U262A Code Symptoms :

There are currently two main types of cylinder deactivation used today, depending on the type of engine. U262A code for the pushrod design which uses solenoids to alter the oil pressure delivered to the lifters. In their collapsed state, the lifters are unable to elevate their companion pushrods under the valve rocker arms, resulting in valves that cannot be actuated and remain closed.
