Airtex 5S15120 Manifold Absolute Pressure (MAP) Sensor

The Airtex 5S15120 Manifold Absolute Pressure (MAP) Sensor, also called a manifold air pressure sensor or intake manifold pressure sensor, is a replacement engine management sensor. It measures the pressure or vacuum inside the intake manifold and sends that reading to the engine control unit (ECU). The ECU uses the signal to adjust fuel delivery and ignition timing for efficient combustion.

Key Features:

• Measures intake manifold pressure and converts it to a voltage signal for the ECU
• 3-terminal electrical connection
• Helps maintain proper air/fuel mixture, smooth idle, fuel economy and emissions control
• Replaces a failed or out-of-range sensor

A failing MAP sensor can cause rough idle, hesitation, poor fuel economy, black smoke, failed emissions tests, or an illuminated Check Engine light. Replacing it restores accurate pressure readings to the engine computer.
