    How NBo2 Sensor Input Controls Fuel Delivery

    Have recently updated the subject document. Despite the document specifically addressing the $8d AUJP code and calibration, the concepts apply equally to both MAF and other SD masks.

    This document describes how Injector Base Pulse Width (BPW) is calculated, and then how it is corrected in Closed Loop (CL) with NBo2 sensor input. Also addressed is the effect on BPW if o2-related Calibration values are changed. BPW determination in Open Loop (OL) is also addressed.
