Standard Motor Products AS339 Manifold Absolute Pressure MAP Sensor

The Standard Motor Products AS339 is an OEM replacement manifold absolute pressure (MAP) sensor designed to restore proper engine management function. This sensor monitors intake manifold pressure and sends signals to the engine control module (ECM) to optimize fuel delivery, ignition timing, and emissions control.

Key Features:

• Direct OE replacement for reliable fit and function
• Monitors intake manifold vacuum and barometric pressure
• Helps optimize air/fuel ratio and engine performance
• Stock configuration for straightforward installation
• Quality-tested to meet or exceed OEM specifications

MAP sensors are critical for proper engine operation, and a failing sensor can cause poor fuel economy, rough idle, hesitation, and check engine lights. The AS339 provides a cost-effective solution to restore factory performance and reliability.
