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): Description

WARNING: This page is about a different variant/trim than selected.

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.

DTC No. DTC Detection Condition Trouble Area
P2014 The tumble control valve position sensor output voltage flutters up and down beyond the normal operating range (below 0.2 V or higher than 4.8 V) for more than 0.5 seconds (open or short) (1 trip detection logic).
  • Open or short in tumble control valve position sensor circuit
  • Tumble control valve position sensor
  • ECM
P2016 The tumble control valve position sensor output voltage is below 0.2 V for more than 0.5 seconds (short) (1 trip detection logic).
P2017 The tumble control valve position sensor output voltage is higher than 4.8 V for more than 0.5 seconds (open) (1 trip detection logic).

HINT: 

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

IAC Sensor Voltage Malfunction
0.2 V or less
  • IAC1 circuit shorted
  • VCIA circuit open
4.8 V or higher
  • VCIA and IAC1 circuit shorted
  • IAC1 circuit open
  • EIA1 circuit open
