Observe all safety precautions: SAFETY PRECAUTIONS

View clean working conditions: CLEAN WORKING CONDITIONS

Use only gold-plated terminals when servicing any component with gold-plated electrical harness connector terminals.

For wiring diagrams, component locations, and connector views, Refer to the applicable wiring diagram.

NOTE:

The Exhaust Gas Recirculation Motor 2 and EGR Potentiometer 2 both refer to the same component (V339). Name changes occur in wiring diagrams, parts listings etc. The EGR potentiometer G466 is part of the V339 motor assembly and is serviced as one component.

Special tools and workshop equipment required

Multimeter
Electrical connector test lead set

Test conditions
