Standard Motor Products AS702 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS702 is a direct-fit replacement Manifold Absolute Pressure (MAP) sensor engineered to restore proper engine management function. Designed to match original equipment specifications, this sensor delivers reliable, accurate pressure readings to the vehicle's powertrain control module (PCM).

The MAP sensor monitors intake manifold vacuum and pressure, converting that data into an electrical signal. The PCM uses this signal to calculate engine load and adjust fuel delivery and ignition timing accordingly. On speed-density fuel injection systems, the MAP sensor also assists the PCM in estimating airflow for precise fuel metering.

Key Features:

• Direct OE replacement for worn, damaged, or malfunctioning MAP sensors
• Accurately produces voltage or frequency output as manifold pressure changes
• Helps the PCM optimize ignition timing advance and retard under varying load conditions
• Supports airflow estimation on speed-density fuel injection systems
• Lab tested to match OE specifications for proper integration with the vehicle's engine management system
• High-grade materials provide resistance to extreme temperature changes and harsh underhood environments
• Sold individually; no wiring harness included

A faulty MAP sensor can trigger symptoms such as an intermittent check engine light, hesitation under acceleration, reduced fuel economy, elevated emissions, and poor overall engine performance. The Standard Motor Products AS702 restores accurate manifold pressure sensing to keep the engine running at peak efficiency.
