Intake Connection Assembly Overview

Intake Connection Assembly Overview

• When engine is switched off, the intake connection is closed for approximately 3 seconds and then opens again. This reduces the stop jolt.

• The components illustrated correspond to cylinder bank 1. They are a mirror image of the components for cylinder bank 2.

14 Intake connection with intake flap motor

Cylinder bank 1:

• Intake flap motor 1 (V157).

Cylinder bank 2:

• Intake flap motor 2 (V275).

15 Exhaust Gas Recirculation (EGR) vacuum regulator solenoid valve with EGR potentiometer

Cylinder bank 1:

• EGR vacuum regulator solenoid valve (N18) with EGR potentiometer (G212)

Cylinder bank 2:

• EGR valve 2 (N213) with EGR position sensor (G466)

If the EGR valve with EGR potentiometer is replaced, then do the following:

- Switch ignition on and off.

- Then wait for one minute for the control module after run.

- Start engine and let run at idle for at least 1 minute.

- Then, check the Diagnostic Trouble Code (DTC) memory of the Engine Control Module (ECM). Refer to --> [ Engine Control Module, DTC Memory Checking and Erasing ] Component Tests and General Diagnostics.

If a fault is stored in DTC memory:

- Repeat work procedure.
