Detailed Description

Dorman 926-040 is an OE-style replacement oil pressure sensor for select Chevrolet, GMC, Cadillac, Buick, Pontiac, and Hummer vehicles. It is designed to match the original sensor form and function, making it a practical choice for repairs on applications including the Chevrolet Corvette, GMC Yukon, and Pontiac Grand Prix. This part cross-references ACDelco 12585328 for the same application.

As an engine oil pressure sensor, this component monitors oil pressure and sends the signal used by the vehicle’s control systems and gauge display. When the original sensor becomes inaccurate or fails, the replacement can help restore proper oil pressure readings on supported GM trucks, SUVs, and performance cars.

What It Helps Address

• Inaccurate oil pressure gauge readings
• Oil pressure warning light concerns
• Intermittent sensor signal loss
• Faulty readings caused by heat or pressure exposure
• Replacement needs after sensor wear or electrical failure

Installation Notes and Tips

Verify connector style, terminal count, and sensor location before installation. This part uses a round 1-connector, 3-terminal male configuration, so matching the original connector is important for proper fitment. Confirm vehicle application by year, make, and model before ordering, especially on GM platforms such as the Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, and Cadillac CTS.

For best results, inspect the connector and surrounding wiring for corrosion or damage before installing the new sensor. Proper installation is important to ensure accurate oil pressure signal transfer after replacement.

Quality Assurance

Dorman designs this replacement sensor to meet the operating pressure and temperature demands of the application. The part is built as a direct replacement for specified vehicles, with construction intended to support reliable engine oil pressure monitoring in normal service.
