Abstract:
1. A system comprising: an out of correlation (OOC) detection module that detects an OOC error between a first throttle position sensor (TPS) and a second TPS; an out of range (OOR) detection module that detects first and second OOR errors for said first and second TPS, respectively; an OOC counter that sets an OOC fault when an OOC count is greater than or equal to an OOC value; an OOR counter that sets first and second OOR faults when first and second OOR counts, respectively, are greater than or equal to an OOR value, which is less than said 000 value; and a control module that increments said OOC count, said first OOR count, and said second OOR count when said OOC error, said first OOR error and said second OOR error, respectively, occur and that sets at least one of said first and second OOR counts equal to said OOC count when said at least one of said first and second OOR errors occur after said OOC error.
