Detailed Description

Standard Ignition FLS355 is an engine oil level sensor intended for vehicles that rely on an electronic oil level signal rather than a manual dipstick check alone. The connector design uses a female oval plug with three male blade terminals, which helps ensure proper electrical interface when replacing a failed sensor.
