Standard Motor Products AS671 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS671 is a direct-fit OE replacement Manifold Absolute Pressure (MAP) sensor designed to accurately monitor engine vacuum and manifold pressure conditions. This sensor converts manifold pressure changes into electrical signals that the engine control module uses for precise fuel delivery and ignition timing control.

Key Features:

• Direct-fit OE replacement design ensures proper fit, form, and function for accurate pressure measurements
• Features OE-matching connectors and terminals for exact-fit connection to the engine wire harness
• 3-terminal configuration for reliable electrical connection
• Undergoes extensive design and manufacturing processes to ensure superior durability and performance
• Engineered to withstand extreme engine compartment conditions

MAP sensors play a critical role in engine management by helping the PCM measure engine load for optimal ignition timing and fuel system operation. On speed density fuel injection systems, the MAP sensor also assists in estimating airflow. A properly functioning MAP sensor ensures optimal engine performance, fuel efficiency, and emissions control.
