Standard Motor Products AS116 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS116 is a direct-fit OEM replacement Manifold Absolute Pressure (MAP) sensor, also known as a BAPP (Barometric Absolute Pressure) sensor. Engineered to restore proper engine management system function, this sensor provides the powertrain control module (PCM) with accurate manifold pressure readings essential for fuel delivery and ignition timing control.

How It Works:

The MAP sensor monitors changes in intake manifold vacuum and converts that pressure data into a precise voltage or frequency signal. The PCM uses this signal to calculate engine load and adjust ignition timing advance or retard accordingly. On speed-density fuel injection systems, the MAP sensor also assists the PCM in estimating airflow for accurate fuel metering.

Key Features:

• Direct OEM replacement — designed for a plug-and-play, no-modification installation
• Accurately produces voltage or frequency output as manifold pressure changes
• Supports proper ignition timing, fuel delivery, and emissions control
• Built to TS 16949 qualified manufacturing standards for consistent quality
• 100% tested to meet or exceed original equipment specifications
• Sold individually

Symptoms of a Failing MAP Sensor:

• Illuminated check engine light (MIL)
• Hesitation or stumble during acceleration
• Poor fuel economy
• Elevated exhaust emissions
• Rough idle or reduced engine performance

Standard Motor Products has been a trusted name in engine management and emissions components for decades, delivering reliable, OE-quality replacement parts for professional technicians and DIY enthusiasts alike.
