Fig 1: Locating Variable Intake Manifold Switchover Valve

The variable intake manifold switchover valve is located at the front to the left of the variable intake manifold.

Task

The variable intake manifold switchover valve discharges the variable intake manifold vacuum capsule for the purpose of intake manifold switchover with vacuum pressure and then ventilates the variable intake manifold vacuum capsule.

Design

The variable intake manifold switchover valve is an electromagnetic switchover valve in plastic housing with a coil resistance of around 25Ω.

A valve plated operated by a coil armature switches between ambient pressure and the vacuum memory.

Function

Fig 2: Identifying Variable Intake Manifold Function

N3/10 The variable intake manifold switchover valve is actuated on the earth side by the ME control unit through its own output stage. Supply voltage is provided by "circuit 87 M2e".
