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) [04/2013 - 08/2015]: Description

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

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-effect elements.

HINT: 

When DTC P2014, P2016 or P2017 is output, use the Techstream to confirm the IAC Sensor Voltage (swirl control valve position sensor output voltage). Enter the following menus: Powertrain / Engine and ECT / Data List / Gas Intake Control / IAC Sensor Voltage.

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