WebbUnlike the transistor, the SCR can not be biased to stay within some active region along a load line between its blocking and saturation states. The magnitude and duration of the gate “turn-on” pulse has little effect on the operation of the device since conduction is controlled internally. WebbIf no issues are found with the sensor readings from the NOx Conversion review, the sensors are not the source of the conditions causing the codes to log. Further diagnostic steps of other components will need to be performed to determine the cause of the faults. 4. If this solution is being reviewed for P20EE, P207F, P225E or P103C, the DEF Dosing
