Airtex 5S11646 Manifold Absolute Pressure (MAP) Sensor

The Airtex 5S11646 Manifold Absolute Pressure (MAP) Sensor, also called a manifold pressure sensor or intake manifold pressure sensor, is a replacement engine management sensor. It measures the pressure inside the intake manifold and reports it to the engine control module.

Key Features:

• Monitors intake manifold pressure and sends a voltage signal to the engine computer
• Gives the ECU data it uses to calculate air density and set fuel delivery and ignition timing
• Also gives a barometric reading with the key on and the engine off, which helps the ECU adjust for altitude and weather
• Replacement sensor from Airtex Engine Management

A failing MAP sensor can trigger the check engine light and cause drivability or fuel economy problems. Replacing it restores accurate pressure readings so the engine can keep the correct air/fuel mixture.
