Global Parts 1815078 Manifold Absolute Pressure Sensor

Manifold Absolute Pressure Sensor for GM Applications

Global Parts 1815078 is a manifold absolute pressure (MAP) sensor that reads intake manifold air pressure and sends that data to the ECU for air/fuel mixture calculation. It is a direct-fit emission control sensor for a wide range of Chevrolet, Cadillac, Buick, and GMC vehicles, including Chevrolet Malibu, Camaro, Equinox, Traverse, Corvette, and Cadillac ATS applications.

Key Features

• MAP sensor for fuel-injected engine management
• Measures intake manifold pressure for ECU input
• Blade terminals with 4 terminal connections
• 1 female oval connector for a secure electrical interface
• Bolt-on mount type for straightforward replacement
• Plastic body construction with 1 port
• Cross-references Standard Ignition AS432 for the same application

Detailed Description

Global Parts 1815078 is built for vehicles that rely on manifold pressure data to manage fuel delivery and engine operation. By monitoring pressure inside the intake manifold, this MAP sensor helps the engine control unit determine the correct air/fuel mixture under changing load and throttle conditions. It is used across GM platforms such as Chevrolet Malibu, Chevrolet Camaro, Cadillac CTS, and Buick Regal, making it a practical replacement for common drivability and emissions-related sensor service. This part number, 1815078, also cross-references OE-style numbers including 12612111 and 12644807.

What It Helps Address

• Rough idle caused by inaccurate manifold pressure readings
• Hard starting related to incorrect ECU fuel calculations
• Check engine light concerns tied to MAP sensor faults
• Poor throttle response from unstable intake pressure data
• Fuel mixture issues affecting engine performance and emissions control

Installation Notes and Tips

Verify connector shape, terminal count, and mount style before installation. This sensor uses a female oval connector, 4 blade terminals, and a bolt-on design, so matching the original electrical and mounting layout is important. Confirm the vehicle application by year, make, and model before ordering, especially on GM platforms where sensor configurations can vary by engine package.
