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

HINT:

This IMRV position sensor is non-contact type.

The IMRV position sensor is mounted on the valve shaft axis (See DTC P2004 INTAKE MANIFOLD RUNNER CONTROL STUCK OPEN (BANK 1); DTC P2006 INTAKE MANIFOLD RUNNER CONTROL STUCK CLOSED (BANK 1)  ) 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 (See DTC P2004 INTAKE MANIFOLD RUNNER CONTROL STUCK OPEN (BANK 1); DTC P2006 INTAKE MANIFOLD RUNNER CONTROL STUCK CLOSED (BANK 1)  ), and P2009 and P2010 (See DTC P2009 INTAKE MANIFOLD RUNNER CONTROL CIRCUIT LOW (BANK 1); DTC P2010 INTAKE MANIFOLD RUNNER CONTROL CIRCUIT HIGH (BANK 1)  ).
