Pressure sensor

Application

  • MAP (Manifold Absolute Pressure) sensor;
  • boost pressure sensor;
  • atmospheric pressure sensor;
  • fuel pressure sensor;
  • fuel tank pressure sensor;
  • oil pressure sensor.
Output voltage waveform from a properly functioning MAP sensor (Mitsubishi Lancer 1.6 2005).
Output voltage waveform from a properly functioning MAP sensor (Mitsubishi Lancer 1.6 2005).

Output voltage waveform from a properly functioning MAP sensor (Mitsubishi Lancer 1.6 2005). The output voltage of the sensor decreases with increasing vacuum in the intake manifold.
A – engine start;
B – running at idle;
C – snap throttle (acceleration);
D – deceleration;
E – running at idle;
F – engine shut off.
