Standard Motor Products AS328 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS328 is a direct-fit Manifold Absolute Pressure (MAP) sensor engineered to restore precise intake manifold pressure readings to your vehicle's engine management system. Also referred to as a BAPP (Barometric Absolute Pressure/Pressure) sensor in some applications, this sensor plays a critical role in calculating the correct air-fuel mixture for efficient combustion and optimal engine performance.

The MAP sensor continuously monitors the pressure inside the intake manifold and transmits that data to the Engine Control Module (ECM). This allows the ECM to adjust fuel injection timing, ignition timing, and other critical parameters in real time. A faulty MAP sensor can result in poor fuel economy, rough idling, hesitation, or a check engine light.

Key Features:

• Direct OE replacement for a precise, hassle-free fit
• Designed to meet or exceed original equipment specifications
• Restores accurate manifold pressure signal to the ECM
• Helps correct issues such as rough idle, poor acceleration, and failed emissions tests
• Manufactured by Standard Motor Products, a trusted name in engine management components
• Also functions as a Barometric Absolute Pressure (BAPP) sensor where applicable

Standard Motor Products has been a leading supplier of engine management and electrical components for over 100 years. The AS328 is built to exacting quality standards, ensuring long-lasting, dependable performance as a replacement for a worn or failed OEM sensor.
