Circuit Description

The Intake Manifold Runner Valve (IMRV) motor is driven by the ECM. The IMRV motor opens and closes the IMRV.

When the current of the IMRV motor deviates from the standard range, the ECM determines that there is a malfunction.

The related DTCs are P2004 and P2006 and P2014 , P2016 and P2017 .

NOTE: Do not disassemble the IMRV and the IMRV motor.
