ACDelco Gold D8055 (19112977) Engine Oil Level Sensor is a premium aftermarket replacement that monitors engine oil height and reports low-oil conditions to your vehicle’s dashboard.

How does this sensor detect low oil and pass alerts to the dash?

The sensor measures the oil column in the oil pan and sends an electrical signal to the vehicle’s body control module or information center when levels fall below the calibrated threshold. This allows the dash to display a low-oil message or warning lamp so drivers can take action before oil pressure or lubrication becomes a concern.
