Standard Ignition PS-203 Engine Oil Pressure Switch

Engine Oil Pressure Switch for Gauge Applications

Standard Ignition PS-203 is an engine oil pressure switch built for vehicles that use an oil pressure gauge. It is engineered with a male connector, male terminal, and stud-style terminal connection for straightforward electrical interface in the correct application.

• Engine oil pressure switch for gauge-equipped applications
• Male connector and male terminal design
• Single stud terminal configuration
• Laser-etched calibration for accurate oil pressure reading
• Polyimide film diaphragm for cycle durability and leak resistance
• Built to handle rapid pressure pulsations without component damage

Fitment and Application Details

Compatible with 1982-1983 Chrysler LeBaron, 1983 Dodge 600, 1982-1983 Dodge Aries, 1983 Dodge Dart, 1982-1983 Plymouth Reliant, 1983 Plymouth Turismo, 1982 Dodge Magnum, 1982 Plymouth TC3, and 1974 Jeep J20. Fitment notes include gauge and screw-on type applications, with the 1974 Jeep J20 listed for light-duty use. Standard Ignition PS-203 is a direct service part for these oil pressure gauge and warning-light configurations.

This part cross-references Standard Motor Products (e.g., PS146, PS151) for the same application.

What This Part Helps Address

• Inaccurate or unstable oil pressure gauge readings
• Oil pressure warning light concerns tied to a failed switch
• Electrical signal issues at the oil pressure sender circuit
• Leaks caused by worn internal switch components
• Switch failure from repeated pressure pulsation and heat exposure

Installation Notes and Tips

Verify the connector style, terminal type, and thread/screw-on configuration before installation. This PS-203 oil pressure switch is listed for specific Chrysler, Dodge, Plymouth, and Jeep applications, including engines with oil pressure gauges. Confirm the vehicle’s original switch style and gauge or light setup to match the correct application.

Quality Assurance

Standard Ignition uses laser-etched circuit calibration, high-temperature polyimide film diaphragms, and automated 100% testing for activation, leak checking, and stress verification. These manufacturing controls are used to support consistent performance in demanding service conditions.
