DTC Code	DTC Name
P2014	Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2016	Intake Manifold Runner Position Sensor / Switch Circuit Low (Bank 1)
P2017	Intake Manifold Runner Position Sensor / Switch Circuit High (Bank 1)

DESCRIPTION

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).

Tech Tips

After confirming DTC P2014, P2016 or P2017, use the GTS 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

MONITOR DESCRIPTION

The ECM IAC1 terminal voltage increases in correlation with the opening angle of the tumble control valve. When the tumble control valve is fully closed, approximately 0.94 V is applied to the IAC1 terminal. When the tumble control valve is fully open, approximately 3.39 V is applied to the IAC1 terminal.

When the output voltage of the IAC1 terminal deviates from the standard range, the ECM determines that a malfunction has occurred in the position sensor and stores a DTC.

CONFIRMATION DRIVING PATTERN

Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) Click here.
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and turn the GTS on.
Wait 0.5 seconds or more.
Enter the following menus: Powertrain / Engine / Trouble Codes.
Read the pending DTCs.
Tech Tips
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P2014, P2016 or P2017.

Check the DTC judgment result.

GTS Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions
N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

Tech Tips

If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE

PERFORM ACTIVE TEST USING GTS (OPERATE TUMBLE CONTROL VALVE)

Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Enter the following menus: Powertrain / Engine / Active Test / Control the IAC Duty Ratio / All Data / IAC Sensor Voltage.

Check the output voltage of IAC Sensor Voltage while changing Control the IAC Duty Ratio from -100 to 100% (or from 100 to -100%) using the GTS.

OK

The voltage output 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%).
