Ruizure Engine Oil Pressure Sensor PS291 for Dodge & Jeep 1998–2003 — 2‑Pin Direct Fit, Durable Construction

Ruizure's Engine Oil Pressure Sensor Sender Switch PS291 is a direct-fit replacement that monitors oil pressure for select Dodge and Jeep models from 1998–2003, restoring accurate gauge or warning-light readings.

If your oil pressure warning light is illuminating erratically or the gauge shows incorrect values, a faulty pressure sensor is a common cause. This Ruizure PS291 sensor is made as a compatible aftermarket replacement for many Dodge Ram, Jeep, and Dodge van models listed for 1998–2003. It features durable construction, a 2-pin electrical connector, and a list of interchange part numbers to help confirm fitment before purchase.

How do I know this sensor fits my vehicle?

Confirming fit requires checking both the model year and the oil pressure system type on your vehicle—some units use a warning light, others a pressure gauge, and connector pin counts vary. Ruizure PS291 is explicitly a 2-pin connector sensor and will not fit 3-pin systems.

• Compatible models include Dodge Ram 1500/2500/3500 (selected years), Jeep Grand Cherokee and Wrangler (1998), Dodge Durango/Dakota (1998–2002), and some Dodge vans.
• Compare your old sensor’s connector count (2-pin only) before ordering.
• Use interchange part numbers (PS291, 56031005, 5003675AA, etc.) to cross-check compatibility.

What symptoms indicate the oil pressure sensor is failing?

A failing sensor typically causes incorrect gauge readings or an illuminated oil pressure warning light. You may see fluctuating readings, false low-pressure alerts, or no warning when pressure is actually low.

• Oil pressure warning light that turns on or off unpredictably.
• Abnormal or erratic oil pressure gauge behavior.
• Noise from the engine that might result from inadequate oil pressure (indirect symptom).

How difficult is installation and what tools are required?

Installation is generally straightforward for someone comfortable with basic automotive maintenance: locate the old sender, disconnect the 2-pin connector, remove the sensor, and install the replacement. Proper torque on the threaded port and a secure electrical connection are important to avoid leaks and false readings.

• Basic hand tools: wrench or socket set sized for the sensor thread.
• Shop rags to catch minor oil drips and thread sealant or tape if recommended by a mechanic.
• Verify electrical connection is clean and secure after installation.

What quality assurances and part cross-references are included?

Ruizure builds this sensor from durable materials designed for under-hood conditions and backs it with a 2-year warranty. A comprehensive interchange list helps confirm the PS291 matches OEM or aftermarket part numbers you may already have.

• 2-year Ruizure warranty for parts confidence and post-sale support.
• Interchange numbers provided (PS291, PS-291, 56031005, 5003675AA, 88924467, and others).
• Manufactured to withstand typical engine bay temperatures and vibration.

Who is this for: The Ruizure PS291 oil pressure sensor is aimed at owners and mechanics working on late-1990s to early-2000s Dodge and Jeep trucks, SUVs, and vans who need a reliable, direct-fit 2-pin replacement. If your vehicle matches the listed years and uses a 2-pin oil pressure sender, this unit is a cost-effective option to restore correct oil pressure reporting. Always verify your vehicle’s system type and connector pin count before purchase to ensure proper fitment.
