If the oil level sensor on a 1993 Toyota Previa is illuminated, it may indicate that the engine oil level is low or that there is a problem with the sensor itself. It's important to check the oil level and top it off if necessary. Additionally, a malfunctioning sensor could be due to a faulty connection or a defective sensor. If the oil level is adequate and the light remains on, further diagnosis may be needed to address the sensor issue.
