A ABIGAIL Oil Pressure Sensor Kit for Chevy GMC Cadillac — 12677836/D1846A with 1-1/16" Socket & Filter

The A ABIGAIL Oil Pressure Sensor kit is a direct-fit replacement pressure switch plus a 1‑1/16" sensor socket designed to restore accurate oil pressure readings on compatible Chevy, GMC and Cadillac models.

This kit includes a durable oil pressure sensor, a protective filter, and a 1‑1/16" (fits 3/8" drive or 1 1/8" hex wrench) socket so you can replace the original unit quickly and get the vehicle's oil pressure reporting back to specifications. The sensor is manufactured to meet or exceed OEM fit standards and lists many original equipment interchange numbers (including 12677836 and D1846A), making it a practical service part for a broad range of GM V6 and V8 engines from the early-2000s to late-2000s.

How does this kit simplify replacement compared with buying parts separately?

By supplying the sensor, a filter, and a dedicated 1‑1/16" socket, the kit reduces trip time to multiple stores and prevents incorrect socket choices that can damage the sensor. The included socket fits standard 3/8" drive tools or a 1 1/8" hex wrench so you can safely remove and tighten the sensor without rounding the hex head.

• One package contains sensor, filter and socket for a single easy service job
• Socket size specifically matches the sensor for proper torque application
• Filter protects the sensor from debris during installation and operation
• OEM interchange numbers help verify fit for your VIN or parts diagram

What should I expect when installing this oil pressure sensor?

Installation is a straightforward mechanical replacement: locate the original pressure switch, remove the electrical connector and old sensor, install the new filter and sensor, then torque to factory specifications and reconnect wiring. No programming is required because this is a passive pressure switch that communicates mechanically/electrically to the vehicle harness.

• Disconnect battery or ignition per safety guidelines before starting
• Use the supplied 1‑1/16" socket with a 3/8" drive for removal/installation
• Replace filter if present and ensure threads are clean before fitting
• Verify oil pressure lamp/gauge operation after installation
