Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1) (P2014,P2016,P2017)
DESCRIPTION
The tumble control valve position sensor is a non-contact type sensor.
The position sensor measures the opening angle of the tumble control valve. The
sensor is reliable and accurate, as it is electrically controlled by Hall elements.
