Theory of Operation
TheEGRvalvehasapositionsensorandthe EGR position rationality is designed to make sure that the valve
moves freely within its operating range. Closed valve position referencecheck verifies that the valve is within its
allowable upper and lower limits. The EGR position rationality test looksfor a sustained error relative to commanded
valve position.
When Monitored:
Engine running.
Set Condition:
The EGR flow or valve movement is not what is expected. A rationality error has been detected for the EGR
Open Position Performance. Two trip fault.
