Cylinder deactivation cylinoid,it will deactivate the cylinder,if no load on it to save fuel,it is controlled by the ecm,the known problems, are bad cylinoid,bad wiring,or false signal from the ecm,try to reset it by removing + cable for a few minute,s,if it returns,then you may need to have it serviced,make sure when you remove cable,don,t have key in the truck.
Thank you for your help, but my solenoid is new, with the scanner I activate or deactivate the solenoids , and they activate correctly so the car is working ok but the check light is on, do you know if there is any wire to the pcm from which I can disable the check light just so it doesn't come on again?.
