Code P2016 2009 Toyota Camry Description

The Intake Manifold Runner Valve (IMRV) system is mounted on the intake manifold and consists of the intake manifold runner valve (IMRV), the IMRV motor and the IMRV position sensor. The IMRV motor opens and closes the IMRV using multiple gears. The valve position sensor detects the opening angle of the IMRV. The IMRV has a groove on its upper portion. When the IMRV is closed, air flows through a groove into the cylinder from the intake manifold, so that a dynamic air flow or ”tumble” air flow is generated in the cylinder. The tumble air flow drastically reduces fuel deposits inside the intake air port and the combustion wall surface inside the cylinder. This improves the combustion efficiency by boosting the air−fuel mixture and air flow turbulence.
