EGR actuator testing - Makmak - 12-06-2018
Has anyone ever tested or know how to test the Egr actuator for isx871?
Got Code 1893. EGR control circut abnormal update rate.
With key on there is no actuator movement whatsoever. I checked plug voltages at egr and did not get 5v reference or even close, this is what I did get....12.32v...2.65v...3.8v...2.49v
I'm thinking there is not suppose to be a 5v reference like other sensors ? Does anyone have the ecm wiring circuit diagram to post here?
Thanks
