Your oil pressure switch is designed to detect extremes in the oil pressure level of your vehicle which results in an oil light appearing in the dash. If this switch breaks; undetected high or low oil pressure can result in internal engine damage and/or gasket leakage. Avoid that potentially expensive issue by replacing it with this factory replacement switch from Omix-ADA that offers a direct fit and OE style accompanied with a limited 5 year warranty.
