Welcome to JustAnswer!!! My name is***** will be helping you with your question today...
This test will fail if the EGR Temperature is greater than a calibrated threshold for a calibrated period of time when the EGR Bypass Valve is closed. This monitor protects the system from a failed EGR Cooler. It could be a bad temp sensor, bad EGR cooler, low on coolant, EGR codes, etc..
To find the issue you will need to follow the diagnostic chart I have attached..
