Standard Ignition PS-301 Engine Oil Pressure Switch

Engine Oil Pressure Switch for Accurate Pressure Readings

Standard Ignition PS-301 is an engine oil pressure switch built for vehicles that use an oil pressure gauge. It is engineered for accurate pressure signal reading, stable operation under rapid pressure changes, and dependable sealing in demanding engine conditions.

Key Features

• Female connector with male pins for a direct electrical connection
• 2-terminal design for oil pressure gauge applications
• High-temperature polyimide film diaphragm for cycle durability
• Built to resist rupture and oil leakage
• Calibrated with laser-etched thick film printed circuits for precise pressure reading
• 100% tested for activation, leak checking, and specification compliance

Detailed Description

This Standard Ignition PS-301 engine oil pressure switch is made for accurate oil pressure monitoring in the engine. The internal circuit calibration process and durable diaphragm construction help the switch respond consistently to changing oil pressure, including rapid pulsations. It is a practical replacement for service work on 2001-2003 Oldsmobile Aurora models equipped with oil pressure gauges, and it supports reliable gauge operation in the vehicle’s engine management system.

This part cross-references AC Delco (e.g., 1S6773, 53-33704) for the same application.

What It Helps Fix

• Inaccurate or erratic oil pressure gauge readings
• Oil pressure warning or gauge signal issues
• Electrical connection problems at the pressure switch
• Oil leakage at the switch body
• Switch failure caused by heat, vibration, or pressure pulsation

Installation Notes and Tips

Fits 2001-2003 Oldsmobile Aurora, N/A, with engines that have oil pressure gauges. Verify the connector style, terminal layout, and thread match before installation. Inspect the harness connector for corrosion or looseness, and confirm the oil system is at the correct level before replacing the switch. Standard Ignition PS-301 should be installed on the correct engine port for accurate gauge operation.

Quality Assurance

Standard Ignition manufactures this switch with automated testing that checks activation, leak integrity, and specification compliance. The design uses high-grade materials and construction methods intended to meet the demands of professional engine service.
