EGR Valve: Testing and Inspection
On-Vehicle Inspection
1. Crank the engine and listen for initialization noise (clicks) of the EGR valve by using a screwdriver or a soundscope.
-
If the initialization noise is not heard, inspect for continuity of the wiring harness between the EGR valve and the PCM and inspect the EGR
valve.
NOTE: EGR valve initialization is closing action of the valve observed before and after the engine is started and when the engine is stopped.
