S43 Oil level check switch





S43 Oil level check switch
Arrow: Connector

Location
The oil level check switch is in the oil pan; the outer connector is located on the oil pan.

Task
To recognize reaching a minimum oil level in the oil pan.

Design
In the oil pan there is a dry-reed contact mounted in the float chamber and a float with ring magnet. A short line leads to the connector on the side on the oil pan.

Function
When the oil level is adequate the contact to engine ground is closed. If the switch opens due to oil starvation then this is recognized by the ME-SFI [ME] control unit and a message sent over the CAN to the instrument cluster.
