Standard Motor Products AS429 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS429 is a direct-fit replacement manifold absolute pressure (MAP) sensor designed to restore proper engine performance and fuel efficiency. This sensor plays a critical role in engine management by accurately measuring manifold pressure changes and converting them into voltage or frequency signals that the powertrain control module uses to calculate engine load, adjust ignition timing, and optimize fuel delivery.

Key Features:

• Direct-fit OE replacement design ensures easy installation with no modifications
• High-quality construction withstands extreme underhood temperatures and conditions
• Lab tested to match OE specifications for seamless integration with vehicle emissions systems
• Precision engineered to help maintain engine efficiency and reduce component stress
• 3-terminal connector configuration
• Extensively tested to ensure long-term reliability

A malfunctioning MAP sensor can cause various drivability issues including intermittent check engine lights, hesitation during acceleration, elevated emissions, and poor overall engine performance. On speed density fuel injection systems, the MAP sensor also assists the PCM in estimating airflow for proper fuel metering. Replace your worn or damaged MAP sensor with this quality Standard Motor Products unit to keep your vehicle running at peak performance.
