Keep an accurate eye on engine oil pressure with the Standard Ignition Engine Oil Pressure Switch PS681. This switch threads into the engine's oil pressure port and monitors oil pressure, opening or closing its circuit to operate the vehicle's oil pressure warning light or gauge sender circuit — a replacement for a worn or leaking original.
Diagnose the cause of the symptom first; if a failed oil pressure switch is confirmed as the cause, this unit replaces it and provides the correct signal to the warning light or gauge.
