EGR monitored data understanding
EGR valve is causing Motor control system error warning light on my Jtd GT.
I checked and monitored engine data with software and EGR was showing 0,8% up to 100% and all the values in the middle during first 7 minutes of the drive. After that(last 5 minutes of the drive) EGR was showing 0,8% value if the engine was on idle or accelerating hard. Is that normal or not?
What means 0% and what means 100% in my monitored data; or what means closed and what opened position?
When usually come to EGR error, when EGR is sticked closed or opened?
Do I have to change the EGR or just clean it?
Otherwise the car is performing normal.
