle position sensors (TPSs), wherein a fault state includes when one of the first and second TPSs is one of outside of a predetermined range and out of correlation with the other of the first and second TPSs, for greater than a first predetermined period; a throttle actuation module that opens a throttle when an engine manifold absolute pressure (MAP) is less than a predetermined MAP threshold, at least one of the first and second TPSs is in the fault state, and the other one of the first and second TPSs is within a second predetermined period from transitioning to the fault state; and a failure counting module that increments a failure count when at least one of the first and second TPSs is in the fault state, and the other one of the first and second TPSs is within the second predetermined period from transitioning to the fault state.
