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

The Tumble Control Valve (TCV) position sensor is a non-contact type sensor.

The position sensor measures the opening angle of the TCV. The sensor is reliable and accurate, as it is electrically controlled by Hall-effect elements.

DTC No. DTC Detection Condition Trouble Area
P2014 The TCV 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 TCV position sensor circuit
  • Intake air control valve actuator (for TCV)
  • ECM
P2016 The TCV position sensor output voltage is below 0.2 V for more than 0.5 seconds (short) (1 trip detection logic).
  • Open or short in TCV position sensor circuit
  • Intake air control valve actuator (for TCV)
  • ECM
P2017 The TCV position sensor output voltage is higher than 4.8 V for more than 0.5 seconds (open) (1 trip detection logic).
  • Open or short in TCV position sensor circuit
  • Intake air control valve actuator (for TCV)
  • ECM

HINT: 

When DTC P2014, P2016 or P2017 is output, use the Techstream to confirm the IAC Sensor Voltage (TCV position sensor output voltage). Enter the following menus: Powertrain / Engine / Data List / All Data.

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