GM Genuine Parts Engine Oil Pressure Sensor - OEM Fit and Value

In this review of the GM Genuine Parts 12674782 Engine Oil Pressure Sensor the bottom line is simple: this is a direct-replacement sensor for many GM models that delivers OEM fit and consistent function for drivers who need to restore accurate oil pressure readings. The reviewer found the part to be engineered to General Motors standards and backed by the GM Genuine Parts program, making it a straightforward choice for owners of compatible Malibu, Impala, Camaro and other GM vehicles who want a reliable, factory-validated component.

Key Features

• OE Validation: The sensor is a GM Genuine Parts unit, engineered and tested to meet the same standards used during vehicle production, so buyers get a familiar factory-quality component.
• Wide Vehicle Coverage: It fits a broad range of GM models and engine sizes from 2.8L and 3.0L to 3.6L, making it useful for owners of Malibu, Impala, Camaro, ATS and other listed vehicles.
• Direct Fit: The part provides the correct OEM fit for compatible vehicles, reducing the chance of modification or adapter use during installation.
• Backed by GM: Being backed by General Motors means documentation and part validation are available, which helps when matching parts to VINs or service manuals.
• Resolves Pressure Issues: Customers report the sensor resolved low oil pressure readings, restoring expected gauge behavior and engine protection functions.

Who It's For

This sensor is aimed at DIY owners and professional technicians working on compatible GM sedans, coupes, wagons and SUVs from model years around 2013 through 2016, including Malibu, Malibu Maxx, Impala, CTS-free variants, LaCrosse, Camaro, and others listed in compatibility notes. It is a good choice when the vehicle exhibits incorrect oil pressure readings, warning lights, or when replacing a failed original sensor with a validated OEM part.

Those who should look elsewhere include owners of non-GM vehicles, or anyone whose engine or model year is not listed among the supported applications. Also, if a customer needs a sensor with vehicle-specific performance upgrades beyond factory specifications, an aftermarket performance sensor might be considered instead of an OEM replacement.
