Standard Motor Products AS348 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS348 is a direct-fit replacement Manifold Absolute Pressure (MAP) sensor engineered to restore proper engine management function. Sold individually, this sensor is part of Standard's Intermotor line and is designed as a high-quality OE-equivalent replacement for a worn, damaged, or malfunctioning MAP sensor.

The MAP sensor monitors intake manifold pressure and converts that reading into an electrical signal sent to the powertrain control module (PCM). The PCM uses this data to calculate engine load, enabling precise control of ignition timing and fuel delivery. On speed-density fuel injection systems, the MAP sensor also assists the PCM in estimating intake airflow volume.

A failing MAP sensor can trigger a range of drivability issues, including an intermittent check engine light, hesitation under acceleration, elevated emissions, and overall degraded engine performance. Replacing it with a properly calibrated unit like the AS348 restores accurate sensor feedback and optimal engine operation.
