Code P0662 Hyundai Description

Intake manifold turning valve is used to increase torque at lower rpm and increase horsepower at higher rpm. Delta 2.7t engine has two intakes runners for each cylinder. The primary intake runner is a long, thin tube in which the intake air passes through. This allows a strong stream of air to blast into the cylinder, helping low-end torque. The secondary intake runner is a short, fat tube. This allows a large volume of air to be sucked into the engine, increasing high-end horsepower. At lower rpm range, the engine does not provide enough suction into the cylinders, starving the engine of needed oxygen. The skinny tube helps blast the air into the cylinder for more oxygen. At higher rpm, the engine has plenty of suction but the intake runner is too small to provide the oxygen it needs. The short, fat tube allows plenty of oxygen to be sucked in. The Engine Control Module (ECM) controls this function utilizing an intake manifold tuning valve, thereby directing intake air through a longer path for low rpm range or a shorter path for high rpm range.
