Medium and Heavy Trucks
Have Truck Repair Questions? Ask an Expert
Hi my name is***** will be glad to help. What is the engine model and serial number and year truck? What are the fault codes you are getting?
Hi Buddy, There will be a fault code number logged in the ECM that will tell us the problem area to look into for the EGR circuit whether it be the valve itself or potential harness problem etc. Do you have access to a scan tool to pull your codes or do you have the display panel in your dash that will display your faults? If not try Cruise off, Key on, hold set resume switch until the check engine light flashes the three digit code with short pauses in between each digit and a longer pause between codes. Some trucks have a diagnostic switch instead. LEt me know
Hi Buddy, Did you get this resolved?
