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.
