The Malibu / Chevrolet Oil Level Sensor (556291) is a critical engine protection component used on GM-based marine engines. This sensor continuously monitors the engine oil level and communicates with the ECM to help prevent low-oil operation that can lead to serious engine damage.
Built with marine-grade materials and featuring a reliable 2-pin electrical connector, this sensor is designed for dependable performance in harsh marine environments. If your system is showing oil level warnings or erratic readings, replacing the sensor can restore proper monitoring and peace of mind on the water.
