Standard Ignition PS-315 Engine Oil Pressure Switch

Engine Oil Pressure Switch for Jeep Applications

The Standard Ignition PS-315 engine oil pressure switch is built for vehicles that use an oil pressure gauge, including select Jeep Grand Wagoneer, Cherokee, Comanche, Wrangler, J10, J20, and Wagoneer applications. It uses a screw-in connector style with a single male blade terminal for a direct service replacement on the listed vehicles.

Key Features

• Engine oil pressure switch for gauge-equipped Jeep applications
• Screw-in connector type with male connector and male blade terminal
• Single-terminal design for straightforward electrical connection
• Black, silver, aluminum, and plastic construction details
• Built to handle rapid pressure pulsations without component damage
• Laser-etched calibration process for accurate oil pressure reading
• Polyimide film diaphragm construction for cycle durability and leak resistance

Detailed Description

Standard Ignition PS-315 is an engine oil pressure switch engineered for accurate pressure signal delivery in gauge-equipped Jeep engines. The design uses high-temperature polyimide film diaphragms and a robust housing to resist rupture and oil leakage under demanding operating conditions. The switch is also tested with automated equipment that checks activation, leak integrity, and specification compliance before release. This makes the PS-315 a practical replacement choice for Jeep Grand Wagoneer, Cherokee, Comanche, Wrangler, J10, J20, and Wagoneer models listed below. This part cross-references 1S6645 and PS232 for the same application.

What It Helps Address

• Inaccurate or erratic oil pressure gauge readings
• Oil pressure warning or gauge signal loss
• Electrical connection issues at the switch terminal
• Leakage at the oil pressure switch body
• Switch failure from repeated pressure pulsation exposure

Installation Notes and Tips

Verify the vehicle uses an oil pressure gauge before ordering. Confirm the connector style, terminal type, and engine application match the existing part. The PS-315 uses a screw-in design with one male blade terminal, so the harness connection should be inspected for fit and corrosion before installation. For Jeep fitment, this part fits 1993 Jeep Grand Wagoneer, 1991 Jeep Grand Wagoneer, 1991 Jeep Cherokee, 1991 Jeep Comanche, 1984-1990 Jeep Cherokee, 1987-1990 Jeep Wrangler, 1988 Jeep J10, 1986 Jeep J10, 1988 Jeep J20, 1987 Jeep J10, 1987 Jeep J20, 1987 Jeep Wagoneer, 1984 Jeep Wagoneer, and 1986 Jeep Wagoneer.

Quality Assurance

Standard Ignition uses laser calibration for accurate pressure reading and automated end-of-line testing to verify activation and leak resistance. The PS-315 is built with durable materials to meet the demands of professional service use.
