Ruizure Engine Oil Pressure Sensor Sender Switch PS638 for Jeep & Dodge 2013–2017 — OE-Fit Direct Replacement

Ruizure PS638 is a direct-fit engine oil pressure sensor/sender switch designed to monitor oil pressure and restore accurate warning light or gauge readings on compatible 2013–2017 vehicles.

When your vehicle reports oil pressure faults or the gauge behaves inconsistently, a failing pressure sensor is often the cause. The Ruizure PS638 replacement is manufactured to match OE fitment and electrical function for a set of Jeep, Dodge, Chrysler, Fiat, and Ram models. It provides reliable pressure feedback to the vehicle’s engine control systems so you can correct alerts and get back to normal operation.

Which vehicles will this Ruizure sensor fit?

The PS638 is built to replace the factory oil pressure sender on specific late-model vehicles. It fits many 2014–2016 Jeep Cherokees and Renegades, 2013–2016 Dodge Darts, select Chrysler 200, Fiat 500X and Ram ProMaster City model years listed by the manufacturer. Always verify the sensor type used in your car — gauge versus warning-light systems can differ.

• Compatible models: 2014–2016 Jeep Cherokee; 2015–2016 Jeep Renegade
• Also for: 2013–2016 Dodge Dart; 2015–2016 Chrysler 200; 2016 Fiat 500X
• Commercial fitment: 2015–2017 Ram ProMaster City
• Check vehicle oil pressure system type in compatibility notes before ordering

How does the PS638 restore correct oil pressure readings?

This sensor converts mechanical oil pressure into an electrical signal sent to your dashboard gauge or the engine control unit. A faulty sender can trigger false warning lights, erratic gauge behavior, or diagnostic trouble codes; swapping in a proper replacement restores accurate reporting and helps the vehicle respond correctly to real oil pressure conditions.

• Restores correct electrical signal for gauge or warning light systems
• Reduces false oil pressure alerts and prevents unnecessary diagnostics
• Matches OEM electrical and thread specifications for secure installation

What are the interchange numbers and part cross-references?

To simplify finding the right part, the Ruizure PS638 lists multiple equivalent part numbers used by various suppliers and manufacturers. If your current sensor shows one of these codes, the PS638 is likely the correct replacement, but always compare connectors and thread sizes to be sure.

• Common cross-references: PS638, PS-638, 1S12029
• Other listed numbers: 926-552, 50047588, PS753, 68145662AA/AB
• Additional codes: OP7638, SBC1165, 50-1249, V33-73-0028

How durable and supported is the Ruizure replacement?

The PS638 is made with corrosion-resistant materials and designed to withstand engine-bay heat, vibration, and oil exposure. Ruizure offers a two-year warranty on this sensor, and the part is engineered to deliver stable electrical performance under normal driving conditions.

• Constructed for oil- and heat-resistant durability
• Two-year product warranty for added confidence
• Manufactured to meet common OE fit and function standards

Who is this for: The Ruizure PS638 oil pressure sensor is intended for drivers, DIY mechanics, and professional technicians who need a reliable, direct-fit replacement for the listed Jeep, Dodge, Chrysler, Fiat, or Ram models. It’s suitable when you see an oil pressure warning light, erratic gauge behavior, or diagnostic codes tied to the oil pressure circuit — but always confirm your vehicle’s pressure-sender type and part number before purchase to ensure compatibility.
