1. A system for controlling an engine having a turbocharger comprising:
an idle determination module determining an engine speed is at idle;
a boost pressure sensor disposed downstream of the turbocharger generating a boost pressure signal when the engine speed is at idle;
a barometric pressure sensor disposed before the turbocharger generating a barometric pressure signal when the engine speed is at idle; and
a controller coupled to the boost pressure sensor and the barometric pressure sensor, said controller programmed to determine an offset between the boost pressure signal and the barometric pressure signal, to compare the offset to a tolerance range, and when the offset is outside the tolerance range, to display an indicator and operate the engine in a limp home mode.
