Function and Application of the MAP Pressure Sensor

The MAP pressure sensor from the Air and Fuel Intake Sensors category monitors the intake manifold pressure, transmitting a signal to the engine control unit. Based on this, the engine management system calculates the amount of air being drawn in and determines the appropriate fuel dose, which affects the smoothness of operation, performance, and fuel consumption.

In the hybrid BMW i3 I01 with Rex, a properly functioning MAP sensor is particularly important for:

• stable operation of the internal combustion engine under varying loads,
• maintaining the correct fuel-air mixture during transitional modes,
• reducing power drops and jerking when the Rex unit engages,
• ensuring compliance with factory control maps for petrol fuel.

Benefits of Using an Original BMW Sensor

Choosing an original MAP pressure sensor for the BMW i3 I01 allows you to maintain the performance parameters intended by the manufacturer. This component is designed to fit the intake manifold and electrical harness, facilitating installation and minimizing the risk of leaks or reading errors.

Key advantages include:

• factory measurement characteristics – consistent with BMW engine control unit maps,
• secure seating in the intake manifold due to the correct body geometry,
• compatible electrical connector, eliminating the need for wiring modifications,
• maintenance of stable operating parameters across a wide range of loads and temperatures.

Integration with the Petrol Fuel System

In the Rex version, the petrol fuel system works with an advanced control system that utilizes data from air and fuel intake sensors. An efficient MAP sensor:

• supports smooth power delivery from the internal combustion engine,
• reduces the risk of diagnostic errors related to manifold pressure,
• helps maintain predictable load response when the Rex generator is operating.

This ensures the hybrid system maintains proper dynamics, and transitions between electric and combustion operation remain smooth.

Condition, Selection, and Installation

The offered sensor is in Used condition, meaning it has been removed from a dismantled vehicle and is intended for reinstallation. When selecting, pay attention to compatibility with your specific BMW i3 I01 Rex version and fuel type to ensure full compatibility with the control system.

Due to its original origin, installation is close to plug-and-play – the sensor is placed in the designated intake manifold socket, and the electrical harness is connected to the dedicated connector. After installation, it is recommended to perform computer diagnostics to verify operating parameters and clear any stored error codes.
