Standard Ignition PS-223 Engine Oil Pressure Switch

Engine Oil Pressure Switch for Accurate Pressure Signal

Standard Ignition PS-223 is an engine oil pressure switch built for vehicles that rely on a precise oil pressure signal for the gauge or warning light circuit. It uses a 3-terminal blade design with a female connector and male terminals for straightforward electrical connection in the correct application.

Key Features

• Engine oil pressure switch for pressure monitoring and indicator-light circuits
• 3-terminal blade configuration
• Female connector with male terminals
• High-temperature polyimide film diaphragm construction
• Built to handle rapid pressure pulsations without component damage
• 100% tested with automated leak and activation checks

Detailed Description

The Standard Ignition PS-223 is engineered for accurate oil pressure reading in the engine’s pressure monitoring system. Laser-etched calibration of the thick film printed circuits supports consistent signal output, while the diaphragm material is selected for durability and resistance to rupture and oil leakage. This makes the PS-223 a practical replacement for vehicles that need a dependable engine oil pressure switch, including select Pontiac Sunbird, Pontiac LeMans, Buick Skyhawk, Oldsmobile Firenza, and Pontiac Grand Am applications.

This part cross-references Bosch 8153 for the same application.

What This Part Helps Address

• Oil pressure warning light staying on or not responding correctly
• Inaccurate oil pressure signal to the gauge or indicator circuit
• Electrical issues at the switch connection point
• Leakage at the oil pressure switch body
• Intermittent operation caused by pressure pulsation or switch wear

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle application before installation. This PS-223 uses a female connector, male blade terminals, and a 3-terminal layout, so the replacement must match the original electrical configuration. Confirm the engine oil pressure switch location and inspect the harness connector for corrosion or looseness before connecting the new part.

Quality Assurance

Standard Ignition states that each unit is tested with automated equipment for activation, leak checking, and specification compliance. The design uses high-grade materials and is built to meet the demands of professional service use.
