Cause :

If this error lights up and service icons appear on the dashboard, then to remove it, you need to check the operation of the electric motor of the valve lift adjustment mechanism. To reset the code, you must determine the cause of the open loop.Malfunction of the variable valve lift system. The control unit notes that the position of the natural opening of the throttle is not reached. The problem often comes out after cleaning the latter. The engine stalls immediately at the factory or at idle.


Don't forget ! When a fault code pops up, CAT's Uptime Center is automatically notified via an cellular link, and it alerts the truck's owner by prearranged methods, usually email or phone calls.
