CM871 EGR Valve. - Spreaduraxles - 09-15-2022
What sensor controls the EGR valve on a CM871 ISX15.
RE: CM871 EGR Valve. - windowrattler - 09-15-2022
There is no specific sensor that controls the valve. The ecm uses a bunch of different data to determine how much to open the valve. I think what you might be after is the egr temp sensor plug which disables egr opening when unplugged.
