EGR Switch-Over Valve: Description and Operation

PURPOSE

The LH control module controls exhaust gas recirculation via the EGR switchover valve (Y27). The switchover valve connects the EGR valve to
vacuum from the throttle valve assembly.

LOCATION

The valve is located in engine compartment on passenger side front corner of vehicle.

OPERATION

When the LH control module energizes the switchover valve, the valve opens and vacuum reaches the EGR valve.
