Measuring Intake Manifold Pressure:
The MAP sensor measures the absolute pressure inside the intake manifold, which is the air pressure after it has passed through the throttle body but before it enters the combustion chambers.
In turbocharged or supercharged engines, the MAP sensor measures the boost pressure, providing the ECU with crucial information to manage the turbo or supercharger's performance and prevent overboost conditions.
Engine Performance:
Accurate pressure readings from the MAP sensor ensure that the engine runs smoothly and efficiently, providing the right amount of power and responsiveness. Maintenance and Replacement
Regular Inspection: Periodically check the MAP sensor and its connections for signs of wear or damage.
Cleanliness: Ensure the sensor and the intake manifold are clean to prevent inaccurate readings.
