The Valvetronic System is a variable valve lift system that, in combination with variable valve timing, allows infinite adjustment of the intake valve timing and duration. The system helps improve fuel economy and emissions and negates the need for a throttle body in regular use. The Eccentric Shaft Position Sensor is used as feedback for the Valvetronic Eccentric Shaft. The Valvetronic Eccentric Shaft is actuated by Valvetronic Motor and in return controls the variable intake valve lift. The Eccentric Shaft Sensor is mounted to the cylinder head beneath the valve cover. The Diagnostic Trouble Code (DTC) will be set if the Valvetronic Eccentric Shaft Sensor is not to factory specifications.
