Standard Motor Products AS703 Manifold Absolute Pressure MAP Sensor - 3-Terminal

The Standard Motor Products AS703 is a direct-fit replacement Manifold Absolute Pressure (MAP) sensor featuring a 3-terminal connector. Designed to restore proper engine management function, this sensor is engineered for precision performance, durability, and long service life.

The MAP sensor monitors intake manifold pressure and converts it into an electrical signal that the engine control module (ECM) uses to calculate engine load. This data is critical for adjusting ignition timing and fuel delivery in real time. On speed density fuel injection systems, the MAP sensor also assists the powertrain control module (PCM) in estimating airflow into the engine.

Key Features:

• Direct OE replacement for worn or failed manifold absolute pressure sensors
• 3-terminal connector for precise, factory-style fitment
• Accurately produces voltage or frequency output in response to manifold pressure changes
• Supports ignition timing control and fuel delivery optimization
• Compatible with speed density fuel injection systems for PCM airflow estimation
• Sold individually — wiring harness not included
• Manufactured by Standard Motor Products, a trusted name in engine management components for over 100 years

A failing MAP sensor can trigger symptoms such as an intermittent check engine light, hesitation during acceleration, elevated emissions, and reduced engine performance. The Standard Motor Products AS703 restores accurate sensor feedback to keep your engine running at peak efficiency.
