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) [12/2013 - 11/2016]: Procedure

WARNING: This page is about a different variant/trim than selected.
  1. PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE IAC DUTY RATIO) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON and turn the Techstream on.
    3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the IAC Duty Ratio / Gas Intake Control / IAC Sensor Voltage.

      Powertrain > Engine > Active Test 

      Active Test Display
      Control the IAC Duty Ratio
      Data List Display
      IAC Sensor Voltage
    4. Check the value of IAC Sensor Voltage while changing Control the IAC Duty Ratio from -100 to 100% (or from 100 to -100%) using the Techstream.

      OK

      The value of IAC Sensor Voltage remains between 0.2 and 4.8 V while Control the IAC Duty Ratio is changed from -100 to 100% (or from 100 to -100%).

      HINT: 

      Control the IAC Duty Ratio Operation IAC Sensor Voltage (Normal) Suspected Trouble Area
      • IAC1 circuit shorted
      • VCIA circuit open
      • VCIA and IAC1 circuits shorted
      • IAC1 circuit open
      • EIA1 circuit open
      		 Sensor malfunction
      -100% 0.2 to 1.4 V Remains below 0.2 V Remains higher than 4.8 V Other than the voltage in the 2 columns on the left
      100% 3.2 to 4.8 V Remains below 0.2 V Remains higher than 4.8 V
