ACDelco 24264189 GM Original Equipment Fuel Injection Manifold Absolute Pressure Sensor

The ACDelco 24264189 is a GM Original Equipment Fuel Injection Manifold Absolute Pressure (MAP) Sensor designed to deliver the same fit, form, and function as the factory-installed component it replaces. As a genuine GM OE part, it meets the exact specifications set by General Motors engineers for reliable, long-term performance.

The manifold absolute pressure sensor monitors the pressure inside the intake manifold and sends a real-time signal to the engine control module (ECM). This data is used to calculate engine load and optimize fuel delivery, ignition timing, and emissions performance. A faulty MAP sensor can result in rough idle, poor fuel economy, hesitation under acceleration, and failed emissions tests.

Key Features:

• Genuine GM Original Equipment — manufactured to OEM specifications
• Direct factory replacement for a precise, no-modification fit
• Monitors intake manifold pressure to support accurate fuel injection control
• Helps maintain proper air/fuel ratio, engine efficiency, and emissions compliance
• Engineered for the same durability and service life as the original factory sensor
• Plug-and-play installation — uses existing wiring harness connector

Choosing a genuine ACDelco GM Original Equipment MAP sensor ensures your vehicle's fuel injection and engine management system operates exactly as designed. This sensor is the same part installed at the factory, providing confidence in performance, reliability, and longevity.
