Fault monitor () for error input (ICPCERR) to closed-loop control () of an engine function, such as a control pressure for a fuel system (). Error input is derived from the desired and actual data values for the function.

A comparison function () compares the integrated data value and a data value ICPCOBDERR defining a fault indication.
