Dorman Engine Oil Pressure Sensor 926-040 — Direct-Fit Replacement, OE-Style Accuracy

The Dorman 926-040 Engine Oil Pressure Sensor is a direct-fit replacement sensor that restores accurate oil-pressure readings when the original unit fails.

When an engine’s oil-pressure sensor degrades from heat exposure, vibration, or internal wear, you can get false readings, warning lights, or poor performance diagnostics. The Dorman 926-040 is built to match the original sensor’s fit and function for the listed vehicle applications, offering a reliable alternative without reprogramming or modification. It is precision-made to meet tight manufacturing standards and reviewed by automotive experts to help you return your engine-monitoring system to proper operation.

How does this sensor restore oil-pressure monitoring?

The 926-040 replaces a failed pressure sender to re-establish accurate oil-pressure signals to your vehicle’s gauge or ECU. It uses compatible electrical and mechanical interfaces so the replacement behaves like the factory part. Installing this sensor eliminates erroneous low-pressure warnings caused by a defective sender instead of actual oil issues.

• Direct replacement design for matching mounting and electrical connector
• Calibrated to provide correct pressure output ranges for compatible vehicles
• Manufactured to tolerances that reduce signal drift and false alerts

Will this part fit my car without modifications?

The Dorman 926-040 is made to fit specific models and trims that use the same sensor geometry and connector. To confirm fitment, enter your vehicle’s year, make, model and trim into the seller’s garage tool. Correct fit means no cutting, splicing, or programming is typically required.

• Designed to match original mounting threads and sealing surfaces
• Compatible electrical connector shape and pin layout to plug in directly
• Check vehicle compatibility tools to verify before purchase

What materials and quality standards are used?

Dorman manufactures this sensor to stringent specifications to withstand engine bay heat and vibration. The construction emphasizes durability so the unit resists premature failure from thermal cycling or contaminated oil exposure. Backed by decades of automotive parts experience, the product undergoes quality checks before shipping.

• Robust housing materials chosen for thermal and chemical resistance
• Precision internal components to maintain stable pressure output
• Quality reviewed by U.S.-based product experts with extensive automotive background

How simple is installation for a DIYer?

Installation is straightforward for anyone comfortable performing basic engine-bay maintenance: locate the old sensor, disconnect the electrical plug, unthread the sender, and fit the new unit with a proper seal. Use a torque wrench to the manufacturer’s specification and ensure the electrical connector seats fully. If uncertain, a local mechanic can complete the swap quickly.

• Plug-and-play electrical connector to reduce installation time
• Threaded mounting matches original sensor location for easy replacement
• No special programming usually required after installation

Who is this for: The Dorman 926-040 Engine Oil Pressure Sensor is suited for vehicle owners and independent mechanics who need a reliable, cost-effective replacement for a failed factory oil-pressure sender. It’s ideal when the dash gauge or ECU shows inconsistent oil pressure readings and the engine’s oil level and quality are known to be correct. Use the vehicle compatibility tool to confirm fitment before ordering to ensure a hassle-free swap and restore accurate engine oil monitoring.
