A ABIGAIL Oil Pressure Sensor 12677836 Compatible with Chevy/GMC/Cadillac 2003-2015 — Direct-Fit, OEM-Style Connector

A ABIGAIL Oil Pressure Sensor (part 12677836) is a direct-fit replacement sensor that monitors engine oil pressure and relays readings to your vehicle’s control modules and dash indicators.

When an oil pressure sensor fails, your vehicle can display inaccurate gauge readings or trigger warning lights that make diagnosing engine health harder. This A ABIGAIL sensor is engineered as an aftermarket alternative to several OEM numbers and is designed to restore reliable pressure feedback on compatible Chevrolet, GMC, Cadillac, Buick and related models from the mid-2000s to mid-2010s.

Which vehicles will this sensor fit?

This sensor replaces multiple factory part numbers and fits a range of GM platforms. It’s specified for many Chevrolet trucks and SUVs, GMC models, Cadillac sedans and SUVs, and select Buick and Pontiac vehicles—check fitment before ordering.

• Compatible years include 2003–2008 for many Silverado models and coverage extending into 2009–2015 for other GM vehicles.
• Common applications: Chevy Silverado, Suburban, Tahoe, Avalanche, Express, Impala, Corvette; GMC Sierra, Yukon, Savana; Cadillac CTS, Escalade; Buick Allure, and more.
• Cross-references: replaces OEM numbers such as 12556117, 12614969, 12616646, 12677836 and aftermarket references like OP6196, PS308.

How does this sensor communicate oil pressure to the vehicle?

The sensor converts engine oil pressure into an electrical signal that the vehicle’s instrument cluster or engine control module interprets. Proper signal transmission keeps your pressure gauge accurate and ensures warning lights behave correctly.

• Electrical connection matches OEM-style plug for direct replacement installation.
• Durable sensing element resists typical engine heat and oil exposure.
• Signal output designed to meet or exceed factory performance for accurate readings.

What are the main benefits of choosing this aftermarket sensor?

Choosing this A ABIGAIL sensor offers a cost-effective option to restore oil pressure monitoring without buying an OEM unit. It’s produced to fit directly into original mounting locations and aims to deliver consistent operation under normal driving conditions.

• High-quality materials for long service life and corrosion resistance.
• Direct replacement design—no modifications required for compatible vehicles.
• Backed by seller support for troubleshooting, replacement, or refund if installation problems occur.

How should I install and verify the new sensor works?

Installation is typically straightforward: disconnect the battery, remove the electrical connector, unthread the old sensor, and fit the new unit with appropriate torque and sealing. After installation, start the engine and check the dash gauge and any oil-pressure-related fault codes to confirm correct operation.

• Recommended: inspect wiring harness and connector for corrosion before fitting the new sensor.
• Use thread sealant if the vehicle’s service manual specifies it; follow torque recommendations to avoid leaks.
• Verify by monitoring gauge response and scanning for diagnostic trouble codes (DTCs).

Who this is for: This A ABIGAIL oil pressure sensor is aimed at DIY mechanics, professional technicians, and owners of mid-2000s to mid-2010s GM vehicles who need a reliable, affordable replacement for failed or unreliable factory sensors. It’s especially useful when restoring accurate oil pressure readings on Chevrolet Silverado, GMC Sierra, Cadillac CTS/Escalade, and other compatible models. Always confirm vehicle compatibility using your VIN or the part cross-reference list before purchase to ensure a correct fit.
