4GR-FSE ENGINE CONTROL SYSTEM: SFI SYSTEM: P2014, P2016, P2017: Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1)
P2017 - Intake Manifold Runner Position Sensor / Switch Circuit High (Bank 1)
DESCRIPTION
The Swirl Control Valve (SCV) position sensor is a non-contact type.
The position sensor measures the opening angle of the SCV. The sensor is reliable and accurate, as it is electrically controlled by Hall elements.
HINT
After confirming DTC P2014, P2016 or P2017, use Techstream to confirm the IAC Sensor Voltage (Swirl control valve position sensor output voltage) by entering the following menus: Powertrain / Engine / Data List / All Data / IAC Sensor Voltage.
MONITOR DESCRIPTION
The ECM's IAC1 terminal voltage increases in correlation with the opening angle of the swirl control valve. When the swirl control valve is fully closed, approximately 0.6 V is applied to the IAC1 terminal. When the swirl control valve is fully open, approximately 3.6 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.

COMPONENT OPERATING RANGE
CONFIRMATION DRIVING PATTERN
1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the Techstream on.
3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure) Reading and Clearing Diagnostic Trouble Codes.
4. Turn the engine switch off and wait for at least 30 seconds.
5. Turn the engine switch on (IG) and turn the Techstream on.
6. Wait 0.5 seconds or more.
7. Enter the following menus: Powertrain / Engine / Trouble Codes.
8. Read the pending DTC.
HINT
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
9. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
10. Input the DTC: P2014, P2016 or P2017.
11. Check the DTC judgment result.
HINT
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows NORMAL, the system is normal.
12. If the test result is INCOMPLETE or N/A and no DTC is output, perform a universal trip and check for permanent DTCs Reading and Clearing Diagnostic Trouble Codes.
HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.
WIRING DIAGRAM
INSPECTION PROCEDURE
HINT
- If other DTCs relating to different systems that have terminal E2 as the ground terminal are output simultaneously, terminal E2 may have an open circuit.
- Read freeze frame data using Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air/fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction Freeze Frame Data.
PROCEDURE
1. PERFORM ACTIVE TEST USING TECHSTREAM (OPERATE SWIRL CONTROL VALVE)
(a) Connect Techstream to the DLC3.
(b) Turn the engine switch on (IG) and turn the Techstream on.
(c) Enter the following menus: Powertrain / Engine / Active Test / Control the SCV Duty Ratio / All Data / IAC Sensor Voltage.
(d) Check the output voltage of IAC Sensor Voltage while changing Control the SCV Duty Ratio from -100 to 100% (or from 100 to -100%) using the Techstream.
Standard:
The voltage output of IAC Sensor Voltage remains between 0.2 to 4.8 V while Control the SCV Duty Ratio is driven from -100 to 100% (or from 100 to -100%).
