12677836 Oil Pressure Sensor and Socket for Chevy Silverado

A ABIGAIL oil pressure sensor and included 1-1/16" socket replace worn or failing pressure switches on many Chevy, GMC and Cadillac V8/V6 models to restore accurate oil-pressure signaling.

When an oil pressure switch starts to report incorrect readings or leaks, the vehicle’s instrument cluster or engine control module can receive faulty information. This kit supplies a new A ABIGAIL pressure sensor, a replacement screen/filter, and a dedicated 1-1/16" socket to simplify removal and installation. The part is engineered to match common OEM fitments and works across a broad range of GM trucks, SUVs and sedans from the early 2000s through 2008.

How does replacing this sensor help my vehicle perform?

An accurate oil pressure sensor provides correct pressure readings to the dash indicator and engine management systems, helping you and the vehicle respond appropriately to low-pressure conditions. Installing a fresh sensor and clean screen reduces leak risk and avoids erratic gauge behavior caused by worn or clogged components.

• Prevents false low-pressure warnings that can cause unnecessary worry or repairs.
• Restores proper electrical signaling to the combination meter and ECM inputs.
• New filter reduces contamination risk at the pressure port.
• Socket included to lower the chance of rounding the sensor during removal.
