BMW MAP Sensor - Genuine BMW 13627585492

Product Information

This Genuine BMW Manifold Absolute Pressure (MAP) sensor plays a critical role in monitoring turbo boost levels and ensuring accurate engine management. By reading pressure inside the intake manifold, it enables the ECU to calculate air density and optimize fuel delivery and ignition timing. A failing MAP sensor can disrupt this balance, leading to poor boost response or idle issues—especially in turbocharged applications.

Manifold Absolute Pressure Sensor
The MAP sensor is a vital part of your vehicle’s engine management system. It provides real-time data to the ECU to maintain the ideal air-fuel mixture under all load conditions, supporting efficient performance, emissions control, and drivability.

Failure Symptoms:

• Check engine light: Often the first sign of MAP sensor malfunction.
• Poor engine performance: Reduced power, hesitation, or sluggish acceleration due to incorrect boost or mixture readings.
• Rough idle or stalling: Caused by inaccurate manifold pressure feedback disrupting ECU calculations.
