Standard Motor Products AS23 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS23 is a direct-fit Manifold Absolute Pressure (MAP) sensor engineered to restore accurate intake manifold pressure monitoring to your vehicle's engine management system. Also known as a BAPP (Barometric Absolute Pressure/Pressure) sensor in some applications, this sensor provides the engine control module (ECM) with critical vacuum and pressure data used to calculate proper fuel delivery and ignition timing.

The MAP sensor measures the pressure inside the intake manifold and converts it into a voltage signal sent to the ECM. A faulty or failing MAP sensor can result in poor fuel economy, rough idle, hesitation, engine misfires, and illumination of the Check Engine Light (MIL). Replacing it with a quality unit like the AS23 restores proper closed-loop engine operation.

Key Features:

• Direct OE replacement — designed to match original equipment fit, form, and function
• Functions as both a MAP (Manifold Absolute Pressure) and BAPP (Barometric Absolute Pressure) sensor where applicable
• Precision-calibrated sensing element for accurate pressure-to-voltage signal output
• Manufactured to meet or exceed OEM specifications
• Plug-and-play installation with no modification required
• Durable construction for long service life under demanding underhood conditions

Standard Motor Products is a trusted OEM-level supplier with decades of experience in engine management and fuel system components. The AS23 MAP sensor is built to the same exacting standards as the original equipment part it replaces, ensuring reliable performance and a proper fit right out of the box.
