Arrangement

B18 Altitude sensor

The altitude sensor is located at the front left on the air filter housing.

Task

The altitude sensor detects the atmospheric pressure of ambient air which can be used to make height adaptations on the engine control.

Design

1 Pin 1 Sensor ground

2 Pin 2 Signal voltage

3 Pin 3 Sensor voltage (5 V)

B18 Altitude sensor

A Pressure gauge connection

B Diaphragm

C Potentiometer

Function

The atmospheric pressure deforms a membrane which acts on a potentiometer. This alters the resistance value of the potentiometer and influences the signal voltage which serves the ME control unit (N3/10) as information about the atmospheric pressure.

The pressure gauge range lies between 0.2 and 2.5 bar.
