Abstract
A method and control module for determining a sensor error includes a time-based diagnostic module generating a time-based diagnostic for a sensor and an event-based diagnostic module generating an event-based diagnostic for the sensor. A synchronizing module synchronizes the time-based diagnostic and the event-based diagnostic to obtain a diagnostic result. A fault indicator module generates a fault signal in response to the diagnostic result.
