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.Associated with low engine fluid pressure. The reason most likely is the lack of oil in the engine, so first of all you need to check the amount of consumable. You should also make sure that the engine fluid pressure sensor is working.


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.
