An oil drain plug and wireless oil level sensor assembly is provided including an oil drain plug having a shaft and a head, the shaft having external threads and an axial passage extending axially therein in communication with at least one radial passage extending through the shaft from the axial passage to an exterior of the shaft. An oil level sensor includes a housing having an annular mounting portion defining an aperture extending there through for receiving the shaft of the oil drain plug. A pressure transducer is in fluid communication with the aperture and connected to a circuit and a battery disposed within the housing that provide wireless signals representative of the oil level.

Adaptation of a wireless oil level sensor to an oil pan drain plug

A control methodology for a wireless oil level sensor includes mounting a wireless oil pressure sensor to the oil plug of an engine. The oil pressure sensor detects a pressure which is used to determine a volume or level of oil in the oil pan. The oil level sensor can include an accelerometer sensor that can be excited by the vibration caused by the starting of the engine to 'wake up' the sensor. The sensor can take an initial pressure reading at start up and associate the pressure reading with an oil level that can then be transmitted to a vehicle control unit. The sensor can remain idle until the accelerometer sensor no longer detects engine vibrations. The sensor is activated to take pressure readings at predetermined time intervals and to transmit an associated oil level to the vehicle central processor unit until a predetermined time period has expired.
