BMW MAP Sensor - FAE 13628657300

Product Information

This Manifold Absolute Pressure (MAP) sensor from FAE is a direct replacement for turbocharged BMW applications. It monitors intake manifold pressure and sends critical data to the ECU to ensure accurate fuel injection and ignition timing under varying engine loads. If the MAP sensor fails or sends incorrect readings, it can lead to poor drivability, rough idle, and decreased fuel efficiency.

Manifold Absolute Pressure Sensor
The MAP sensor is vital for calculating engine load by measuring the pressure within the intake manifold. This allows the ECU to determine the correct air-fuel ratio for optimal performance, fuel economy, and emissions regulation—especially under boost conditions in turbocharged engines.

Failure Symptoms:

• Check engine light: Commonly triggered by faulty MAP readings.
• Poor engine performance: Hesitation, sluggish throttle response, or power loss.
• Rough idle or stalling: Caused by inaccurate intake pressure feedback disrupting ECU calculations.
