Airtex 5S2549 Manifold Absolute Pressure (MAP) Sensor

The Airtex 5S2549 Manifold Absolute Pressure (MAP) Sensor is a replacement engine management sensor. It measures the pressure (vacuum) inside the intake manifold and sends that reading to the engine control module (ECM). The ECM uses the signal to adjust fuel delivery and ignition timing as engine load and atmospheric conditions change.

Key Features:

• Reports intake manifold pressure to the vehicle's onboard computer so the engine can run smoothly under changing conditions
• Airtex MAP sensors are engineered and tested to meet or exceed OE specifications
• Helps maintain proper engine performance, fuel efficiency and emissions control
• Direct-fit replacement for a worn or failed MAP sensor

A failing MAP sensor can cause hesitation, rough idle, poor fuel economy, increased emissions or a Check Engine light. Replacing it restores accurate manifold pressure readings to the ECM.
