Circuit Description

WARNING: This page is about a different car, the 2003 Toyota Camry. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: These DTCs have been added to meet the requirement for Partial Zero Emission Vehicle (PZEV). See PARTIAL ZERO EMISSION VEHICLE  under DESCRIPTION.

The intake manifold runner valve (IMRV) motor is driven by the engine control module (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. See Fig 1. The related DTCs are:

After repair is completed, you can use the hand-held tester to confirm the IACV POSITION (IMRV position sensor output voltage) while performing the IACV MOTOR (IMRV motor) of the ACTIVE TEST. See IDENTIFYING ACTIVE TEST NORMAL CONDITION  table.
