Air Injection Control Valve: Description and Operation
PURPOSE
The right LH control module (N3/3) controls air injection via the air injection pump switchover valve (Y32). The switchover valve connects the
air injection shut-off valve (126) to vacuum from the intake manifold.
OPERATION
When the LH control module energizes the switchover valve, the valve opens and vacuum reaches the air injection shut-off valve.
