Standard Motor Products AS313 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS313 is a direct-replacement Manifold Absolute Pressure (MAP) sensor designed for precision performance and long service life. This 4-terminal sensor accurately converts engine vacuum and manifold pressure into an electrical signal that the powertrain control module uses to control fuel delivery and ignition timing.

Key Features:

• 4-terminal design with rectangular female connector and male pin terminals
• Single vacuum port for manifold pressure monitoring
• Converts manifold pressure changes to voltage or frequency signals for optimal engine load measurement
• Essential for speed density fuel injection systems to help the PCM estimate airflow
• Precision-assembled using robotics for consistent quality
• 100% in-line and end-of-line inspection from raw materials through packaging
• O-rings included for proper installation and sealing

What's Included:

• MAP sensor unit
• O-ring seals

A malfunctioning MAP sensor can cause intermittent check engine lights, acceleration hesitation, elevated emissions, and poor engine performance. The AS313 provides OE-quality replacement to restore proper engine management function. This sensor cross-references to OEM part number AA5Z9F479A. Standard Motor Products has over 100 years of engineering expertise in automotive sensors and engine management components, ensuring reliable performance that professional technicians trust.
