Standard Motor Products AS682 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS682 is a direct-fit replacement manifold absolute pressure (MAP) sensor designed to restore proper engine performance and fuel management. This sensor accurately measures manifold pressure and converts it to a voltage or frequency signal that the engine control module uses to calculate engine load, optimize ignition timing, and control fuel delivery.

Key Features:

• 3-terminal design for accurate pressure monitoring
• Direct replacement for worn or malfunctioning OEM sensors
• Converts manifold vacuum and pressure to electrical signals for the PCM
• Assists with airflow estimation on speed density fuel injection systems
• Helps prevent check engine lights, hesitation, and poor performance caused by faulty MAP sensors

Standard Motor Products MAP sensors are engineered to meet or exceed OEM specifications, providing reliable performance for proper fuel delivery and ignition timing control. A failing MAP sensor can cause intermittent check engine lights, acceleration hesitation, elevated emissions, and reduced engine performance—making timely replacement essential for maintaining optimal vehicle operation.
