DTC P2017 INTAKE MANIFOLD RUNNER POSITION SENSOR/SWITCH CIRCUIT HIGH (BANK 1)HINT:
- These DTCs have been added to meet the requirement for Partial Zero Emission Vehicle (PZEV).
- This is the repair procedure for the Intake Manifold Runner Valve (IMRV) position sensor.

Component Operating Range:
HINT: This IMRV position sensor is non-contact type.
The IMRV position sensor is mounted on the valve shaft axis and is used to measure the opening angle of the IMRV. Since this sensor is electronically controlled with hall elements, accurate control and reliability can be obtained.
Voltage of approximately 0.6 V is applied to terminal IACA of the ECM when the IMRV is fully closed. The voltage applied to terminal IACA increases in proportion to the IMRV opening angle, approximately 3.6 V is applied to the terminal when it is fully opened.
The ECM detects a malfunction in the IMRV position sensor when its voltage output deviates from the standard range. When a malfunction is detected, the ECM fully opens the IMRV using the IMRV motor until the IMRV position sensor returns to normal.
The related DTCs are P2004 and P2006, and P2009 and P2010.
HINT: After confirming DTC P2014, P2016 or P2017, use the hand held tester or the OBD II scan tool to confirm the IACV POSITION (IMRV position sensor output voltage) from DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL .

INSPECTION PROCEDURE
HINT:
- If different DTCs that are related to a different system are output simultaneously while terminal E2 is used as a ground terminal, terminal E2 may be open.
- Read freeze frame data using hand-held tester or the OBD II scan tool. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction.
