Circuit/System Description

WARNING: This page is about a different variant/trim than selected.

In order to compensate for variations in the fuel system, the fuel mass observer function uses feedback from the Heated Oxygen Sensor (HO2S) to calculate the correction quantity. A DTC will set when the correction quantity reaches the emission OBD limit.
