4.16.1 Description

This monitor runs continuously. The voltage from the sensor is compared with failure thresholds defined in the software. If the sensor voltage is less than the minimum threshold, a timer will be started. If this timer exceeds a threshold, a failure flag is set and a DTC is stored. If the sensor voltage is greater than the maximum threshold, a timer will be started. If this timer exceeds a threshold, a failure flag is set and a DTC is stored.
