BMW MAP Sensor - FAE 13627585493

Product Information

This Manifold Absolute Pressure (MAP) sensor from FAE is designed to accurately monitor intake manifold pressure in turbocharged BMW engines. The sensor communicates critical boost pressure data to the ECU, enabling it to adjust fuel injection and ignition timing for optimal performance, emissions control, and drivability. A faulty MAP sensor can lead to erratic boost levels, poor throttle response, and rough idle.

Manifold Absolute Pressure Sensor
The MAP sensor plays a vital role in engine management by helping the ECU calculate the correct air-fuel ratio based on intake pressure. Accurate readings are especially important in forced induction systems to prevent drivability issues and to ensure emissions compliance.

Failure Symptoms:

• Check engine light: Commonly triggered by faulty MAP sensor signals.
• Reduced engine performance: Includes sluggish acceleration, poor boost response, or hesitation.
• Rough idle or stalling: Inaccurate pressure readings can disrupt fuel mapping and idle control.
