A ABIGAIL Oil Pressure Sensor Kit for Chevy GMC Cadillac — 1 1/16" Socket Included, Direct-Fit for 1997–2008 GM V6/V8

The A ABIGAIL Oil Pressure Sensor kit replaces worn sensors and includes a dedicated 1 1/16" socket for fast, correct installation on many Chevy, GMC and Cadillac engines.

This complete replacement assembly is designed for mid-2000s GM V6 and V8 applications and pairs a direct-fit pressure switch with a purpose-built socket so you can install the part without guessing on tools. Built from corrosion-resistant materials and matched to common GM OE numbers, the sensor transmits oil-pressure information to the vehicle’s monitoring systems while the socket prevents rounding and speeds removal and reinstallation.

Will this sensor fit my Chevy, GMC or Cadillac?

The kit is cross-referenced to multiple factory part numbers and covers a broad range of GM models from roughly 1997–2008, including Silverado, Sierra, Tahoe, Suburban, Avalanche, Express, Yukon, Envoy, Savana, Corvette and select Cadillacs. Check your vehicle’s engine size and model year against the compatibility list before ordering to ensure a match.

• Replaces many OEM numbers such as 12677836, D1846A, OP6196 and others
• Compatible with 4.8L, 5.3L, 5.7L, 6.0L, 6.2L and 7.0L engines specified in the listing
• Fitment includes Silverado/Sierra 1500–3500, Tahoe, Suburban, Avalanche, Express, Corvette, Envoy, Savana and select Cadillac models

How does the included socket make installation easier?

The kit includes a 1 1/16" socket sized to reach and remove the sensor without damaging the electrical connector or surrounding fittings. That dedicated socket fits a 3/8" drive and also accepts a 1 1/8" hex wrench, reducing the chance of stripped flats and unnecessary labor time.

• Socket accepts 3/8" drive ratchet or 1 1/8" hex wrench
• Prevents rounding of sensor hex during removal and installation
• Saves time versus improvised or incorrect tools in tight engine bays

What materials and quality controls are in this kit?

The sensor body and connector are made from durable, corrosion-resistant materials selected for long service life in typical engine environments. The unit is manufactured to meet or exceed common OEM tolerances and comes with a filter element to protect the sensing port from contaminants during installation.

• Corrosion-resistant sensor housing for durability
• Includes protective filter to guard the sensing orifice
• Manufactured to match OEM fit and electrical characteristics

What should I expect after installing the replacement sensor?

Once installed, the vehicle’s instrument cluster or engine module will resume receiving oil-pressure data from the new sensor, which can restore proper gauge readings or pressure-related warnings. If a fault persists after installation, diagnostics of wiring and module connections may be necessary.

• Restores accurate oil-pressure reporting to vehicle systems
• May clear pressure-related dash warnings if sensor was faulty
• If issues continue, inspect wiring, connectors and module inputs

Who is this for: This A ABIGAIL sensor-and-socket kit is aimed at DIY owners, independent mechanics and fleet technicians working on compatible GM trucks, SUVs and performance cars from the late 1990s through the 2000s. It suits anyone who wants a direct-fit replacement and the correct removal tool in a single purchase to reduce shop time and lower the risk of installation damage.
