Standard Ignition PS-284 Engine Oil Pressure Switch

Engine Oil Pressure Switch for Accurate Gauge Readings

Standard Ignition PS-284 is an engine oil pressure switch built for vehicles that rely on an oil pressure gauge signal. It is engineered with a female plug-in connector, 2 male bullet terminals, and a black, silver finish for straightforward service replacement.

Fits 1996-1997 Jeep Cherokee, gauge-equipped applications and 1997 Dodge Dakota, 1996-1997 Jeep Grand Cherokee, 1997 Jeep TJ, and 1997 Jeep Wrangler with engines that have oil pressure gauges.

Key Features

• Standard Ignition PS-284 engine oil pressure switch
• Laser-etched calibration process for accurate oil pressure reading
• Polyimide film diaphragm construction for cycle durability
• Resists rupture and oil leakage under demanding conditions
• Handles rapid pressure pulsations without component damage
• Female plug-in connector with 2 male bullet terminals
• Black and silver housing with aluminum and plastic finish

Detailed Description

The PS-284 is designed for oil pressure gauge applications where stable signal output matters. Standard Ignition uses a laser etching system to calibrate the printed circuit, helping the switch report actual engine oil pressure with precision. The diaphragm design uses high-temperature polyimide film to support durability in hot engine environments and to reduce the risk of leakage or rupture.

This part cross-references Four Seasons 57309 for the same application. Standard Ignition PS-284 is a direct-fit service part for select Jeep and Dodge applications, including 1997 Dodge Dakota and 1997 Jeep Wrangler oil pressure gauge setups.

What It Helps Address

• Inaccurate or erratic oil pressure gauge readings
• Oil pressure warning or gauge signal faults
• Switch leakage at the engine sender location
• Signal instability during rapid pressure changes
• Wear-related failure in high-heat engine service

Installation Notes and Tips

Verify the connector style and terminal layout before installation. This PS-284 uses a female plug-in connector and 2 male bullet terminals, so the harness must match the switch design. Confirm the vehicle is equipped with an oil pressure gauge and match the application to the exact year, make, and model listed for your Jeep Cherokee, Jeep Grand Cherokee, Jeep TJ, Jeep Wrangler, or Dodge Dakota.

Quality Assurance

Standard Ignition tests each unit with automated equipment that activates the switch, checks for leaks, and verifies performance under demanding operating conditions. The robust construction and high-grade materials are selected to meet the requirements of professional engine service.
