Standard Motor Products AS330 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS330 is a direct-fit replacement Manifold Absolute Pressure (MAP) Sensor engineered to restore precise intake pressure monitoring and optimal engine management. Sold individually, this sensor is manufactured to meet or exceed OEM specifications for reliable, long-lasting performance.

How It Works:

The MAP sensor continuously monitors intake manifold vacuum and pressure, converting those readings into an electrical signal sent to the engine control module (ECM). The ECM uses this data to calculate engine load, adjust fuel delivery, and control ignition timing. On speed-density fuel injection systems, the MAP sensor also assists the PCM in estimating airflow for accurate fueling.

Key Features:

• Direct OEM replacement — plug-and-play fitment with no wiring harness included
• Three-terminal connector with male blade terminals mating to a female rectangular plug-in connector
• Single vacuum port for accurate manifold pressure measurement
• Black finish for corrosion resistance and environmental durability
• No mounting brackets or O-rings included — reuse existing hardware from the original sensor
• Manufactured by Standard Motor Products, a leading professional engine management brand with over 100 years of experience
• Part of a portfolio of over 50,000 engine management products covering import and domestic vehicles

Symptoms of a Failing MAP Sensor:

• Intermittent or persistent check engine light
• Hesitation or stumble during acceleration
• Poor fuel economy
• Elevated emissions
• Rough idle or reduced engine performance

The AS330 undergoes rigorous quality testing to ensure accuracy and durability, meeting the automotive industry's strictest standards for engine management components.
