Standard Motor Products AS434 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS434 is a direct-fit OE replacement manifold absolute pressure (MAP) sensor designed to restore reliable engine performance and diagnostics. This sensor accurately measures engine vacuum and manifold pressure, converting these readings into electrical signals that the powertrain control module (PCM) uses to calculate engine load, optimize fuel delivery, and adjust ignition timing for maximum efficiency.

Key Features:

• Direct-fit OE replacement design ensures easy installation with no modifications required
• 3-terminal connector with rectangle-shaped female connector and male pin terminals
• High-temperature glass-reinforced plastic case creates a hermetically sealed cavity for the sensor
• Single vacuum port for accurate pressure measurement
• Constructed from high-quality materials engineered to withstand extreme under-hood conditions
• Black color finish with O-rings included for proper sealing
• Undergoes extensive testing to ensure long-term reliability and accuracy

On speed density fuel injection systems, the MAP sensor plays a critical role in helping the PCM estimate airflow for precise fuel calculations. A malfunctioning MAP sensor can cause symptoms such as intermittent check engine lights, hesitation during acceleration, elevated emissions, poor fuel economy, and reduced engine performance. The AS434 is manufactured with complete quality control throughout the production process, backed by Standard Motor Products' 100+ year reputation for supplying professional-grade replacement parts to technicians worldwide.
