What is the p16cf chevy for the malibu code?

If Your Chevy Malibu has returned a P16CF code, You have a problem with Your rocker arm actuator system. Diagnosing the problem alone will generally cost about 1 hour of labor, which is about $50 to $70. The repair itself is going to vary greatly in price, depending on the model year, location, and amount of work that needs to be done. The rocker arm actuator system is responsible for making the ECM change the camshaft lift during engine operation. Each intake valve of the camshaft has three lobes. The two outer ones are designated to high lift while the single inner one is for low lift. The ECM sends a signal to the rocker arm solenoid and the system ultimately controls the flow of the oil to the rocker arm.
