Abstract
Methods and systems are provided for improving engine oil level sensing while a vehicle is moving. The output of a hot wire sensor partially immersed in an engine oil well is sampled during selected vehicle moving conditions when lateral and longitudinal acceleration is limited and the vehicle is driving in a straight line. A transfer function is used to correlate a rate of change in sensor output, sampled during the selected vehicle operating conditions, with engine oil level.
