An apparatus includes a sensor module, an offset diagnostic module, and a notification module. The sensor module is in operative communication with a cylinder pressure sensor and structured to acquire cylinder pressure data from the cylinder pressure sensor indicative of an actual in-cylinder pressure of a cylinder of an engine. The offset diagnostic module is structured to interpret the cylinder pressure data to determine an offset of the cylinder pressure sensor based on a reference in-cylinder pressure and the actual in-cylinder pressure. The notification module is structured to provide an offset error notification responsive to the offset being greater than a threshold offset.

Diagnosing cylinder pressure sensor gain and offset

Systems and apparatuses include a passive device coupled to a mounting boss arranged on a vehicle system, and a sensor structured to engage the mounting boss. The sensor includes a probe structured to sense a characteristic of the vehicle system, and a reader structured to send a query signal to the passive device and receive location data from the passive device associated with the mounting boss.

Systems and methods for identifying sensor location

Systems and methods for managing aftertreatment systems that include passive NOadsorption devices and SCR catalyst elements are disclosed. Temperature generation devices upstream of the passive NOadsorption devices facilitate control of the aftertreatment systems to improve fuel economy and NOconversion efficiency.
