METHODS AND SYSTEM FOR DETERMINING OFFSET OF MANIFOLD PRESSURE SENSOR Russian patent published in 2018 - IPC F02D41/22 

FIELD: engines.

SUBSTANCE: invention relates to internal combustion engines with a manifold pressure sensor. Disclosed is a method for determining an offset of a manifold pressure sensor, which includes indicating degradation of the manifold pressure sensor based on a sensor offset, the sensor offset based on a manifold pressure measured at a first throttle angle, a barometric pressure at a second throttle angle, a reference manifold pressure at the first throttle angle and reference barometric pressure. Further, the method may include adjusting an output of the manifold pressure sensor by the determined sensor offset.

EFFECT: technical result is to indicate degradation of the manifold pressure sensor.
