ACDelco 12597209 Fuel Injection Manifold Pressure Sensor

The ACDelco 12597209 is a GM Original Equipment Manifold Absolute Pressure (MAP) sensor designed to monitor intake manifold pressure and provide critical data to your vehicle's engine control module. This sensor measures the difference between manifold vacuum and atmospheric pressure, allowing the ECM to calculate engine load and optimize fuel delivery, ignition timing, and emissions control.

Key Features:

• GM Original Equipment quality ensures precise fitment and reliable performance
• Monitors manifold pressure for accurate air/fuel ratio calculations
• Direct replacement for worn or failed factory sensors
• Helps maintain optimal engine performance and fuel efficiency
• Manufactured to meet GM's strict OE specifications

When your MAP sensor fails, you may experience rough idling, poor acceleration, reduced fuel economy, or illuminated check engine lights. This genuine ACDelco sensor restores proper engine management system function and meets the performance standards you expect from General Motors Original Equipment.
