DTC P2014: Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1); DTC P2016: Intake Manifold Runner Position Sensor / Switch Circuit Low (Bank 1); DTC P2017: Intake Manifold Runner Position Sensor / Switch Circuit High (Bank 1) [08/2013 - ]: Description

The Swirl Control Valve (SCV) position sensor is a non-contact type.

The position sensor measures the opening angle of the swirl control valve. The sensor is reliable and accurate, as it is electrically controlled by Hall elements.

HINT: 

After confirming DTC P2014, P2016 or P2017, use the Techstream to confirm the IAC Sensor Voltage (swirl control valve position sensor output voltage) by entering the following menus: Powertrain / Engine / Data List / IAC Sensor Voltage.

IAC Sensor Voltage Malfunction
0.2 V or less
  • IAC1 circuit shorted
  • VC circuit open
4.8 V or more
  • VC and IAC1 circuit shorted
  • IAC1 circuit open
  • E2 circuit open
