Standard Ignition PS-205 Engine Oil Pressure Switch

Engine Oil Pressure Switch for Gauge Applications

Standard Ignition PS-205 is an engine oil pressure switch built for vehicles equipped with an oil pressure gauge. It is engineered for accurate pressure reading, stable electrical connection, and dependable operation in demanding underhood conditions. This PS-205 oil pressure switch is a direct-fit service part for many Chrysler, Dodge, and Plymouth applications from the 1980s and early 1990s.

Key Features

• Male connector gender with a male screw terminal
• Single-terminal design for gauge-equipped oil pressure circuits
• High-temperature polyimide film diaphragm construction
• Built to resist rupture and oil leakage under pressure pulsation
• Laser-etched calibration process for accurate oil pressure reading
• 100% tested with automated leak and activation checks

Detailed Description

Standard Ignition PS-205 is designed for engines that use an oil pressure gauge rather than a warning-light-only sender. The switch uses a calibrated thick-film circuit and a durable diaphragm design to help maintain accurate signal output as engine oil pressure changes. Robust materials and construction support repeated cycling and exposure to harsh engine bay conditions. This part cross-references Anchor 8166 for the same application.

Vehicle coverage includes many Chrysler, Dodge, and Plymouth models, including Fits 1984-1988 Dodge Caravan, Fits 1984-1988 Dodge Daytona, and Fits 1984-1988 Plymouth Voyager. It also applies to Fits 1990 Dodge Dakota, Fits 1987-1988 Dodge Grand Caravan, and Fits 1984-1988 Chrysler LeBaron for oil-pressure-gauge-equipped engines. The PS-205 part number is also listed across multiple interchange references for service matching.

What It Helps Address

• Inaccurate oil pressure gauge readings
• Intermittent gauge movement or signal loss
• Oil pressure switch leakage at the sensor body
• Electrical connection issues at the single-terminal screw connection
• Replacement needs on gauge-equipped Chrysler, Dodge, and Plymouth engines

Installation Notes and Tips

Verify that the vehicle uses an oil pressure gauge before ordering. Match the connector style, terminal type, and engine application to the original part. Clean the mounting area before installation and inspect the harness connection for corrosion or damaged terminals. Confirm the replacement is correct for the specific model year and engine configuration listed for PS-205.

Quality Assurance

Standard Ignition states that each unit is tested with automated equipment for activation and leak checking, then stressed to confirm specification compliance. The PS-205 is built with high-grade materials and a durable diaphragm design to meet service demands in everyday repair use.
