A ABIGAIL Oil Pressure Sensor 12677836 Compatible with Chevy/GMC (Direct-Fit, OEM Replacement)

A ABIGAIL Oil Pressure Sensor (part 12677836) is a direct-fit replacement that monitors engine oil pressure and relays accurate readings to your vehicle’s systems for proper operation.

If your Chevy, GMC, Cadillac or Buick displays erratic oil pressure readings, warning lights, or you suspect a failing sender, this direct-replacement sensor restores reliable monitoring without modifying factory wiring or mounts. Designed to match OEM mounting, electrical connections, and pressure response ranges, the A ABIGAIL unit replaces several GM part numbers so you can get a plug-and-play swap for many late‑model GM platforms.

Which vehicles will this sensor fit?

This sensor is built to be compatible with a wide range of GM cars, trucks and SUVs from the early 2000s into the mid‑2010s. Always double-check your vehicle’s year, engine and current part number before purchasing to ensure proper fitment.

• Common fits include Chevy Silverado 1500/2500/3500, Suburban, Tahoe, Avalanche, Express, Camaro, Colorado, Trailblazer, Avalanche.
• Also compatible with GMC Sierra, Yukon, Savana, Envoy and Buick/Cadillac models such as Allure, CTS, Escalade within listed years.

How does this sensor perform compared with the factory part?

The A ABIGAIL sensor is manufactured to meet or exceed typical OEM standards for durability and electrical performance, offering a cost-effective replacement without reprogramming. It transmits oil pressure data to the instrument cluster or engine control module just like the original sender.

• Durable housing and electrical connector designed for engine bay conditions.
• Engineered to deliver consistent signal voltage across operating pressures.
• Direct electrical and mechanical compatibility for straightforward installation.

What symptoms indicate the oil pressure sensor needs replacing?

Failing senders often reveal themselves through warning lights or inconsistent gauge behavior, but symptoms can vary depending on wiring and vehicle diagnostics. Replacing a defective sensor typically stops false alerts and restores accurate dashboard readings.

• Oil pressure warning light illuminated intermittently or constantly.
• Oil gauge jumps, reads zero, or shows incorrect pressure values.
• Stored fault codes related to oil pressure sensor circuit in the ECU.

How simple is installation and what should I check during replacement?

Installation is straightforward for anyone comfortable working around an engine: unplug the electrical connector, remove the old sensor, apply thread sealant if required, and install the new unit. Verify there are no oil leaks and clear any related fault codes after installation.

• Use the correct wrench size and a torque spec close to OEM recommendations to avoid overtightening.
• Inspect the connector and wiring harness for corrosion or damage before installing the new sensor.
• After install, start the engine and watch the gauge/warning lights; scan for and clear any stored codes.

Who this is for: Drivers, fleet owners, and DIY mechanics who maintain GM trucks, SUVs, or sedans from the 2003–2015 era and need an affordable, direct-fit oil pressure sensor replacement are the ideal buyers. This A ABIGAIL sensor suits anyone seeking a reliable aftermarket option that replaces multiple OEM part numbers, restores proper instrumentation behavior, and keeps engine monitoring functioning without lengthy downtime. If you require exact fit verification, consult your vehicle’s parts diagram or the compatibility chart before ordering.
