Bosch Manifold Absolute Pressure Sensor

The Bosch Manifold Absolute Pressure (MAP) Sensor, also called a MAP sensor or intake manifold pressure sensor, measures the pressure inside the intake manifold. It sends that data to the engine control unit (ECU). The ECU uses the signal, along with other inputs, to calculate engine load and air mass. It then adjusts fuel delivery and ignition timing to match.

Key Features:

• Gives the engine control unit accurate intake manifold pressure readings for fuel and ignition management
• Supports efficient combustion, smooth idle, steady throttle response, and lower emissions
• Made to meet original-equipment specifications for fit, function, and signal output
• Built for the heat, vibration, and automotive fluids found in an engine bay
• Often combined with an intake air temperature sensor in one housing, depending on the application
• Direct-fit replacement design that normally needs only basic hand tools

A failing MAP sensor can cause a check engine light, rough idle, hesitation, poor fuel economy, or hard starting. Fitting a new Bosch sensor restores correct engine data to the ECU.
