• Description: The frequently used abbreviation "MAP sensors" is derived from the term "manifold absolute pressure". Some models also have an NTC as a temperature sensor (NTC= Negative Temperature Coefficient). Here, the influence of the temperature on the density is taken into consideration. The product range comprises almost 30 types. With around 80 OE references, these sensors cover almost 900 applications at Audi, VW, Skoda, Seat, Opel, Vauxhall, Fiat, and PSA.
  Technical information
  - In some vehicles, MAP sensors are used instead of air mass sensors to calculate the air mass.
  - The boost pressure sensor measures the absolute pressure in front of the throttle valve.
  - The engine control unit uses the signal from this sensor to calculate a correction value for the boost pressure.
  - The intake manifold pressure sensor measures the absolute pressure in the intake manifold behind the throttle valve.
  - Together with the signals from the speed sensor and the intake air temperature feeler, this can be used to calculate the air mass that has been taken in.
  Diagnostic information
  - Pressure sensors can be checked using a scan tool, a multimeter, a vacuum hand pump, a thermometer, and a heat source. The scan tool is used to compare the actual values with the set-point values. If the intake manifold pressure measured by the system deviates from the set-point value, the actual value must be checked with a separate vacuum manometer. If the measured intake manifold pressure lies within the set-point values, the MAP sensor and the electrical lines need to be checked. If the measured intake manifold pressure lies outside the set-point values, the cause of the pressure loss at the engine must be determined.
