Standard Motor Products AS737 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS737 is a high-quality replacement Manifold Absolute Pressure (MAP) sensor designed to restore proper engine performance and efficiency. This precision-engineered sensor accurately measures manifold pressure and converts it to an electrical signal that the engine control module uses to optimize fuel delivery and ignition timing.

Key Features:

• 3-terminal design for reliable electrical connection
• Manufactured using advanced robotics for precision assembly
• Subject to 100% in-line and end-of-line inspection for quality assurance
• Direct replacement for worn, damaged, or malfunctioning OEM MAP sensors
• Accurately produces voltage or frequency signals as manifold pressure changes
• Engineered for precision performance, durability, and long service life

Function and Benefits:

The MAP sensor plays a critical role in engine management by measuring engine vacuum and manifold pressure. The ECU uses this data to calculate engine load, allowing it to advance or retard ignition timing as needed for optimal performance. On speed-density fuel injection systems, the MAP sensor also helps the powertrain control module estimate airflow for precise fuel metering.

Common Symptoms of a Failing MAP Sensor:

• Intermittent or constant check engine light illumination
• Hesitation or stumbling during acceleration
• Poor fuel economy
• Rough idle or engine stalling
• Elevated emissions and failed emissions testing
• Reduced engine performance and power

Standard Motor Products has over 100 years of experience manufacturing trusted replacement parts for professional technicians and DIY enthusiasts. Each sensor undergoes rigorous testing and validation to ensure it not only fits properly but performs reliably over the long term.
