Component description for intake manifold pressure sensor

D07.04-1180-05

Location

Shown on engine 651.955

B2/12 Hot film mass air flow sensor

B28/17 Intake manifold pressure sensor

The intake manifold pressure sensor is located on the air filter housing next to the hot film MAF sensor.

Task

The intake manifold pressure sensor detects the vacuum (absolute pressure) in the intake tract and transmits the change in resistance to the CDI control unit (N3/28).

Input and output signals

Direct output signals

- Change in resistance at the CDI control unit

Function

The air pressure in the air filter distorts a measurement membrane with stretch resistors. The subsequent change in resistance results in a voltage which is used by the CDI control unit for determining the air pressure in the intake manifold.
