Patent ID: 8754764

Claim:
A controller for determining whether a previously-detected, vehicle pressure-sensor malfunction still exists, the controller comprising: an electronic, non-volatile memory; and an electronic processing unit connected to the electronic, non-volatile memory, the electronic processing module including, a malfunction monitoring module configured to monitor the operation of a pressure sensor and generate a first fault signal if the pressure sensor outputs a signal that is outside of a first pre-determined range, the first fault signal containing first fault information and configured to cause at least one of a first tell-tale indicator to be activated and a first vehicle control system to modify its operation from a first operating state to a second operating state, a failure handling module configured to cause first drive cycle information and the first fault information to be stored in the electronic, non-volatile memory, and a signal checking module configured to retrieve the first drive cycle information and the first fault information from the electronic, non-volatile memory and perform a first signal check on information from the pressure sensor by comparing an output of the pressure sensor to a second pre-determined range narrower than the first pre-determined range, the pressure sensor passing the first signal check if the output of the pressure sensor is within the second pre-determined range.
